Per- and polyfluoroalkyl substances (PFAS) are increasingly detected in remote environments. This review aims to provide a comprehensive overview of the types concentrations PFAS found air, water, soil, sediments, ice, precipitation across different environments globally. Most recent studies on occurrence have been conducted for Arctic, Antarctica, regions China. Elevated perfluorooctane sulfonate (PFOS) Meretta Resolute Lakes reflects impact local sources like airports, while lakes located such as East Antarctica Canadian High Arctic suggest atmospheric deposition primary input. Long-chain (≥C7) accumulate short-chain remain shown Hulun Lake. Oceanic concentrated surface waters, driven by deposition, with PFOA PFOS dominating oceans due current emissions legacy contamination. Coastal areas display higher levels from sources. sediment analysis highlights ocean transport significant contributors. Antarctic coastal biological input, notably penguins. The Tibetan Plateau data confirm long-range transport, linear favoring gaseous states, branched more likely associate particulates. Climatic factors Indian monsoon temperature fluctuations affect deposition. Short-chain prevalent snowpacks, serving temporary reservoirs. Mountainous regions, Plateau, act cold traps, accumulating precursors. Future should focus identifying quantifying PFAS.
