In 1976, the Toxic Substances Control Act, which sought to regulate the safety of many chemicals in use, was signed into law. Now, Congress appears ready to give it a complete overhaul. The reason for the unusual display of bi-partisanship is a growing acknowledgement from a variety of interest groups that the law does not give the federal government enough authority to examine the safety of chemicals in use or to keep unsafe ones from coming on the market. After years of efforts to reform the law, this week the House passed a bill by big margins. The Senate is expected to follow. Guest host Sabri Ben-Achour and a panel of experts discuss overseeing the safety of chemicals.
