Banning BPA?

The
Bisphenol-A, a man-made chemical, is used to manufacture polycarbonate products such as hard plastic baby bottles, food storage containers, water bottles, toys, pacifiers and baby teethers. The chemical also is found in epoxy resins that coat the inside of food cans and dental sealants for children’s teeth.
MU Professor of Biological Sciences Frederick vom Saal said recent studies have shown that BPA is extremely harmful in very low doses. The chemical acts like the female hormone estrogen and interferes with the body’s natural processes. BPA has been linked to adverse effects on male and female reproduction, altered immune system function, behavioural changes, learning disabilities, brain damage and an increased chance for certain cancers. Researchers are concerned about the exposure of babies to the chemical, which can cause irreversible damage.
The case for a new government safety standard concerning BPA is documented in vom Saal’s article published in the monthly journal Environmental Health Perspectives.
The last US Environmental Protection Agency risk assessment for BPA was conducted in the 1980’s. In his paper, vom Saal says that the latest research showing adverse effects of the chemical are all conducted with an amount of BPA less than the government standard at levels normally found in the human body.
“If BPA was treated as a drug, it would have been pulled immediately,” vom Saal said. “We are not saying get rid of plastics. This chemical can be replaced right now by safer materials and the public would never notice the difference.”
More than 6.4 billion pounds of BPA is manufactured every year by 15 corporations. The chemical industry conducted 11 studies and found no problems. These studies took place after vom Saal, collaborating with MU colleagues, published his findings eight years ago. Since then, independent scientists have conducted nearly 100 studies, all showing adverse health effects from low doses of BPA.
The California legislature is proposing a bill banning all use of BPA in products made for children three years of age or younger. In a hearing on the bill, vom Saal will speak to the
