Bisphenol A Tied to Health Problems
Study Shows Plastic Chemical Linked to Heart Disease, Diabetes; Industry Says No Proof Bisphenol A Is to Blame

"The FDA says there has to be a reasonable certainty of safety in order
to use these products. I look at the entire literature and I say there is a
very reasonable certainty of harm," says vom Saal.
An FDA spokesperson wasn't immediately available to comment on that. The FDA
recently issued a draft
report on the safety of bisphenol A in food contact items (food and drink
packaging). That draft report deemed bisphenol A food and drink containers safe
for typical use. European regulators recently took a similar stance.
But another government agency, the National Toxicology Program, doesn't rule
out all risk from bisphenol A. In a separate
report the NTP notes "some concern" for effects on the brain, prostate gland, and on behavior in fetuses, infants,
WebMD contacted the American Chemistry Council (a trade group for the
plastics industry) and the North American Metal Packaging Alliance (a trade
group for the canned goods industry) for their comments on the study.
The American Chemistry Council
replied by email with a statement underscoring the limitations mentioned in the
study. Because of those limitations, "this new study cannot support a
conclusion that bisphenol A causes any disease," Steven G.
Hentges, PhD, of the American Chemistry Council's Polycarbonate/BPA Global
Group, states in a news release. "The weight of scientific evidence
continues to support the conclusion of governments worldwide that bisphenol
A is not a significant health concern at the trace levels present in some
consumer products," Hentges states.
The council doesn't totally
dismiss the study, but it sees the study as being "primarily useful for
generating hypotheses that can be tested with more appropriate experiments or
analyses," states the council's news release.
The North American Metal Packaging
Alliance (NAMPA) also emailed a statement, which points out that study
participants only provided one urine sample, and that the body "quickly and
efficiently" eliminates bisphenol A through urine. "To suggest that BPA
concentrations measured at a single point in time during the process of
elimination from the body correlate in any way directly with serious chronic
disorders is entirely unsupported and an unsubstantiated scientific leap,"
states NAMPA, adding that "while the study raises interesting questions, it
provides no scientifically defensible answers" and requires further
