Plastic Chemical Safety Weighed
Expert Panel Notes No Major Health Concerns About Plastic Chemical Bisphenol A
WebMD News Archive
Aug. 8, 2007 -- An expert panel today noted no major health risks in their
review of data on a plastic chemical called bisphenol A.
Bisphenol A, or BPA, is found in polycarbonate plastic, which is used in
various products including food and drink containers, as well as resins that
line metal food cans.
The expert panel was convened by the Center for the Evaluation of Risks to
Human Reproduction (CERHR) of the National Toxicology Program.
The 12-member panel included doctors and researchers from universities, the
federal government, the American Cancer Society, and the drug companies Pfizer
Their task was to review reams of research on bisphenol A's safety, based on
lab tests on animals and studies of human exposure to bisphenol A.
The panel notes "some" concern that exposure to bisphenol A causes
neural and behavioral effects in fetuses, infants, and children.
The panel notes "minimal" concern that exposure to bisphenol A in
fetuses, infants, or children, may lead to early puberty and that fetal
exposure to bisphenol A may affect the prostate.
The panel notes "negligible" concerns that fetal exposure to
bisphenol A produces birth defects and malformations, and "adverse
reproductive effects" in adults exposed to bisphenol A. The panel's report
doesn't define "adverse reproductive effects."
The CERHR will solicit public comments on its report.
Reaction to Panel's Work
The panel's conclusions are "very reassuring," Steven Hentges,
PhD, tells WebMD. Hentges is the executive director of the
polycarbonate-bisphenol A global group of the American Chemistry Council, an
industry organization that represents firms including companies that make
The nonprofit Environmental Working Group issued a statement criticizing the
panel's conclusions, claiming that the panel endorsed "an error-riddled,
industry-influenced 'report' minimizing the risks that BPA poses to
The panel's work comes in the wake of a statement written by 38 scientists
who voice concern about bisphenol A's safety. That statement appears online in
the journal Reproductive Toxicology.
About Bisphenol A
Data from lab tests and research on animals indicate that bisphenol A
"may mimic the natural female sex hormone, estradiol," according to
CERHR background information.
