PFAS Rainfall Contamination: Forever Chemicals Found in Pristine Rain PFAS (perfluoroalkyl substances) are synthetic compounds manufactured since 1940s industrial production. Over 500 variants exist globally, persisting indefinitely in environmental matrices with half-lives exceeding 1,000 years in soil. The Silent Spring Institute study analyzed 245 rainwater samples across six continents between January and December 2023. Concentrations ranged 12-580 ppt in pristine locations. Antarctica’s Queen Maud Land station recorded 45 ppt, definitive proof of atmospheric transport spanning 15,000 kilometers from emission sources. Industrial Sources and Environmental Transport The primary PFAS emission sources include textile manufacturing contributing 28% of global emissions, food packaging … Continue reading PFAS in Rainwater: Global Contamination Crisis Revealed by Silent Spring
