An old substance requiring a new definition?

摘要

It must take a really large umbrella to provide cover for 10,000 chemicals. At least that's what some in the rubber industry think the European Chemical Agency (ECHA) is trying to do with its proposed outright ban on the per- and polyfluoroalkyl substances commonly known as PFAS. But many argue that lumping all PFAS together in proposing this blanket ban within the European Union is unfair, and will harm the industry if adopted as currently constructed.
