Unsafe at any Dose? Diagnosing Chemical Safety Failures, from DDT to BPA

By:

Piecemeal, and at long last, chemical manufacturers have begun removing the endocrine-disrupting plastic bisphenol-A (BPA) from products they sell. Sunoco no longer sells BPA for products that might be used by children under three. France has a national ban on BPA food packaging. The EU has banned BPA from baby bottles. These bans and associated product withdrawals are the result of epic scientific research and some intensive environmental campaigning. But in truth these restrictions are not victories for human health. Nor are they even losses for the chemical industry.

For one thing, the chemical industry now profits from selling premium-priced BPA-free products. These are usually made with the chemical substitute BPS, which current research suggests is even more of a health hazard than BPA. But since BPS is far less studied, it will likely take many years to build a sufficient case for a new ban.
