Polluted Bodies

Feb. 3, 2003WHEN 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/
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."
