Toxic, long-lasting contaminants detected in people living in northern Canada

Researchers have found that several long-lasting human-made contaminants have been building up in Arctic lakes, polar bears and ringed seals and other wildlife. These contaminants belong to a family of chemicals called polyfluoroalkyl and perfluoroalkyl substances (PFAS), and are used in food packaging, waterproof clothing and firefighting foams. The true number of PFAS that exist is hard to pin down, but estimates suggest there are more than 4,700 types. More:
