The federal government's National Toxicology Program has initiated research
that should provide a clearer picture of the effects, if any, of BPA on health,
National Toxicology Program Associate Director John R. Bucher, PhD, tells
Last fall, the National Toxicology Program issued a report examining the
potential health impact of BPA exposure from commercial products, concluding
that there was cause for "some concern" about the effects of current exposures
on the brain, behavior, and prostate gland development of fetuses, infants, and
The National Toxicology Program concluded that while the human studies were
lacking, many of the almost 1,000 animal studies showed that BPA exposure at
relatively low levels can influence certain aspects of fetal development.
But American Chemistry Council executive director of the polycarbonate/BPA
global group Steve Hentges, PhD, calls the research as a whole
"The weight of the evidence continues to indicate that trace levels of
bisphenol A are not a health risk," he says.
Hentges tells WebMD that one major problem with the newly published study,
and with all human studies, is that there is no consensus on how to best
measure BPA in the body.
BPA comes from the foods we eat, so over the course of the day levels can
vary dramatically, making it difficult to assess exposure with a single
He says the study's small sample size may have also influenced the findings.
And he points out that the behavioral differences seen in the children were
"Even if you took at face value that there is an association, it is not
clear what the clinical or medical significance would be since these children
did not meet the standard for behavior problems," he says.
