Endocrine disruptors, synthetic chemicals that mimic and interfere with
natural hormones, lurk everywhere from canned foods and microwave popcorn
bags to cosmetics and carpet-cleaning solutions. The chemicals, which
include pesticides, fire retardants and plastics, are in thermal store
receipts, antibacterial detergents and toothpaste (like Colgate's Total
with triclosan) and the plastic BPA which Washington state banned in
baby bottles. Endocrine disruptors are linked to breast cancer, infertility,
low sperm counts, genital deformities, early puberty and diabetes in
humans and alarming mutations in wildlife. They are also suspected in
the epidemic of behavior and learning problems in children which has
coincided, many say, with wide endocrine disruptor use.
Like Big Pharma, Big Chem holds tremendous sway at the FDA, which gave the endocrine disruptor BPA a pass in March, citing "serious questions"about the applicability of damning animal studies to humans. But in April, research from the Proceedings of the National Academy of Sciences
presented new evidence of the ability of endocrine disruptors--in this
case the pesticide, chlorpyrifos--to harm developing fetuses. Janette
Sherman, a pesticide expert and toxicologist, has studied the effects of
chlorpyrifos (found in Dow's pesticide Dursban) for many years and
spoke with AlterNet about what her research has revealed.
Martha Rosenberg: Published studies, including your own, signaled safety problems with Dursban years ago. The EPA's own data found eight out of 10 adults and nine of 10 children had "measurable concentrations." Dow paid a $2 million penalty for hiding Dursban's risks from 1995 and 2003 in New York. But the pesticide was not banned for residential use until 2000, and after it was banned, people were allowed to use remaining quantities. Why did the cases that you and others uncovered seem to have little effect?
Janette Sherman: Dow attorneys took my deposition for four eight-hour
days in the mid-1990s and I supplied over 10,000 pages of medical
records, depositions, EPA documents, patent information and toxicology
studies on which I based my opinion. Even though genetic analyses were
conducted for the paper and genetic causes for the defects were ruled
out--siblings who were not exposed to chlorpyrifos, for example, were
normal--Dow termed the cases genetic and was able to stop most, if not
all, chlorpyrifos birth-defect suits.
Dow has almost unlimited money and personnel to fight families and
small-town attorneys and they send multiple personnel to the EPA to
argue their side. There is also no penalty for withholding information.
MR: Dow claimed there was insufficient proof of chlorpyrifos exposure.
JS: Yes and one of the ironies, that I have cited in several papers, is
that monitoring data for pesticide levels, either at the time of
application or at the time of birth, is simply not done. People have no
records and no way of collecting records of pesticides they have been
exposed to.
MR: Lorsban, the agricultural version of Dursban, is still widely in use in crops like apples, corn, soybeans, wheat, nuts, grapes, citrus and other fruit and vegetables. Virginia Rauh, the author of the recent Proceedings of the National Academy of Sciences paper cautioned pregnant women to seek organic produce to avoid chlorpyrifos.
JS: I believe farm workers and pregnant women are at risk and
obviously, a pesticide that is used widely in crops will also get in the
drinking water. I don't know how widespread chlorpyrifos use is
overseas and in poor countries but the same risks apply.
MR: You published a paper in the European Journal of Oncology in 1999 which is eerily predictive of recent Proceedings of the National Academy of Sciences research
about children exposed in the womb to the pesticide chlorpyrifos. This
research found actual structural changes in exposed children's brains,
especially related to emotion, attention and behavior control.
JS: Dursban (chlorpyrifos) is a pesticide manufactured by Dow Chemical
Co. and Eli Lilly that has both organophosphate and tri-chlorinated
pesticide characteristics and toxicities. Working as a legal consultant,
I evaluated eight children with profound abnormalities whose families
had proof of their child’s exposure to chlorpyrifos in the womb. I was
stunned by how much the children resembled one another--they looked so
similar they could have been siblings or cousins. The children were all
severely retarded and needed feeding and diapering. One had quadriplegia
and another died soon after I examined him.
MR: In your 1999 paper you refer to the brain problems cited in the Proceedings research as possibly pesticide-related.
JS: Yes. The children also had corpus callosum defects, which means
there was no connection between their right and left side of their
brains.
MR: Where were the children located and where did you examine them?
JS: The children were in Arkansas, on Long Island and in California.
The use of Dursban occurred in the homes. Since Dursban has been
restricted from home use [in 2000] of concern are agricultural use of
chlorpyrifos that continues and questions of birth defects in women
agricultural workers. I examined some of the children in their homes. In
other cases, the parents brought them to be examined, if they had vans
equipped to move the children.
MR: In addition to the mental retardation, paralysis and
structural brain problems you found deafness, cleft palate, eye cysts
and low vision, nose, brain, heart, tooth and feet abnormalities and
many sexual deformities.
JS: Yes, the sexual and reproductive defects included undescended
testes, microphallus [tiny penis], fused labias [vaginal lips] and
widespread nipples. I also report in the paper, 13 adverse reproductive
cases linked to chlorpyrifos from Dow's own research database (European Journal of Oncology, Vol. 4, n.6, pp 653-659 1999).
MR: Anyone who is aware of the effects of endocrine-disrupting
pesticides on wildlife can't help but think of the frogs reported with
no penises in so many U.S. streams or the sexual abnormalities reported
in both male and female birds and other animals.
JS: Yes, the children's defects mirrored effects of endocrine
disrupters seen in wildlife. They also mirrored Dow's own rat studies
which showed testicular and urogenital deformities, skull and sternebrae
(part of breast bone) abnormalities and cleft palate in exposed
animals, especially from in utero exposure to chlorpyrifos (European Journal of Oncology, Vol. 4, n.6, pp 653-659 1999).
MR: You have not been one to shirk from doing battle with Dow
and other giant chemical companies. You write in one paper, "Dow has
been reluctant to accept that exposure to a chlorinated organophosphate
chemical designed to kill insects by interfering with neurological
function could harm the developing human." That's pretty direct.
JS: Dow works powerfully against criticism. During one legal
proceeding, I overheard a Dow attorney say, "This is the last deposition
Sherman will appear at." It takes nerve to go up against them.
MR: Before medical school you worked for the Atomic Energy
Commission and at the U. S. Navy Radiological Laboratory. But now you
publish outspoken books and papers about radiation poisoning related to
Chernobyl, Fukushima and other sources. What shaped your medical career?
JS: In the 1970s, I began doing worker compensation cases involving
people working in foundries and I began to see a high incidence of lung
disease. When the occupational medicine department at my university told
me the information was anecdotal and there were not enough cases to be
statistically significant, I sent the information to former Senator Phil
Hart, D-Mich, who was working with the consumer advocate Ralph Nader at
the time. Soon, the information I had uncovered was on the front page
of the New York Times and I began to be flooded with
information and requests from people who had knowledge of other apparent
environment toxicity cases. I became specialized in toxicology and
continue to cover environmental hazards presented by radiation,
chemicals and pesticides like Dursban.
MR: Since Dursban's ban, there have been calls for a Lorsban ban because of its effects on farmworkers. In India,
Dow's offices were raided by Indian authorities for allegedly bribing
officials to allow chlorpyrifos to be sold in the country. (Dow bought
the Union Carbide plant in India where the 1984 Bhopal gas leak
occurred.) And In 2008, the National Marine Fisheries Service sought
chlorpyrifos restrictions because of dangerous levels seen in Pacific
salmon and steelhead. Yet, like DDT, there have been calls to bring
Dursban back into wider use--especially when bedbug infestations hit
major cities.
JS: Well, with many of these harmful chemicals, you need to follow the
money. In some cases, companies making harmful chemicals are even making
drugs to treat their effects, like anti-cancer drugs. But consumers are
not off the hook either, because we fail to ask questions, pay
attention and read the fine print.
