She guides us through what PFAS are, why they're a problem, and what can be done about them. Short for "per-and polyfluoroalkyl substances," PFAS are a class of thousands of man-made chemicals that have been around since the 1940s. Scientists are still learning about the effects of PFAS on humans, but studies show these chemicals can harm different systems in the body. Blum says that government regulation would force companies to take action, but the responsibility also falls on the private sector to stop using PFAS in their products. She says it's really up to the manufacturers and the government to stop – or ban – using these chemicals.
