The fact that oceans, rivers and other bodies have been terribly polluted by human activities is old news. But new research suggests that even rainwater across the world could be polluted by “per- and polyfluoroalkyl substances,” (PFAs) leaving them unfit for human consumption.
PFAs are hazardous man-made chemicals that spread globally in the atmosphere. They are used to make fluoropolymer coatings that can resist heat, oil, stains, grease and water.
