Plastic Safety Comes Under Fire

摘要

Lawmakers struggled in 2008 to get a handle on the risk posed by bisphenol A (BPA), an estrogen-mimicking chemical found in polycarbonate plastics, which are commonly used to make bottles. In October, in response to a mounting body of scientific evidence, the Canadian government announced forthcoming regulations to ban the chemical from baby bottles. Several states are considering similar legislation, but as recently as September the U.S. Food and Drug Administration maintained that current exposure levels are safe.
