polyfluoroalkyl

A new study by researchers at Harvard University shows that the water supplies of nearly 6 million Americans are tainted with unsafe levels of polyfluoroalkyl and perfluoroalkyl substances, or PFASs – a class of industrial chemicals linked to potentially serious health problems. [1]
PFASs have been used for decades in a wide variety of industrial and commercial products, including non-stick coatings on pans, food wrappers, water-repellent clothing, and firefighting foam.

Perfluoroalkyl substances (PFASs) have been used in a variety of products for many decades. It is well worth repeating that one of the more dangerous variants of PFASs that was formerly found in Teflon until it was replaced by a similar substance which may also be toxic. But that’s not the only place it’s found.
