Polluted bodies

Ruth Rosen

WHEN MICHAEL LERNER volunteered to give blood and urine samples to medical researchers, he figured they'd only find a few chemicals in his body. After all, Lerner, the president and founder of Commonweal, a health and environmental research institute in Marin County, has lived in Bolinas for 20 years, eaten a healthy diet and avoided exposure to industrial chemicals.

He was wrong. Researchers found his body polluted with 101 industrial toxins and penetrated by elevated levels of arsenic and mercury.

Scientists call such contamination a person's "body burden."

Lerner was one of nine people -- five of whom live and work in the Bay Areas -- who were tested for 210 chemicals commonly found in consumer products and industrial pollution. Mt. Sinai School of Medicine in New York, the Environmental Working Group of Oakland and Washington, and Commonweal collaborated on this innovative study of the body burden.

At press conferences held in San Francisco and Washington, D.C., last week, researchers revealed these shocking results: On average, each person had 50 or more chemicals linked to cancer in humans and lab animals, considered toxic to the brain and nervous system or known to interfere with the hormone and reproductive systems. (The Environmental Working Group's Web site www.ewg.org/reports/bodyburden/ (or click here) features biographies and toxic profiles for each person as well as the kind of products that contain such chemicals.)

Lerner was astounded. "Being tested yourself brings the body burden home in a very personal way." For years, he has lived with a condition that causes a hand tremor. Now he suspects why. "Mercury and arsenic both cause tremor, so I've stopped eating all fish that have high mercury levels."

Lerner's wife, Sharyle Patton -- co-director of the Collaborative on Health and Environment -- also participated in the study. To her surprise, the Bolinas resident had as many toxins as people who have lived in cities. In fact, she had the highest levels of dioxins and PCBs -- both highly toxic substances -- of anyone in the test group. "What we learned," says Patton, "is that we all live in the same chemical neighborhood."

Lerner, who has devoted his life to promoting the health of people and the planet, hopes that such bio-monitoring tests will become routine and affordable. "Body burden tests," he says, "are the thermometer that gives us our body's chemical fever. In a prudent world, no household would be without a chemical thermometer in the medicine cabinet."

But individual tests only provide information; they don't reduce our contamination. "The truth is," Lerner says, "we are unwilling participants in a huge chemical experiment, which would never be permitted by the FDA if these chemicals came to us as drugs. But because these chemicals enter us from industrial and agricultural sources, they are not subject to testing that would ensure our safety."

The report therefore calls for "the reform of the Toxics Substance Control Act, under which chemical companies may put new compounds on the market without any studies of their effect on people or the environment."

Andrea Martin, founder and former executive director of the San Francisco's Breast Cancer Fund, strongly supports the recommendation. Martin is a breast cancer survivor who climbed Mount Fuji in 2000 with 500 breast cancer survivors and supporters. More recently, she underwent surgery to remove a brain tumor unrelated to breast cancer.

Martin, who also gave samples to the Body Burden project, was stunned by the results. "I was completely blown away," she told me. "There were 95 toxins,

59 of which were carcinogens."

Martin has never worked with or near chemicals. But she now wonders whether her formative years may have turned her into a self-described "walking toxic waste site."

When she grew up in Memphis, she and her friends loved to get splashed by the streams of insecticide sprayed by trucks that roamed the neighborhood. Later, she indulged a passion for water skiing -- in lakes clouded by chemical pollutants.

"Where did I get all these PCBs and dioxins?" she asks. "I'll probably never know."

In fact, no one is sure how industrial and synthetic chemical residues -- even long-banned pesticides such as DDT -- end up in our bodies. But scientists suspect that chemicals first pollute the air, soil, food and water, then climb through the food chain and finally accumulate in our blood, fat, mother's milk, semen and urine.

I asked Martin if she regrets getting tested. "At first, I was really angry.

But I believe knowledge is power. We're starting to learn that pollution isn't only in the air, soil and water; it's also in us."

She also wonders whether her chemical body burden has caused her cancers. "We'll never know," she says, "because right now chemical companies don't have to prove the safety of their products and no government agency has ever studied the health risks that can be caused by chemical toxins."

That may change. Last week, the Centers for Disease Control also issued its second report card on the body burden of chemicals carried by Americans. Using data from 2,500 anonymous donors, the CDC provided further evidence that chemical residues have polluted the bodies of most of us.

Although no one yet knows what amount of trace chemicals are harmful for human health, scientists and environmental health activists worry about the cumulative assault on our health.

No one wants his or her body to be another pollution site. Still, lobbyists for the chemical industry resist further regulation. "As a result," says Martin, "we're living in a toxic stew and they are, quite literally, getting away with murder."

KEY TO CONTAMINANTS

PCBs — Industrial insulators and lubricants. Banned in the U.S. in 1976. Persist for decades in the environment. Accumulate up the food chain, to man. Cause cancer and nervous system problems.

Dioxins — Pollutants, by-products of PVC production, industrial bleaching, and incineration. Cause cancer in man. Persist for decades in the environment. Very toxic to developing endocrine (hormone) system.

Furans — Pollutants, by-products of plastics production, industrial bleaching and incineration. Expected to cause cancer in man. Persist for decades in the environment. Very toxic to developing endocrine (hormone) system.

Metals — Lead, mercury, arsenic and cadmium — Cause lowered IQ, developmental delays, behavioral disorders and cancer at doses found in the environment. For lead, most exposures are from lead paint. For mercury, most exposures are from canned tuna. For arsenic, most exposures are from arsenic (CCA) treated lumber and contaminated drinking water. For cadmium, sources of exposure include pigments and bakeware.

Organochlorine insecticides. DDT, chlordane and other pesticides. Largely banned in the U.S. Persist for decades in the environment. Accumulate up the food chain, to man. Cause cancer and numerous reproductive effects.

Organophosphate insecticide metabolites — Breakdown products of chlorpyrifos, malathion and others. Potent nervous system toxicants. Most common source of exposure is residues in food. Recently banned for indoor uses.

Phthalates — Plasticizers. Cause birth defects of male reproductive organs. Found in a wide range of cosmetic and personal care products. Some phthalates recently banned in Europe.

Volatile and Semi-volatile organic chemicals. — Industrial solvents and gasoline ingredients like xylene and ethyl benzene. Toxic to nervous system, some heavily used SVOCs (benzene) cause cancer.

In a study led by Mount Sinai School of Medicine in New York, in collaboration with the Environmental Working Group and Commonweal, researchers at two major laboratories found an average of 91 industrial compounds, pollutants, and other chemicals in the blood and urine of nine volunteers, with a total of 167 chemicals found in the group. Like most of us, the people tested do not work with chemicals on the job and do not live near an industrial facility.

Scientists refer to this contamination as a person’s body burden. Of the 167 chemicals found, 76 cause cancer in humans or animals, 94 are toxic to the brain and nervous system, and 79 cause birth defects or abnormal development. The dangers of exposure to these chemicals in combination has never been studied.

These results represent the most comprehensive assessment of chemical contamination in individuals ever performed. Even so, many chemicals were not included in the analysis that are known to contaminate virtually the entire U.S. population. Two examples are Scotchgard and the related family of perfluorinated chemicals, and a group of compounds known collectively as brominated flame retardants.

A more precise picture of human contamination with industrial chemicals, pollutants and pesticides is not possible because chemical companies are not required to tell EPA how their compounds are used or monitor where their products end up in the environment. Neither does U.S. law require chemical companies to conduct basic health and safety testing of their products either before or after they are commercialized. Eighty percent of all applications to produce a new chemical are approved by the U.S. EPA with no health and safety data. Eighty percent of these are approved in three weeks.

Only the chemical companies know whether their products are dangerous and whether they are likely to contaminate people. As a first step toward a public understanding of the extent of the problem, the chemical industry must submit to the EPA and make public on the web, all information on human exposure to commercial chemicals, any and all studies relating to potential health risks, and comprehensive information on products that contain their chemicals.
