It’s raining PFAS: rainwater is unsafe to drink even in Antarctica and Tibet
Per- and polyfluoroalkyl substances (PFAS) are man-made hazardous chemicals that are spread globally in the atmosphere and as a result they can be found in the rainwater and snow in even the most remote locations on Earth. During the last 20 years, guideline values for PFAS in drinking water, surface waters and soils…
