-- A new review suggests that adult exposure to bisphenol A, a common
plastic ingredient may affect the brain, reproductive system and
immune system in men and probably also in women.
The study was supported by the National
Institute of Environmental Health Sciences and others and published
in the Aug-Sept 2008 issue of Reproductive Toxicology.
The reviewers went through 199 studies
on the effect of low doses of BPA below 50 mg/kg/day in model
animals and found many effects of BPA are similar to that of
estrogens diethylstilbestrol and ethinylestradiol.
The potency of the effects is about 10
to 1000 times less than that of diethylstilbestrol or
ethinylestradiol.
The researchers said "
particular
outcomes occur in response to low dose BPA exposure." and "
We
are confident that adult exposure to BPA affects the male
reproductive tract, and that long lasting, organizational effects in
response to developmental exposure to BPA occur in the brain, the
male reproductive system, and metabolic processes."
They also believed that it is likely,
but needs to be confirmed, that "
adult exposure to BPA affects
the brain, the female reproductive system and the immune system and
that developmental effects occur in the female reproductive system."
The National Health and Environmental
Effects Research Laboratory and U.S. Environmental Protection Agency
has reviewed the report and approved publication of the report.
Bisphenol A is commonly present in
polycarbonated plastics, which are commonly used in food and beverage
containers and epoxy resins.
