Every year, about four billion pounds of toxic chemicals are generated and released by U.S. industries. Do these chemicals pose a potential health threat to American families, including vulnerable groups like children and the elderly? Is their manufacture and use adequately regulated to protect both human and environmental health? Is the Chemical Safety for the 21st Century Act, signed in 2016 by former President Obama with bipartisan support, the first major overhaul of toxic chemical regulation in forty years to put human health first, or is it a fatally flawed bill that does the bidding of industry by undermining strong state environmental and public health laws? This two-volume set addresses all of those questions, and presents and examines arguments marshaled by business interests, community leaders, scientists, activists, and lawmakers alike. It provides needed information to accurately assess the impacts industrial chemicals are having in shaping the world in which we live.
