Scientific institutions around the world reject bans on BPA. So why are politicians imposing them?
Well-meaning laws sometimes backfire. That’s especially true when they are passed in reaction to media frenzies driven by ideology rather than science. And that’s what’s happening in the United States and Europe, where advocacy groups are raising new alarms about bisphenol A (aka BPA), a controversial plastic component used to prevent spoilage in myriad products, including containers, dental sealants, and epoxy linings.
On Tuesday, the California State Senate approved a ban on baby bottles and sippy cups that contain BPA, with the measure now going to the Assembly for a final vote. Set to take effect next July, the ban was approved despite the fact that no governmental science-based advisory board in the world has concluded that BPA is harmful.
But political systems often operate with limited information and short time horizons, while much of science is complex and evolving. Bowing to relentless campaigns, restrictions on BPA used in baby bottles have been imposed politically in 11 states and in a few countries, such as France and Canada.
In a sidestep around the science, activists are aggressively turning up the heat on legislators around the world. The latest uproar involves the presence of miniscule amounts of BPA on thermal paper receipts printed at supermarkets or ATMs, and on the money that comes in contact with them. The brouhaha has touched off a swirl of recent media coverage, much of it just plain wrong. (The American)
