"Industrial chemicals have no place in our bodies. Moreover, there are far too many people -- too often people of color and poor people -- who suffer disproportionately from environmental pollution. Now we know we're getting it from inside our homes as well as outside. We refuse to be guinea pigs in a massive, uncontrolled experiment, especially when a few people are making a lot of money off selling products that have these toxics in them."
Payton Wilkins, 18, is a senior at Consortium College Preparatory Academy in Detroit, and his favorite subjects are literature and gym. He enjoys painting, and was a member of the youth team that painted the mural at the new Boll Family YMCA in downtown Detroit. Payton coordinates Youth on Patrol Against Pollution under Detroiters Working for Environmental Justice (run by his mother). He aspires to become an entrepreneur and to develop and expand his artistic interests, which include acting. We found four phthalates and seven PBDEs in Payton’s body, as well as bisphenol A in his urine.
"I just turned 18 and it's simply not fair that my body has already built up toxic chemicals. I want to live a healthy long life. I've got things to do and places to go. But what are my chances when I've got these chemicals that are known to be toxic in my body? It pisses me off even more to think that I've been soaking up chemicals from the incinerator all my life. What is all this going to do to me?"
Laura Varon Brown, 46, developed and edits “Twist”, a Sunday newsmagazine of the Detroit Free Press for and about women. Her prior work for the Free Press – where she has worked since 1990 – includes serving as Metro Editor. She has a certificate in Journalism Law from the Detroit College of Law. Above all, she believes that what matters most is motherhood. Ms. Varon Brown – of no relation to Rep. or Bryan Brown - lives in Bloomfield Township with her husband and three children. We found four phthalates and seven PBDEs in Laura’s body, as well as bisphenol A in her urine. "I came into the project a bit of a skeptic about toxic chemicals and the role they play in our every day products and environment. I am really hoping that the awareness this report brings will lead to better disclosure of what's in our containers, furniture and the goods we use every day. Environmental concerns span much deeper than recycling and the gas mileage. That was the biggest eye-opener for me."
Terry Brown, 48, was elected State Representative from Michigan's 84th District in 2006. His prior work includes serving as principal/supervisor of a school for children with significant cognitive, emotional and/or behavioral issues. Rep. Brown also worked for many years as a school social worker. He helped promote Michigan's use of renewable energy. He enjoys hockey, hunting, fishing, and scuba diving, and has served on the Huron Sheriff Department's rescue team. He lives in Pigeon with his wife Carol, their son Bryan Brown, and two older children. We found four phthalates and nine PBDEs in Terry's body, as well as bisphenol A in his urine. Given his high BDE-154 reading (which can indicate either BDE-154 or polybrominated biphenyl (PBB) 153), Terry is one of two project participants likely to have been exposed through eating food contaminated with PBB-153 added to feed grain in the early 1970s.
"Showing the prevalence of potential toxins in our bodies illustrates the importance of conducting high-quality research on chemicals before releasing them into our environment. Research and regulations need to work hand in hand to ensure that chemicals are used safely and effectively."
Bryan Brown, 12, is an honors student in 7th grade in Pigeon, Michigan and the youngest of three siblings. He enjoys science class, reading, computer and video games, as well as team sports, boating, and swimming. Bryan's school stands out for having three large wind turbines that have already saved the school thousands of dollars. We found four phthalates and nine PBDEs in Bryan's body, as well as bisphenol A in his urine. Bryan and his father, Terry, are the only two participants in whom we found BDEs 85 and 138, indicating a common source of exposure.

In the current Is It In Us? - Toxic Trespass, Regulatory Failure & Opportunies for Action project, thirty-five people, five from each of seven states, were tested for three groups of common industrial chemicals that are under increasing scrutiny for their contributions to a growing epidemic of diseases and disorders. Blood and urine samples from each participant were tested for: phthalates, which are plasticizers commonly used in cosmetics and plastics; polybrominated diphenyl ethers (PBDEs), which are used as flame retardants in furniture, mattresses, and electronics; and bisphenol A, a chemical used in some plastic water bottles and as a liner in tin cans. Please see the accompanying document for more information on these chemicals and their health effects. In Michigan, Is It In Us? was coordinated by the Michigan Network for Children’s Environmental Health, a coalition of health professional, health-affected, environmental organizations, and others dedicated to a safe and less toxic world for Michigan’s children. The Network seeks to protect Michigan’s children from adverse impacts caused by exposure to widespread hazardous chemicals. The purpose of Is It In Us? is to raise awareness about the presence of industrial chemicals in each of us. The results will help demonstrate the need for new policies in Michigan to reduce our exposures to these chemicals. The goals of the project include:
We all have industrial chemicals stored in or passing through our bodies – the result of over five decades of intensive chemical use in industrialized nations. Most chemical exposures occur without our knowledge from low-level contamination in our food, air, water and the things we touch. Increasingly, biomonitoring is being conducted by national and state agencies and by public interest organizations to assess trends in chemical use and exposure, to identify vulnerable populations and populations exposed to chemicals of concern, to assess the effectiveness of current chemical regulations, and to demonstrate the need for chemical policy reform. Biomonitoring takes a "snapshot" of chemical exposures that could cause health problems. Although individual biomonitoring data in general is not predictive for individual health outcomes, biomonitoring can tell us what environmental chemicals are present in a person’s body at a particular moment in time. Some of these chemicals pass through the body quickly and may be eliminated within a few hours’ time. Others may be persistent and may remain in the body for decades.

Phthalates in Our Bodies In the 2005 CDC study, phthalates were once again widely detected in human urine samples with an increased sample size of over 2,500 Americans. Overall, the study indicated that, with the exception of MEP (mono-ethyl phthalate, the urinary metabolite of DEP), children age 6 to 11 years of age excreted higher concentrations of phthalate metabolites than the older age groups. In the same report, researchers found that women had higher levels of MEP, MBP (mono-butyl phthalate, a urinary metabolite of DBP), MBzP (mono-benzyl phthalate, the urinary metabolite of BzBP), and three urinary metabolites of DEHP: MEHP (mono-2-ethylhexyl phthalate), MEOHP (mono-(2-ethyl-5-oxohexyl) phthalate), and MEHHP (mono-(2ethyl-5-hydroxyhexyl) phthalate). In a more recent study, the phthalate monoesters MEHHP, MEOHP, and MEP were found to be present in 100% of 90 girls age 6 to 9, and MBP, MBzP, and MEHP were found in over 94%. How Are We Exposed to Phthalates? Individual phthalates have various routes of exposure:
What Does Phthalate Exposure Mean For Our Health? Reproductive and Developmental Effects: Phthalate exposure can begin in utero and in one study is strongly associated with a shorter pregnancy duration. Another study also found that prenatal phthalate exposure at environmental levels is associated with altered male reproductive development in humans, including shortened anogenital distance (signifying feminization), an increased likelihood of testicular maldescent, small and indistinct scrotum, and smaller penile size. Later research documented altered male reproductive hormone levels in baby boys most highly exposed to phthalates in their mother's breast milk. Phthalate exposure has also been linked to lower sperm counts, reduced sperm motility, and damaged sperm in men. Respiratory System: Studies have shown concentrations of phthalates in house dust are associated with asthma and rhinitis in children. Exposure to PVC flooring containing phthalates has also been linked to increased bronchial obstruction during the first two years. In adult men, exposure to certain phthalates has been linked to reduced lung capacity at magnitudes similar to those observed with tobacco smoke. Effects in Laboratory Animals: Depending on the exposure level, exposure to DEHP resulted in observed effects on the pituitary, thyroid, thymus, ovaries, testes, lung, kidneys, liver, and blood.

What Is Bisphenol-A? How Are We Exposed to Bisphenol-A? Bisphenol-A in Our Bodies Although the United States Environmental Protection Agency (EPA) considers exposure to 50 µg/kg/day of bisphenol-A safe, this standard was set in 1993 and is based on studies from the 1980s. Currently, there is controversy over effects of bisphenol-A on human health. In August 2007, over 30 scientific experts on bisphenol-A, known as the Chapel Hill panel, published a consensus statement in the peer-reviewed journal Reproductive Toxicology, stating significant evidence indicates adverse health effects occur in animals at levels within the range of exposure that is typical for humans living in developed countries. Later that month, a separate panel of scientists in the U.S. National Toxicology Program’s Center for Environmental Risks to Human Reproduction (CERHR) concluded they have “minimal concern” about the role of bisphenol-A in human reproductive effects, and “some concern that exposure to Bisphenol A in utero causes neural and behavioral effects.” While this statement by the CERHR panel makes it the first government panel in the world to declare that bisphenol-A is not safe, its conclusions nevertheless differ drastically from the Chapel Hill panel in degree of concern. Adding to the controversy are considerations that the CERHR panel excluded from review many peer-reviewed scientific studies and relied heavily upon an industry-funded study that had not been peer reviewed. In one of the reviews of scientific literature excluded by the CERHR panel, researchers found numerous studies indicate a wide range of health effects from exposure to bisphenol-A at significantly lower doses (as low as 2 parts per billion in some studies) than considered “safe” by the EPA. What Does Exposure to Bisphenol-A Mean for Our Health? Since summer 2005, over 130 studies have examined the low dose effects of bisphenol-A. As a result, bisphenol-A has been linked to the following effects: Endocrine disruption: As early as 1936, bisphenol-A was shown to be an environmental estrogen. Compared with natural estrogen, bisphenol-A is a less potent activator of the classic estrogen receptor, but in recent years it has been recognized that “BPA is equipotent with estradiol in its ability to activate responses via recently discovered estrogen receptors associated with the cell membrane,” as found in several studies on cell culture and laboratory animals. In addition to being shown to bind to estrogen receptors, evidence suggests that bisphenol-A also can cause alterations is endogenous hormone synthesis, hormone metabolism and hormone concentrations in blood. Exposure to bisphenol-A has been shown to cause changes in tissue enzymes and hormone receptors as well as interacting with other hormone-response systems. Recurrent miscarriage: Researchers found that women with a history of recurrent miscarriage had average blood serum levels of bisphenol-A at 2.59 ng/ml, more than three times higher than women with successful pregnancies, a finding predicted by previous animal studies. Altered mammary gland development: In a laboratory study, mammary gland development was significantly altered in mice exposed to 250 ng BPA/kg bw?d of bisphenol-A, the lowest dose thus far shown to disrupt animal development. Scientists suggest that this study’s implications for human health include increased susceptibility to breast cancer after perinatal exposure to bisphenol-A. Prostate cancer: Research using cell cultures showed that a concentration of bisphenol-A of 1 nM made prostate cancer cells less responsive to the hormone treatment used to control prostatic adenocarcinomas into remission. Whether this cell culture impact also occurs in people is uncertain, but the concentration is lower than the average level of bisphenol-A found in Americans, as reported by Calafat et al. in 2005. Altered brain development and behavior: Scientists found that bisphenol-A exposure in the womb modifies sexual differentiation of the brain and behavior in rats at only 30 µg/kg/day, lower than the dose considered safe by the EPA. For some behaviors tested, results suggest that bisphenol-A exposure was linked to both demasculinization of males and defeminization of females. Insulin resistance: A recent study in adult mice provided evidence of an association between bisphenol-A exposure and increased risk of type II diabetes, hypertension and dyslipidemia. In this study, scientists found that chronic exposure to low doses of bisphenol-A yields insulin resistance in adult mice. Doses used in their experiments were 5 times lower than the dose considered safe by the EPA. Developmental origins of adult health and disease: The 2007 “Chapel Hill Bisphenol A Expert Panel Consensus Statement: Integration of Mechanisms, Effects in Animals and Potential to Impact Human Health at Current Levels of Exposure” states that enough evidence exists to suggest that adverse health outcomes may not become apparent until after exposure during critical developmental periods has happened. Especially of concern is that “these developmental effects are irreversible and can occur due to low-dose exposure during brief sensitive periods in development, even though no BPA may be detected when the damage or disease is expressed.” Reducing Our Exposure

What Are PBDEs? PBDEs are also part of a broader chemical class called polyhalogenated aromatic hydrocarbons (PHAHs) which include other highly toxic chemicals such as PCBs and dioxins. PBDEs are intrinsically hazardous because of their chemical characteristics: (1) they are stable, meaning that they are persistent in the environment and do not break down easily; How Are We Exposed? PBDEs in Our Bodies What Does Exposure To PBDEs Mean For Our Health? Developmental Effects: Studies in rodents indicate that neonatal exposure to PBDEs permanently affects learning and memory functions, impairs motor activity, and is linked to aberrations in spontaneous behavior and hyperactivity that seems to be permanent. However, it is not known what the developmental effects are in people or at what doses they occur. Reproductive Effects: PBDEs have been correlated to cause cryptorchidism, or undescended testes in new born boys, and permanently impair sperm development in rodent studies. They have also been associated with the delay of puberty in both male and female rodents and alterations in sexual development and gender-specific sexual behavior. Exposure to PBDEs has also been linked to birth defects, reduced weight gain during pregnancy, changes in ovary cells, and reduced sperm count. Cancer: Once study suggests that in utero exposure to PBDE concentrations is associated with an increased risk of testicular cancer in men. The Agency for Toxic Substances and Disease Registry (ATSDR) lists deca-BDE as a possible human carcinogen based on the development of liver tumors in rats that were given the substance. Thyroid Problems: Recent animal studies have shown that PBDE exposure is linked to decreased circulating concentrations of thyroid hormone and to a decrease in thyroid weight in adult rodent offspring.
