Contamination levels of per- and polyfluoroalkyl substances (PFAS) in recent North American precipitation events. A review.

Per- and polyfluoroalkyl substances (PFAS), known as forever chemicals, have received international attention over the last two decades for their health risks and environmental persistence. One pathway of human exposure to PFAS is by rainwater. This review aims to analyze current studies of legacy and emerging PFAS contamination levels in rainwater in North America.
