· Environmental medicine - an approach to medical care dedicated to the evaluation, management, and prevention of adverse consequences resulting from Environmentally Triggered Illnesses.
· Ecology – branch of biology that deals with the relationship between living organisms and their environment. All living things are interconnected.
· Xenobiotic - chemicals or molecules which are foreign to biological systems. These can cause cancer and/or alter the normal functioning of the biological system.
Regulation of environmental toxins
· No single regulatory agency oversees industrial chemicals (including pesticides, herbicides, household cleaners) to ensure their safety.
· Industrial chemicals are presumed safe until proven hazardous.
· Any toxicity testing that is done typically involves individual compounds rather than the complex mixtures of chemicals that exist in our current environment.
Statistics – chemicals in the environment
· There are 80,000 chemicals registered with the EPA, with 1600 new ones submitted for approval every year; less than 10% have been evaluated for safety, and most that have been evaluated for safety have been studied only in young healthy males (not pregnant women or children), and studied in isolation, not in combination with other chemicals.
· There are over 3800 high-volume chemicals produced in the U.S. Less than half have been tested for toxic effects on humans and less than 10% have been tested for toxic effects on children.
· 1500 hazardous substances can be found in the typical North American home.
There are over 10,000 food and chemical
additives allowed into the
There are approximately 16,000 different
pesticide products used in the
According to the EPA, 1.23 billion pounds of
conventional pesticides are used annually in the
· According to the EPA, in 2000 more than 4 billion pounds of chemicals were discharged into the ground, nearly 2 billion pounds of chemicals were released into the atmosphere, and over 260 million pounds of chemicals were discharged into surface waters.
· More than 65,000 metric tons of flame retardants (containing PBDE) are manufactured each year - these are used in a variety of consumer products such as fabrics and Styrofoam.
· As many as 40 distinct carcinogens may be in our water supply.
· As many as 60 distinct carcinogens are released into the air by industrial processes.
· As many as 66 distinct carcinogens are sprayed on food crops as pesticides.
· Fertilizer, especially ‘Zn fertilizer’ is sometimes manufactured from industrial waste – in one study, 20 of 29 fertilizers purchased in 12 states contained levels of toxins (i.e. arsenic, cadmium, chromium, lead, mercury, and dioxins) that exceeded EPA limits.
· According to the rules that govern the chemical industry, new compounds for human use can be introduced without proof of safety - once on the market they must be proved unsafe to be removed from the market.
· Recent research from the American Water Works Association has found significant amounts of prescription drugs including birth control hormones in the water supply, along with herbicides and fragrances.

Pollution/environmental toxin exposure and effects on humans
· Categories of adverse health effects
o Endocrine disruption (especially thyroid and sex hormones)– extremely low levels are pertinent (i.e. bisphenol A is equipotent with estradiol at levels of only ppt, in part because all BPA circulating in the blood is free, whereas 99% of the circulating estradiol is bound by serum proteins).
o Immunologic dysfunction
o Inflammation – inflammatory cytokine upregulation, stimulation of tumor necrosis factor
o Metabolic disruption (blood sugar regulation disruption)
o Methylation disruption
o Mitochondrial damage
o PPAR agonist - POPs
· Body burden testing – chemicals in our bodies
o Bill Moyers – as a part of the 2001 PBS series, Mt Sinai School of Medicine analyzed Bill Moyer’s blood and urine and identified 84 distinct chemicals, many of which are known to be carcinogenic or hormone disruptors.
o Infants – Environmental Working Group (www.ewg.org) in 2005 analyzed umbilical cord blood from 10 babies and found an average of 200 industrial chemicals and pollutants
o Testing of non-occupationally exposed adults for 215 common high use compounds revealed evidence of 167 of the 215 compounds in humans, with an average of 91 toxins per person (www.ewg.org)
§ 76 chemicals of the 167 linked to cancer in humans or animals (average of 53 per person)
§ 94 chemicals of the 167 are toxic to the brain and nervous system (average of 62)
§ 86 chemicals of the 167 interfere with the hormone system (average of 58)
§ 79 chemicals of the 167 are associated with birth defects or abnormal development (average of 55)
§ 77 chemicals of the 167 are toxic to the reproductive system (average of 55)
§ 77 chemicals of the 167 are toxic to the immune system (average of 53)
o CDC environmental health lab in 2005 is monitoring the concentrations in blood and urine of 150 chemicals found in common household supplies, including phthalates (plasticizers), disinfectants, and insecticides. This program is monitoring chemical exposure, not health risk.
o CDC - National Report on Human Exposure to Environmental Chemicals, based on NHANES data
§ First report issued in March 2001, based on exposure data for 27 chemicals in NHANES 1999-2000.
§ Second report issued in January 2003, based on exposure data for 116 chemicals in NHANES 1999-2000.
§ Third report issued in July 2005, based on exposure data for 148 chemicals in NHANES 2001-2002.
§ Fourth report issued in 2009, based on exposure data for 212 chemicals from NHANES 1999-2004 (Altern Med Review. 2010. 15. 101-119).
§ There have since been several updates.
· Precocious puberty is increasing, and there is data that much of the increase is related to environmental xenoestrogens (i.e. phthalates, shampoos and personal care products with estrogenic substances, which are widely used in African American communities).
· One study showed that 27% of African American girls began developing breasts and pubic hair by age 7; 48% reached this stage by age 8. 3% of African American girls and 1% of Caucasian girls showed breast development and pubic hair by age 3! (Pediatrics. 1997. 99. 505-512).
· Data from NHANES 1988-1994 showed that 49% of African American girls showed breast development by age 9, compared with 24.5% of Mexican Americans and 15.8% of Caucasians (Pediatrics. 2002. 110. 752-757).
· Sperm counts in men have dropped from 125 million/ml in 1932 to 50 million/ml in 1998; size of genitals in males is smaller in those individuals with higher levels of pesticides and phthalates.
· Dioxins (more information below) bioaccumulate in fatty tissue; highest levels are in breast milk.
· Mercury - in 2005, interim results from Greenpeaces Mercury Hair Sampling Project at the University of North Carolina-Asheville reported that mercury levels exceeded the EPA limit of 1 microgram of mercury per gram of hair in 21% of the 597 women of childbearing age tested. Mercury levels were correlated with fish consumption.
· PBDEs (more information below) - potential effects on human health are unknown; toxicological studies show that these compounds are neurotoxins, carcinogens, and endocrine disruptors.
o PFCs (more information below) – carcinogenic in animals, and probably in humans
o Persistent organic pollutants (i.e. PCBs, dioxins, furans, pesticides) bio-accumulate in humans over time. Among approximately 1900 subjects selected in 1999 and 2000 from the NHANES III database, at least 90% had detectable levels of DDT, and at least 50% had detectable levels of urinary organophosphate insecticide metabolites (DHHS publication # 02-0716. 2003).
o Phthalates (more information below) – endocrine disruptors
Pollution and human disease
· Environmental pollutant-related illness in children costs $54.9 billion annually in the U.S. including $43 billion for lead poisoning, $9.2 billion for neurobehavioral disorders, $2 billion for asthma, 0.3 billion for childhood cancers (Environ Health Perspect. 2002. 110. 721-728).
· Children are at highest risk
o Consume more air, food and water per body weight
o Put more things in their mouths
o Breathing zones closer to the ground
o Detoxification mechanisms immature
· Incidence rates for childhood cancer increased 21% between 1975 and 1998, approximately 1% each year, due to unexplained environmental influences. An expert panel convened by Mt Sinai Hospital concluded that genetic predisposition accounts for only approximately 20% of childhood cancers.
Arsenic and diabetes type II (Kile ML and
o Millions of individuals worldwide are exposed to inorganic arsenic in drinking water (actually most often from contamination of water from natural mineral deposits rather than pollution) [Appl Geochem. 2002. 17. 517-568]. In the US, approximately 13 million people live in areas with a concentration of inorganic arsenic in the public water supply that exceeds the EPA standard of 10 mdg/L (Fed Regist. 2001. 66. 6976-7066).
o Arsenic exposure was first linked to diabetes in 1950 based on a case report of diabetes developing in an individual receiving intravenous arsenical treatment for a STD (Am J Med. 1950. 9. 124-132).
o In multiple epidemiologic studies in the 1990’s, high chronic exposure to inorganic arsenic in drinking water (>100 mcg/L) is associated with diabetes, with a dose response relationship noted.
o High occupational exposure to organic arsenic is associated with higher levels of glycosylated hemoglobin (Analyst. 1998. 123. 77-80).
o Humans are exposed to organic arsenic compounds in seafood, but these are metabolized into compounds considered nontoxic (Carcinogenesis. 1991. 12. 1287-1291).
o NHANES IV data (2003-2004) in 788 adults who had a urinary arsenic determination showed that after adjustment for biomarkers of seafood intake, total urinary arsenic was associated with increased prevalence of diabetes type II. After adjustment for diabetes risk factors and markers of seafood intake, the odds ratio for diabetes type II in participants in the 80th vs. the 20th percentile of total urinary arsenic was 3.58 (whereas the odds ratio was 0.69 for arsenobetaine, the organic arsenic compound found in seafood) [JAMA. 2008. 300. 814-822]. Calculations would suggest that even those individuals in with the highest percentile of total urinary arsenic were exposed to less than the current EPA standard of 0.3 mcg/kg of body weight/day. A limitation of this data is that urinary arsenic, with a half life of approximately 3days, is a biomarker of short term exposure to arsenic (Editorial. JAMA. 2008. 300. 845-846).
· Arsenic and cardiovascular disease (inorganic arsenic occurs naturally in groundwater)
o High arsenic in drinking water (>100 mcg/L) is associated with increased risk of peripheral vascular disease, coronary heart disease, stroke, and carotid atherosclerosis, based on studies in studies in Taiwan, Bangladesh, Chile, Inner Mongolia, and Pakistan (References 2-11 of Ann Intern Med. 2013. 159. 649-659).
o A prospective cohort study of 3575 American Indian men and women, with 20 years of follow up, shows that “exposure to low to moderate levels of arsenic, as measured in the urine, was associated with increased risk for fatal and nonfatal cardiovascular disease (Ann Intern Med. 2013. 159. 649-659 and editorial 713-714).
· Lead and adverse health outcomes - serum lead levels even within the ‘normal’ range (i.e. < 10 mcg/dl) are associated with adverse health outcomes – 12 year data in 13,946 adults who had serum lead measured at baseline as part of NHANES III showed that those in the highest tertile (mean level greater than 3.63 mcg/dl) had a 25% greater risk for all cause mortality and a 55% greater risk for cardiovascular mortality, compared with those in the lowest tertile (mean level less than 1.94 mcg/dl) [Circulation. 2006. 114. 1388-1394].
o Mercury may increase the risk of MI; the data is mixed
case control study in 8 European countries and
a nested case control study in male health professionals comparing 470 men with
a new diagnosis of CAD with 470 controls did not find an association (
o Organochlorine exposure and human disease
§ Levels of organochlorine pollutants are associated with the risk of autoimmune thyroiditis (Chemosphere. 2007. 69. 118-127).
§ In a cohort of 749 non-diabetic patients in NHANES, there was a clear correlation between exposure to organochlorines and insulin resistance (Diabetes Care. 2007. 30. 622-628).
o Pesticide and herbicide exposure predisposes to diabetes and metabolic syndrome
o In the NHANES Survey, 1999-2002, there was a strong positive association between serum concentrations of persistent organic pollutants (mainly pesticides and herbicides) and prevalence of type 2 diabetes. Subjects in the highest category (> 90th percentile) of exposure, as compared with the lowest category (< 25th percentile), had a 38-fold increase in risk of type 2 diabetes. Obesity was not a risk factor for type 2 diabetes in people with undetectable levels of persistent organic pollutants (Diabetes Care. 2006. 29. 1638-44).
o An editorial addressing the above data states it appears “virtually all of the risk of diabetes conferred by obesity is attributable to persistent organic pollutants, and that obesity is only a vehicle for such chemicals. This possibility is shocking.” (Lancet. 2006. 368. 558-559).
o Case control data – children with leukemia were 4-7 times as likely to have been exposed to pesticides used in the yard or garden, as compared to children without leukemia.
o Exposure to persistent organic pollutants (POPs) is also correlated with metabolic syndrome (Diabetologia. 2007. 50. 1841-1851).
· PFOA (perfluorooctanoic acid) and cardiovascular disease – data in 1216 subjects in NHANES 1999-2003 shows that exposure to PFOA (as determined by serum levels) is associated with CVD (self reported) and PAD (defined as ABI < 0.9). PFOA has been widely used in the manufacture of industrial and consumer products, such as surfactants, lubricants, polishes, paper and textile coating, food packaging, and fire-retarding foams. Drinking water is the primary route of exposure in most populations (Arch Intern Med. 2012. 172. 1397-1403 and Invited Commentary 1403-1405).
· Bisphenol A (BPA) and obesity – data in 2838 participants (aged 6-19 years) in NHANES 2003-2008 show that “Urinary BPA concentration was significantly associated with obesity in this cross sectional study of children and adolescents.” Uncertain whether this is cause and effect versus whether obese children consume greater quantities of processed food with BPA in the packaging (JAMA. 2012. 308. 1113-1121).
Air pollution and human disease
· Air pollution is a complex mixture of compounds in gaseous phase (ozone, carbon monoxide, and nitrogen dioxide) and particulate matter (Editorial. Arch Intern Med. 2008. 168. 911-913).
o Particulate matter is a heterogeneous amalgam of solids and liquids (carbon, sulfates, nitrates, and metals) derived primarily from the combustion of fossil fuels.
o Particulate matter is subdivided into ultrafine particulate matter <0.1 micrometers in aerodynamic diameter, fine particulate matter <2.5 micrometers in aerodynamic diameter and course particulate matter <10 micrometers in aerodynamic diameter.
o The most compelling data on air pollution and human disease implicates the particulate matter (Circulation. 2004. 109. 2655-2671), and specifically the fine particulate matter (JAMA. 2006. 295. 1127-1134) – the greatest risk appears to be to the cardiovascular system, with risk to the lungs also documented, and emerging data on an increased risk of cognitive impairment and DVT (see just below for specific studies with citations).
o Most of the epidemiologic data examines various endpoints as a function of the total level of particulate matter (i.e. particulate matter <10 micrometers in aerodynamic diameter, PM10) – using a database assembled for 108 US counties, researchers concluded that after adjustment for fine particulate matter (PM2.5), there were no statistically significant associations between course particulate matter pollution (i.e. aerodynamic diameter between 2.5 and 10 micrometers) and hospital admissions for cardiovascular and respiratory diseases (JAMA. 2008. 299. 2172-2179).

Mortality in the
· Air pollution and total mortality
o Long term exposure to fine particulate air pollution is associated with increased total mortality in population based studies (Science. 1970. 169. 723-733; Environ Int. 1984. 10. 55-83; Risk Anal. 1987. 7. 449-461) and a number of cohort studies (references 4-11 as cited in N Engl J Med. 2009. 360. 376-386).
high income countries, 2.5% of all deaths are attributable to air pollution (
o The American Cancer Society Cancer Prevention Study II has followed a cohort of 1.1 million people since enrollment in 1980, and provides consistent evidence of an association between air pollution and increased mortality (Krewski D et al. Special Report published by the Health Effects Institute in Cambridge MA. 2009).
o The World Health Organization estimated in 2002 that air pollution is responsible for 800,000 premature deaths worldwide each year, which means that means that particulate matter ranks as the 13th leading cause of global mortality. Furthermore, the WHO estimates that 1.4% of all deaths and 0.8% of disability-adjusted life years are the result of particulate air pollution (citations are the WHO web site).

o GOOD NEWS - prospective data in 211 county units in 51 metropolitan areas in the U.S. with matching data on fine-particulate air pollution from the late 1970’s and early 1980’s as well as the late 1990’s and early 2000s shows that reductions in air pollution (i.e. PM10) accounted for as much as 15% of the overall increase in life expectancy in the study areas (N Engl J Med. 2009. 360. 376-386).
· Air pollution and cardiovascular disease
o Biologic mechanism to explain harm - systemic inflammation and oxidative stress lead to increased formation of atherosclerotic plaque (Clin Sci. 2008. 115. 175-187).
o Magnitude of impact of air pollution (specifically particulate matter) upon cardiovascular disease may be greater than magnitude of impact upon pulmonary disease.
o American Heart Association in a scientific statement concludes that overall evidence is consistent with particulate matter playing a causal role in cardiovascular morbidity and mortality (Circulation. 2010. 121. 2331-2378).
o Epidemiologic and observational clinical studies have suggested that exposure to air pollution may worsen the symptoms of angina (Circulation. 2005. 112. 3073-3079), exacerbate exercise induced myocardial ischemia (Circulation. 2002. 106. 933-938; Environ Health Perspect. 2005. 113. 883-887), trigger acute MI (Circulation. 2001. 103. 2810-2815; N Engl J Med. 2004. 351. 1721-1730), and trigger stroke (Stroke. 2005. 36. 2549-2553).
o Short term exposure to particulate air pollution might trigger an acute cardiovascular event (Circulation. 2006. 114. 1863-1872).
term exposure to fine particulate air pollution is associated with an increased
incidence of cardiovascular disease and a 76% increased risk of death from
cardiovascular disease, based on data in 65,893 postmenopausal women in the WHI
observational study (
o Diesel exhaust is an important component of fine particulate matter (Environ Health Perspect. 2000. 108. 941-947); a crossover RCT in 20 men with prior MI who were experimentally exposed to dilute diesel exhaust concluded that brief exposure to dilute diesel exhaust promotes myocardial ischemia and inhibits endogenous fibrinolytic capacity in men with stable coronary artery disease (N Engl J Med. 2007. 357. 1075-1082).
o Short term exposure to fine particulate matter (aerodynamic diameter < 2.5 micrometers) is associated with an increased rate of hospitalization for heart failure, based on analyzing hospitalization data of patients with a diagnosis of heart failure who lived in a well defined geographic area with long term daily monitoring of particulate matter, a substantial temporal variability in the level of fine particulate matter (Am J Cardiol. 2008. 102. 1230-1234).
o Exposure to particulate matter is associated with a significant increase in stroke related mortality (Environ Health Perspect. 2002. 110. 187-191) and stroke hospitalizations (Neuroepidemiology. 2010. 34. 131-142).
A review of medical records of 1705
o A systemic review and meta-analysis of 34 studies shows that all the main air pollutants, with the exception of ozone (i.e. carbon monoxide, nitrogen dioxide, sulfur dioxide, PM10 and PM2.5) were associated with an increase in the risk of ‘near term’ MI (JAMA. 2012. 307. 713-721).
· Air pollution and cognitive decline
o Data in 19,409 US women aged 70-81 years in the Nurses’ Health Study Cognitive Cohort shows that long term exposure to both fine particulate matter (PM2.5) and course particulate matter (PM2.5-10) “at levels typically experienced by many individuals in the United States is associated with significantly worse cognitive decline in older women” (Arch Intern Med. 2012. 172. 219-227).
· Air pollution and risk of deep venous thrombosis (DVT)
o There is data that exposure to particulate air pollution causes hypercoagulability (J Thromb Haemost. 2006. 4. 252-260).
10 year long case control study in
· Air pollution and diabetes - published data supports an association (Lockwood A. Diabetes Care. 2002).
· Air pollution and pulmonary disease
o Numerous epidemiologic studies have shown associations of chronic exposure to particulate matter either < 2.5 micrometers in aerodynamic diameter (PM2.5) or < 10 micrometers in aerodynamic diameter (PM10) with decreased lung function (Am J Respir Crit Care Med. 1994. 149. 1209-1217; Am J Respir Crit Care Med. 1997. 155. 122-129; Am J Respir Crit Care Med. 1998. 158. 289-298; Occup Environ Med. 2004. 61. 350-357) and mortality (N Engl J Med. 1993. 329. 1753-1759; Am J Respir Crit Care Med. 1995. 151. 669-674; Am J Respir Crit Care Med. 1999. 159. 373-382; JAMA. 2002. 287. 1132-1141; Lancet. 2002. 360. 1203-1209; Environ Health Perspect. 2004. 112. 610-615) without evidence of a threshold level.
randomized crossover study in 60 adults with either mild or moderate asthma
showed that exposure to diesel traffic was associated with asymptomatic but
consistent reductions in lung function and these changes in lung function were

o GOOD NEWS - the Swiss Cohort Study on Air Pollution and Lung Diseases in Adults, a prospective study in 9651 adults randomly selected from population registries in 1990 and assessed in 1991 (initial data published Am J Respir Crit Care Med. 1997. 155. 122-129) showed that the decline in overall exposure to air pollution the 8047 participants reassessed in 2002, and specifically to home outdoor PM10 (particulate matter with an aerodynamic diameter less than 10 micrometers) correlated with attenuation of the decline in lung function related to exposure to PM10 (N Engl J Med. 2007. 357. 2338-2347).
Ground pollution and human disease
· Primary biliary cirrhosis prevalence is higher in people living near Superfund toxic waste sites in New York City (Hepatology. 2006. 43. 525-531).
Noise pollution and human health
· Constant low level noise (car and train traffic) is associated with higher release of cortisol while sleeping, based on research in 115 Australian children (J Acoustic Soc Amer. 3/01).
· May lower productivity and motivation, based on data in 40 clerical workers who made fewer attempts to solve a difficult puzzle when working in a noisy environment (J Applied Psychol. 10/00).
· Correlated with an increased risk of MI (Eur Heart J. 2/06). Men living for at least 10 years near streets with heavy traffic were 80% more likely to have a heart attack than those living on quiet streets.
· Noise from intermittent traffic disturbs sleep and worsens mood and performance the next day.
Childhood diseases – the change in prevalence is indicative of a change in the environment
· ADHD diagnosed in 6% of school-age children in 1999 (AHCPR Research Publication 99-0050). There was no entry for ADHD in the American Association Psychiatric DSM until 1968.
· Asthma prevalence estimated at 9% in children and adolescents in 2005, double the prevalence in the 1980’s (Adv Data. 2006. 381. 1-24).
· Brain tumor incidence increased 21% between 1973 and 2003; lymphoma incidence increased 30%.
CATEGORIES OF POTENTIAL POLLUTANTS
· Most contain synthetic fragrances that may emit potentially dangerous phthalates and volatile organic compounds.
· Natural alternatives include a bowl filled with dried sage or thyme, or essential oils.
Air purifiers (Consumer Reports. 5/05. 22-25; 12/07. 48-51; 9/10. 44-46)
· Note according to the EPA, indoor air is 2-5 times more polluted than outdoor air on average.
· Not regulated by the EPA because they are used indoors, and not regulated in 2005 by the FDA because they are not considered medical devices.
· Types of air purifiers
o Ozone - there are ozone air purifiers on the market, but these absolutely should not be used (except by professionals after a fire or a flood), as per Dr. Mercola and Consumer Reports.
o Ionizing – as per www.mercola.com these use a charged plate electrostatic system, but with no fan. It relies solely on the electrostatic plates to move the air though the air purifier. As per Consumer Reports, these tend to produce more ozone than HEPA purifiers.
o Negative ion purifiers – new technology, but as per www.mercola.com 2/06, not proven as effective as HEPA technology or electronic technology when it comes to eliminating and catching more particles in the air.
o HEPA – as per www.mercola.com an air purifier that is equipped with a HEPA filter is able to absorb 99.7% of all particles that are 0.03 microns and larger in size. Most harmful particles found in the air are measured to be about 0.03 microns or larger. To qualify as a "true" HEPA, the filter must allow no more than 3 particles out of 10,000 to penetrate the filtration media. However, pure HEPA air purifiers do not remove odors, chemicals or gasses. Since these are molecular level substances, the 0.3 micron holes are large compared to the gas molecules. Because air must pass through the filter, it can be difficult to clean a very large room with a HEPA filter.
o HEPA combined with a carbon filter (zeolite in the carbon serves as a molecular sieve and as a dessicant).
o Electrostatic - use an electronic charge to attract particles to collection plates and eliminate them from the air. Most create some ozone.
§ One stage system
§ Two stage system
o Photocatalysis – as per www.mercola.com photocatalysis is a process that oxidizes organic odors, germs, and fungi in a room or office -- exactly the same way this occurs in nature. The other part of the process is a catalyst made from Ti02 (titanium dioxide) and other proprietary metals, that when activated, generates hydroxyl radicals and super oxide ions. This system is not an air filter, but an air purifier duplicating nature's own methods of air cleaning and revitalization.
o The voluntary industry standard (Underwriters Laboratories) is that they do not produce more than 50 ppb ozone; many of them failed in this regard (Consumer Reports. 5/05. 22-25).
o There is a growing consensus that 50 ppb is too high an acceptable level of ozone emissions (Consumer Reports. 12/07. 48-51).
o Current methodology for measuring ozone emissions from air purifiers is far from perfect (Consumer Reports. 5/05. 12/07. 48-51)
o CADR (clean-air-delivery-rate) results with a seal issued by AHAM (Association of Home Appliance Manufacturers) are meaningful as per Consumer Reports - values above 350 are excellent and below 100 are poor.
of approval from AAFA (Asthma and Allergy Foundation of America) and Allergy
o Consider whole house models with a filter, especially if using a forced air heating/cooling system.
o Portable air purifiers – bigger is better.

analysis of the 13 studies that reported this association (
2. INTERPHONE study found an increased risk for glioma among adults with heavy cell phone use (cumulative duration of 1640 hours or more). Study limited by recall bias and methodologic issues (Occup Environ Med. 2011. 68. 631-640).
3. A study in Sweden concluded astrocytoma 5 times more common among adults who first used cell phones before age 20 (Int J Oncol. 2011. 38. 1465-1474).
4. CEFALO, a multi-center case-control study reported “No increased risk of brain tumors was observed (in children) for the brain areas receiving the highest amount of exposure (Aydin D et al. J Natl Cancer Inst. E pub 7/27/11). A critique of this study was written by the Environmental Health Trust (www.environmentalhealthtrust.org).
§ Behavioral problems – a survey of 13,159 Danish children found an 80% increased risk for hyperactivity and emotional problems amongst young children who used cell phones and whose mothers also used cell phones during pregnancy (Epidemiology. 2008. 19. 523-529).
§ Infertility – the evidence that RF EMF from cell phones affects sperm quality and quantity in animals and in humans is compelling (PLoS One. 2009. 4. e6446); unknown in 2010 is whether this translates into declines in actual human fertility. Data is suggestive of an adverse effect on fertility, with multiple references provided in the following article (Male infertility linked to cell phone EMF exposure. Holistic Primary Care. Summer 2011).
§ Migraines and vertigo – in a Danish retrospective study, long term cell phone users 10-20% more likely to be hospitalized for migraines and vertigo than people who began to use cell phones more recently (PLoS One. 2009. 4. e4389).
§ Miscarriages – suggestive data (Male infertility linked to cell phone EMF exposure. Holistic Primary Care. Summer 2011).
§ Neurodegenerative disease – theoretical mechanism and anecdotes.
§ Parotid salivary gland tumors – in a nationwide case control study, positive association identified (Am J Epidemiol. 2008. 167. 457-462).
o Cell phone radiofrequency exposure affects brain glucose metabolism – in a randomized, crossover study in 47 healthy participants, “50-minute cell phone exposure was associated with increased brain glucose metabolism in the region closest to the antenna. This finding is of unknown clinical significance” (JAMA. 2011. 305. 808-814 and editorial 828-829).
o Originally developed for the Dept of Defense, and entered the marketplace in the early 1980s without testing for safety.
o Post-market evaluation now under the auspices of the FDA, not the EPA.

· Certified biodegradable is a term that is independently verified (Consumer Reports. 1/08. 6).
· The Leaping Bunny symbol (present on Earth Friendly and Seventh Generation detergents) is independently verified and means that the product has not been tested on animals (Consumer Reports. 1/08. 6).
Construction – LEED (Leadership in Energy and Environmental Design) standards – certified, silver, gold, platinum
· Flame retardant found in electronics, furniture, carpets
· Adverse health effects include permanent learning and memory deficits, hearing defects, and decreased sperm count in animals.
· Industry began phasing out use of this chemical in 2009, upon advice of EPA.
DEET (Consumer Reports on Health. June 2014. Page 10)
· First used by US army and sold to consumers since the 1950s.
· Highly effective
· Safety - a December 2013 analysis of 4000 deet-related calls to poison control centers found that 450 individuals required medical treatment after applying deet, and 2 died.
· Risk seems increased in products with 95% deet or more, seems less in products with 30% deet or less, and testing suggests that products with as little as 15% deet are effective.
Deodorants (Natural Solutions. 8/08. Pgs 36-39)
· As opposed to soaps and shampoos, these cosmetics are not rinsed off, so the chemicals accumulate in the underarm and upper breast.
· Aluminum compounds, found only in antiperspirants, may be absorbed and increase body aluminum levels to an undesirable range.
· Propylene glycol, a penetration enhancer found in many ‘natural’ deodorants too, functions as a penetration enhancer – it can cause skin irritation and can be harmful when combined with other chemicals.
· Triclosan, an antibacterial agent, combines with the chlorine in tap water to form chloroform gas, a potential toxin.
· Steareths are byproducts of a manufacturing process (ethoxylation) that makes harsh ingredients more mild. This same manufacturing process produces carcinogenic 1,4 dioxanes.
· Safe alternatives – see below in this outline ‘Practical Measures to Decrease Exposure…’
· When switching to a safer deodorant, realize that it may take the body a week to readjust, with increased body odor for the transition period. If transitioning from an antiperspirant, dry brushing the underarms with a dry washcloth, and also applying a hot washcloth for a few minutes a day, followed by scrubbing with natural soap, may help to get the glands and pores functioning again.
· Family of chlorinated compounds produced as a by-product of industrial processes.
o Municipal and medical waste incineration
o Production of vinyl and PVC
o Copper smelting
o Chlorine pulp and paper bleaching
· Routes of exposure – ground deposition; can travel 1000 miles from incineration sites.
· Bioaccumulate in fatty tissue; highest levels are found in breast milk.
· Found in beef, pork, dairy products, fish, with extremely high levels in canned meat baby food
Dry cleaning (Consumer Reports. February 2003. Pg 10)
· Traditional processes use a cleaning agent called perchloroethylene (perc), which is a carcinogen in animals and may be a carcinogen in humans. Exposure to perc vapors can cause dizziness, fatigue, headaches, and memory loss. Removing clothes from the plastic bag and letting them air out in the garage minimizes exposure to perc.
· Alternatives to perc
o Carbon dioxide - better results than even conventional dry cleaning. www.hangersdrycleaners.com for locations
o Silicone-based - marketed as Green-Earth cleaning, and results comparable to conventional dry cleaning. www.greenearthcleaning.com for locations.
o Wet-cleaning - recommended by GreenPeace, but results poor, so consider only for clothing you would consider hand-washing.
Food production (The Omnivore’s Dilemna by Michael Pollan)
o 1909 – Fritz Haber, a German chemist, figured out how to “fix” nitrogen, making it useful to living things. Prior to this, all usable nitrogen on earth had been “fixed” by soil bacteria living on the roots of legumes, or by lightning strikes (Pg 42).
o 1947 – there was a huge surplus of ammonium nitrate used during WWII for explosives. The USDA recommended spreading this on farmland as fertilizer to use up the surplus, and subsequently munitions plants switched to producing chemical fertilizer. “The chemical fertilizer industry (along with that of pesticides, which are based on poison gases developed for the war) is the product of the government’s effort to convert its war machine to peacetime purposes.” (Pg 41)
o US farm policy in the 1930s sought to avert overproduction (Pg 49). This policy gradually began to change between the 1950s and the 1970s (Pg 50), then changed significantly with the 1973 farm bill which began a system of payments to farmers to subsidize production, in place of incentives to avert overproduction (Pg 52).
o Replacement of the family farm with CAFOS (concentrated animal feedlot operations).
§ These generate an estimated 575 billion pounds of animal manure yearly, which cannot economically be transported any significant distance, so is stored in lagoons or covered pits, and may contaminate nearby streams and rivers.
§ Antibiotic overuse is a common feature of these operations.
· Petroleum is the source of synthetic fertilizer
o It requires about 50 gallons of oil to raise one acre of corn – this includes the natural gas which is the source of synthetic fertilizer, the fossil fuels used to synthesize the pesticides, and the gas used to plant, harvest, and transport the corn (Pg 45).
o A 1200 pound steer which eats 25 pounds of corn per day will have consumed in a lifetime the equivalent of 35 gallons of oil (Pg 84).
· Farmers have an economic incentive to use excess synthetic fertilizer to increase yield of corn, and the excess either evaporates and contributes to acid rain, or ends up in streams and rivers, and eventually most of it ends up in the Gulf of Mexico, where its “deadly fertility poisons the marine ecosystem” (pg 47) creating “an eight-thousand-square-mile zone so starved of oxygen nothing but algae can live in it” (Pg 83)
· “…as much as a third of all the greenhouse gasses that human activity has added to the atmosphere can be attributed to the saw and the plough.” (Pg 198)
· “…if the sixteen acres now being used to grow corn to feed cows in the United States became well-managed pasture, that would remove fourteen billion pounds of carbon from the atmosphere each year, the equivalent of taking four million cars of the road.” (Pg 198)
· “It’s true that prodigious amounts of food energy are wasted every time an animal eats another animal – nine calories for everyone we consume. But if all that energy has been drawn from the boundless storehouse of the sun, as in the case of eating meat off this pasture, that meal comes as close to a free lunch as we can hope to get. Instead of mining the soil, such a meal builds more of it. Instead of diminishing the world, it has added to it.” (Pg 199)
· “…researchers at the Land Institute have … calculated that in fact more nutrients are produced – protein and carbohydrate – in an acre of well-managed pasture than in an acre of corn.” (Pg 199)
· “… the government did everything it could to help wean cattle off grass and onto corn, by subsidizing the building of feedlots (through tax breaks) and promoting a [USDA] grading system based on marbling that favored corn-fed over grass-fed beef. (The government also declined to make CAFOs [concentrated animal feeding operations] obey clean air and water laws).” (Pg 200)
· “The ninety-nine-cent price of a fast food hamburger simply doesn’t take account of that meal’s true cost – to soil, oil, public health, the public purse… costs … to the taxpayer (in the form of subsidies), the health care system (in the form of food-borne illnesses and obesity), and the environment (in the form of pollution)…” (Pgs 200-201)
· Efficiency – two different definitions (Pgs 214-215)
o Industrial agriculture – yield of one chosen species (monoculture) per acre
o Natural systems – efficiencies flow from complexity and interdependence. One creature’s waste becomes another creature’s lunch. Efficiencies come from mimicking relationships found in nature, and layering farm enterprises on the same land over time. In effect, farming on a plot of land is in 4 dimensions, space and time.
Flaws in the argument that many individuals in
o With food raised on a sustainable farm “…all of the costs are figured into the price. Society is not bearing the cost of water pollution, of antibiotic resistance, of food-borne illnesses, of crop subsidies, of subsidized oil and water – all of the hidden costs to the environment and the taxpayer that make cheap food seem cheap.” (Pg 243)
o As a society, Americans spend about a tenth “…of our disposable income feeding ourselves…down from a fifth in the 1950s. Americans today spend less on food, as a percentage of disposable income, than any other industrialized nation, and probably less than any people in the history of the world.” (Pg 243)
· Occupational exposure to formaldehyde (in manufacturing or in funeral industry) associated with increased death rates from myeloid leukemia (J NCI. 2009. 101. 751-761 and 1696-1708).
· Widely used in construction materials, manufacturing, consumer products, and in funeral industry.
Glyphosate (Roundup) [Editorial. Campbell AW. Altern Ther Health Med. 2014. 20. 9-11).
· Most widely used herbicide in the world (Pest Manag Sci. 2000. 56. 299-308).
· Originally patented as a chelating agent, wetting agent, and biologically active compound used as a descaling agent to clean out mineral deposits in plumbing pipes, boilers, and heaters; later patented as a herbicide and marketed under the name of Roundup in the 1970s.
· Considered safe because it is water soluble and thought to be readily degraded into a nontoxic degradation product, but
o Detectable in the urine of farm workers, and residues detectable in many foods.
o Recent studies have demonstrated toxicity, including DNA damage (Arch Toxicol. 2012. 86. 805-813), disrupts aromatase (Environ Health Perspect. 2005. 113. 716-720), suppresses CYP 450 enzymes and amino acid synthesis by the gut microbiome (Entropy. 2013. 15. 1416-1463), and may cause toxic nephropathy (Int J Environ Res Public Health. 2014. 11. 2125-2147).
o Residues in food may inhibit CYP450 enzymes, compromise vitamin D3 activation, and chelate iron.
· While it does not directly damage human tissue, it does inhibit microbial production of tyrosine, tryptophan, and methionine, building blocks for neurotransmitters, and thus adversely affect the microbiome (beneficial bacteria) in the human gut
· 35 metals are of concern due to occupational or residential exposure to potentially toxic doses
o 23 of these are "heavy metals": antimony, arsenic, bismuth, cadmium, cerium, chromium, cobalt, copper, gallium, gold, iron, lead, manganese, mercury, nickel, platinum, silver, tellurium, thallium, tin, uranium, vanadium, and zinc.
o "Heavy metals" are defined as chemical elements with a specific gravity at least 5 times the specific gravity of water.
· In small amounts, some of these metals are common in our environment and diet, and even necessary for health.
o Copper, iron, manganese, and zinc are heavy metals which are necessary for life – they are referred to as trace elements.
o Mercury occurs naturally in the crust of the earth; ~50% of environmental mercury is ‘natural’ in origin and ~50% is released from human activities (coal-fired plants, waste incineration, dental industry).
• Heavy metal toxicity can result in damage to the nervous system, cardiovascular, hematopoietic, immune system, lungs, kidneys, brain, liver, other vital organs, and cancer.
• Long-term exposure may result in slowly progressing physical, muscular, and neurological degenerative processes that mimic Alzheimer's disease, Parkinson's disease, muscular dystrophy, and multiple sclerosis.
• Ways to reduce exposure to heavy metals – see ‘Practical Measures’ below
• Lead test kits – see Consumer Reports 9/08, pgs 43-44 for ‘easy to use’ kits
Insect repellants – see DEET
· Compact fluorescent light bulbs (CFLs) use 75% less energy and last 6-10 times longer.
o The downside is that they do contain a trace of mercury. HOWEVER, the major source of mercury in the environment today is coal-fired power plants, so by reducing the demand for electrical power from coal-fired power plants, fluorescent bulbs actually may decrease the environmental burden caused by mercury (Janet Brown. Holistic Primary Care. Winter 2007).
o Due to the mercury content, it is best to discard fluorescent bulbs as hazardous waste, rather than in the trash – go to www.epa.gov/bulbrecycling.htm for a recycling site near home. As of 2011, Home Depot, Ikea, Lowe’s, and some Ace and True Value stores allow consumers to drop off used bulbs for recycling.
o If the bulb breaks, open a window, leave the room for 10 minutes, wear disposable gloves, brush the broken pieces into a sealable plastic bag, wipe up using a damp paper towel, and put plastic bag in the trash. Don’t vacuum, as this can disperse the mercury. More information at www.epa.gov/mercury/spills.
o Some bulbs produce a yellow light (labeled ‘soft’ or ‘warm’) whereas some produce a white light (labeled ‘bright white’ or ‘natural’ or ‘daylight’).
o Potential safety issues with CFLs
§ Most light bulbs contain ~1% of the amount of mercury in a mercury thermometer - www.gghc.org provides information on the mercury content of different brands, as the content does vary from brand to brand.
§ All fluorescent bulbs “flicker.” The flicker is not visible, but with AC voltage, the luminance of the bulb changes 120 times per second, fluctuating between full light output and total darkness 120 times per second. This fluctuation creates an electromagnetic field, and the effect of this electromagnetic field on human physiology is unknown. A 10 watt fluorescent tube may produce a magnetic field at least 20 times greater than a 60 watt incandescent bulb (Wikipedia).
· Light emitting diode bulbs (LEDs) contain no mercury and use less energy than CFLs, and have an estimated 18-46 year life span. EXPENSIVE in 2011.
· Products (Time 8/3/09 and extensive ratings Consumer Reports 10/10 pg 29)
o Lennis’ Pharox LED – lifetime of 25 years, cost of $50 per bulb
o Earthmate’s Super Mini-Size CFL – contains 80% less mercury than standard CFLs, lifetime of 10,000 hours, cost of $3.50 per bulb
o Philips’ T60 Halogena is an incandescent which uses 30% less energy than traditional incandescents, lifetime of 3000 hours, $5 per bulb
· Medical waste incineration was the single largest source of dioxin air pollution.
· In 1997 medical waste incinerators were the fourth largest source of man-made mercury emissions.
· Hospitals also contribute to mercury in the water supply and landfills (mercury thermometers, mercury BP cuffs, fluorescent lights)
· In 2005, over 6000 medical waste incinerators have shut down, and mercury emissions from medical waste incinerators has been reduced by 99%!
· Hospitals for a Healthy Environment (H2E) was formed in 1998 when the EPA and American Hospital Association (AHA) signed a Memorandum of Understanding to address serious environmental issues. The group is now a collaborative effort between the EPA, AHA, American Nurses Association, and nonprofit coalition Health Care without Harm (www.noharm.org).
· Trace levels of multiple medications are now measurable in municipal water supplies - repercussions in terms of human health, in particular with regard to antibiotics and estrogenic medications are uncertain.
· Federal guidelines for drug disposal suggest mixing unused medication with coffee grounds or cat litter, placing in a sealed container, and throwing out with the trash (except for some controlled substances, which the government still recommends flushing down the toilet, as of 2008).
· Some pharmacies have take-back programs for unused medications.
· These are plastic particles, less than 5 mm in size, often added to facial cleaners, soaps, cosmetics, and toothpaste.
· They are too small to be captured by sewage treatment plants.
· They do not decay, and accumulate toxins on their surface.
· The beads are eaten by fish and wildlife, and cause harm.
· If microbeads are in a product, words such as polyethylene or polypropylene will appear in the ingredients list.
· Mycotoxins can overload detoxification mechanisms in the liver, affect the immune and nervous systems, and lead to multiple chemical sensitivities.
· Trichothecenes are a very bad group of mold toxins.
· If mold in the home is suspected as the cause of symptoms, leave the home for 5 days and acquire new clothing not washed in the home, to see if symptoms improve.
Nanotechnology (Consumer Reports. Investigative Report. 7/07. 40-45)
· This involves technology which reduces particles to nanometers in size, and it does offer tremendous potential in the areas of (1) health and medicine, (2) energy and the environment, and (3) consumer products.
· The characteristics of materials changes at the nanoscale benign materials can become toxic, because microscopic particles may react more readily with human tissue.
· There is concern that nanomaterials may linger in the environment and damage the ecosystem.
· Traditional safety assessment methods are not adequate for nanomaterials; very little money has been spent on risk assessment.
· In 2007, the FDA is not involved in assessment of nanoingredients, and labeling of products which have nanoingredients is not mandatory.
· Even though there is no mandate to disclose whether a consumer good has nanoparticles in it, the Project on Emerging Nanotechnologies maintains a database of hundreds of nano-based products ranging from socks to car wax – www.nanotechproject.org/inventories/consumer.
· Chemical used in cosmetics, found in sunscreen, lip balm, moisturizers.
· Potential health hazards include hormone disruption and low-birthweight babies.
· In the upper atmosphere ozone is good - it shields us from harmful ultraviolet rays.
· In the air we breathe, ozone is a free radical and an irritant detrimental to human health.
· EPA standard for outdoor air is less than 80 ppb averaged over 8 hours; there is no EPA standard for indoor air.
· A recent study has shown a link between death rates and average ozone concentration, even below 80 ppb.
· Asthmatic children have been shown to experience worse symptoms and require more rescue medication as a function of ozone levels between 60-80 ppb.
· Synthetic preservatives found in personal care products (moisturizers, shaving products)
· Causes hormone disruption and cancer in animals.
PBDEs (polybrominated diphenyl ethers) – part of a class of brominated flame retardants (BFRs)
· Levels of PBDE flame retardant in U.S. blood samples have risen sharply over the past three decades, based on measurement in frozen 1973 samples (J Occup Environ Med. 2005. 47. 199-211). Blood levels of flame retardant are higher in the U.S. than any other country.
· Potential effects on human health are unknown; toxicological studies show that these compounds are neurotoxins, carcinogens, and endocrine disruptors.
· PDBEs have properties similar to PCBs and dioxins.
· PDBEs are found in fabrics, upholstery foam, carpets, insulating material, and electronic devices
· Countries that have banned synthetic flame retardants have noted falling levels in humans.
· Ikea furniture and mattresses don’t contain PDBE’s
· A study of 37 pesticides in use currently examined which of these demonstrated in vitro androgen receptor antagonism. All 14 pesticides with previous evidence of androgen receptor antagonism were confirmed as antiandrogenic, as were 9 previously untested pesticides. In addition, 7 compounds were classified as androgenic (Environ Health Perspect. 2011. 119. 794-800).
· Pesticides and cancer – “a growing body of epidemiological, molecular biology, and toxicological evidence assessing the link … between specific pesticides and specific cancers is becoming available in the scientific literature.” The link is present for those applying the pesticides as well as those exposed to the pesticides. Data shows a link with breast cancer, prostate cancer, leukemia, multiple myeloma, and non-Hodgkin lymphoma (CA Cancer J Clin. 2013. 63. 120-142).
· Very resistant to degradation; carcinogenic in animals
· Found in carpeting, clothing, and furniture labeled as stain resistant
· Found in non-stick cooking pans and some waxed dental floss
· Found in some cosmetics, such as nail polish, eye makeup and facial moisturizers.
· Component of Teflon found in nonstick pots and pans.
· Human studies show evidence of hormone disruption and reproductive abnormalities.
· EPA is urging manufacturers to stop using by 2015.
· Types of plastics (NOTE the numbers on the bottom of plastic are resin ID codes for sorting for recycling, and don’t always correlate with the type of phthalate in the product. #7 means ‘other plastics’ and includes products with the harmful BPA as well as products with less harmful plastics)
o Bisphenol A (BPA) - AVOID.
§ A chemical used in plastic production since the 1940’s to harden polycarbamate plastics and make epoxy resins.
§ Primary route of exposure in humans is oral ingestion, but also some transdermal exposure an inhalation of BPA in dust.
§ Most is excreted within a few days of exposure, but exposure is often constant, and very small amounts in the blood have biological effects – even though the EPA has set the lowest observed adverse effect level at 50mg/kg/day, a study showed effects of BPA on the testes, prostate, ovaries, and breast tissue at levels lower than 1 ppb (full report at www.endocrinedisruption.com/endocrine.TEDXList.overview.php).
CDC found BPA in the urine of 95% of 394
individuals tested (Environ Health Perspect. 2005. 113. 391-395); NHANES 2003-2004 found
BPA in the urine of >90% of the
§ Most claims for human safety are based on extrapolation from rodent-based toxicology models, but the relevance of this model to humans is unclear. In addition, a growing body of animal studies demonstrates neurological (i.e. inattention), reproductive (i.e. breast and prostate cancers), and metabolic abnormalities (i.e. diabetes, obesity) at very low levels of exposure, comparable to human exposures.
§ Found in many sturdy, hard plastic items, as it is present in epoxy resins lining food and beverage containers (often labeled at #7).
1. Common sources include (hard) water bottles, baby bottles, food containers (such as those labeled microwavable), canned food (it is in the resin lining the cans), utensils, carbonless paper used for receipts, compact discs, and dental sealants.
2. More than 2 million metric tons produced in 2003, with an annual increase in demand of 6-10% (Eur Chem News. 2003. 78. 17).
§ Adverse health effects (Editorial. Ann Intern Med. 2011. 155. 392-393).
1. BPA is a xenoestrogen – while dose needed to stimulate breast cell cancer growth is 100,000 times higher than estradiol, there is some data that BPA acts similarly to the synthetic estrogen, DES. Furthermore, animal data shows that the active metabolite of BPA is more estrogenic than the parent compound.
2. BPA has antiandrogenic activity in men, and alters the ratio of estradiol to testosterone in a manner which indicates decreased aromatase activity in those men with exposure – data derived from single urine measurement of BPA and multiple serum hormone level measurements in 167 men recruited from infertility clinics (Environ Sci Technol. 2010. 44. 1458-1465).
3. Accumulating evidence indicates that BPA exposure (1) increases the risk of breast cancer and (2) can interfere with chemotherapy for breast cancer.
4. Cross sectional data in 1455 adults in NHANES 2003-2004 found that higher BPA exposure, as reflected by higher urinary concentrations of BPA-monoglucuronide, were correlated with an increased risk of cardiovascular disease, type II diabetes, and elevated liver enzymes (JAMA. 2008. 300. 1303-1310 and editorial 1353-1355).
NEGATIVE STUDY – a cross-sectional study of 3423 adults
6. The potential role for BPA in the pathogenesis of human obesity is controversial (in 2011).
Products containing this banned in
In 11/06, 38 scientists met at
§ BPA may be safer in humans than rodents, as there is data the BPA glucuronide in humans is excreted in the urine, and thus not subject to enterohepatic recirculation, whereas BPA in rodents is excreted in the feces (Letter written by Exec Director American Dental Assn)
o Polystrene – labeled #6, found in many foam containers and cups, some clear disposable takeout containers, some plastic cups. May leach styrene, a possible carcinogen. AVOID.
o Polyvinylchloride (PVC) – labeled #3, found in many plastic wraps for grocery store food, cause birth defects in mice. AVOID.
o DEHA – AVOID.
o Polyethylene terephthalate (PET or PETE) – labeled #1, safer, found in soft drink and water bottles
o High-density polyethylene (HDPE) – labeled #2, safer, found in milk and water bottles.
o Low-density polyethylene (LDPE) – labeled #4, safer, found in wrapping films and grocery bags.
o Polypropylene (PP) – labeled #5, safer, found in yogurt containers and syrup bottles.
o NOTE #7 means ‘other plastics’ and includes products with the harmful BPA as well as products with less harmful plastics.
· Categories (types) of plastics
o Thermoplastics – soft when heated, harden when cooled. AVOID, as this category emits toxic vapors. Examples of thermoplastics – vinyl chloride, PVC, acrylic plastics
o Thermosets – begin as soft plastics; when heated, shape is set. Safer than thermoplastics, as they don’t off-gas. Exceptions are urea-formaldehyde used in building materials, and polyurethane foam used in furniture and pillows.
· Sources of phthalates (one of many chemicals in plastics) – average daily intake estimated at 3 mg
o Children’s toys and children’s care products (i.e. infant formula, pacifiers) - several banned in legislation enacted 8/08.
o Clothing – polyester is plastic
o Dental materials (i.e. composite fillings, crowns).
o Food packaging (water bottles, plastic food wraps) – there is data that the phthalates actually migrate from the plastic wrap or plastic bottles or Styrofoam cups into the food or water, and are thus consumed
o Household items- particle board, plywood, polyurethane foam in furniture and pillows, Styrofoam cups, Teflon pans, vinyl floors, vinyl in shower curtains
o Intravenous lines and bags.
o Medications - may be present in as many as 47 medications; phthalate metabolite levels higher in people taking didanosine (for HIV), mesalamine (for IBD), omeprazole (for GERD) and theophylline (for asthma).
o Nail polish, cosmetic products, body lotions and gels, shampoos, deodorants, glues, detergents, insect repellants
o PVC pipe
· Effects of phthalates in humans
o Endocrine disruptors - phthalates found in the serum of 68% of girls with premature breast development and in 3% of age-matched controls (Environ Health Perspect. 2000. 108. 895-900).
o Lower testosterone
o Lower thyroid activity (but do not alter lab test values).
o Increase cell proliferation in breast cancer tissue and inhibit tamoxifen-induced apoptosis (J Toxicol Environ Health. 2004. 67. 2025-2035)
o Poison peroxisome proliferator-activated receptors (PPARs), which are nuclear receptors that are lipid-activated and control genes for metabolism, lipid homeostasis, inflammation, immune function, amongst other functions.
o Predispose to atherosclerosis – a study in which 1016 participants, all age 70, underwent carotid ultrasound and had blood levels measured for BPA and 10 phthalates showed that the phthalate metabolite MMP was related to atherosclerotic plaques in the carotid arteries, independent of conventional CV risk factors (Atherosclerosis. 2011. 218. 207-213).
· Detoxification of phthalates
o Chelation is ineffective.
o Sweat is the only proven mechanism for removing phthalates
o Probably eliminated via glucuronidation pathway (Phase II) and this can be supported by intake of indoles (cruciferous vegetables) and calcium-D-glucarate.
POPs (Persistent Organic Pollutants) [Editorial. Pizzorno J. IMCJ. 2013. 12. 8-10)
· Definition – “organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes.” Resistance to breakdown results in bioaccumulation in humans and in animal food chains.
· Categories – industrial chemicals, pesticides, plasticizers, solvents.
· Dirty Dozen POPs (WHO – 1995) – Aldrin, chlordane, DDT, dieldrin, heptachlor, hexachlorobenzene, mirex, polychlorinated biphenyls, polychlorinated dipenzo-p-dioxins, polychlorinated dipenzofurantoins, and toxaphene. Since then, additions to the “dirty dozen” include carcinogenic polycyclic aromatic hydrocarbons, brominated flame retardants, and some organometallic compounds.
· Chemical characteristics of POPs
o Low water solubility
o High lipid solubility
o High molecular masses (those with lower masses are less toxic)
o Frequently halogenated – the more chlorine groups, the more resistant to degradation
· Physiological effects
o Cardiovascular Disease
o Neurologic Dysfunction - ADHD

Precautionary thinking – premises (Ted Schettler, MD AHMA Annual Meeting 6/07)
· We have an obligation to prevent harm to the commonwealth
· Values and ethics are essential to decision making
· Science can provide guidance but not the whole answer
· Uncertainty and surprise are intrinsic to a complex world
· Government has a key role to play
· Some things are more important than money
· We hold the commonwealth in trust for future generations
· Prevention is wiser, fairer, and less costly than repairing damage
Practical measures to decrease the exposure to environmental toxins and EMF pollution
· Be aware of sources of indoor air pollution – these include gas appliances, air fresheners, aerosol sprays, moth crystals, stored paints and solvents, gardening chemicals and pesticides, bottles of perfume and household cleaning products, incense.
o Avoid canned meat baby food, due to extremely high levels of dioxins in these products.
o Born Free Baby bottles –
· Food - eat organic, and ideally pasture fed meat and poultry and wild fish
o A study in children found that “the median urinary concentrations of the specific metabolites for malathion and chlorpyrifos decreased to the nondetectable levels immediately after the introduction of organic diets and remained nondetectable until the conventional diets were reintroduced” (Environ Health Perspect. 2006. 114. 260-263).
o At the very least, avoid the fruits and vegetables at the top of the list of those most ‘contaminated’ with pesticides – for an updated list, go to http://www.foodnews.org/, ‘Food News from the Environmental Working Group’ and scroll to the bottom of the page for a ranking for fruits and vegetables with the most to the least amount of pesticide residue. This list is periodically updated.
o www.vitalchoice.com for wild salmon.
o Pasture raised meat and poultry (free range does not necessarily mean that the animals feed on grass as opposed to corn meal)
o Community supported agriculture - Porter Farms - 757-6823
house plants have been found to remove a variety of toxins (i.e. formaldehyde,
VOCs), based on data gathered by NASA, using plants in sealed test chambers
(i.e. Biohome). Ten of the most efficient plants at
removing toxins are
o Spider plant removes carbon monoxide
o Peace lily removes benzene (found in dry-cleaned clothing and oil-based paints).
o Draceana removes trichlorethylene (released by photocopiers and printers).
o Areca palm removes toluene (found in nail polish, perfume, permanent markers).
o Carry water in stainless steel or glass bottles; avoid bottled water in plastic bottles and avoid Nalgene hard plastic water bottles, as most contain bisphenol A. Two sources of stainless steel bottles are www.GreenFeet.com and www.isabellacatalog.com.
o Consider a water filter for home use – for information on the different categories of filters, go back to the Home Page and scroll down about ¾ of the way in the ‘Nutrition’ outline.
o Consider a portable water filter for travel – one such unit is the Trav-L-Pure unit available at www.purewaterplace.com.
