Per-and polyfluoroalkyl substances (PFAS) are clusters of water-soluble synthetic mixes with a significant number of utilizations, which have been generally utilized during the most recent 60 years. Perfluorooctanesulfonate (PFOS) and perfluorooctanoic corrosive (PFOA), are the most known and all around explored. With respect to numerous other natural substances that are of ecological concern, the eating regimen is the principal course of human introduction to PFAS. PFAS have been made since the 1950s, for their interesting properties such as high surface activity, thermal corrosive hindrance, and water and oil proof, PFAS have been utilized in an assortment of utilizations, for example, surfactants and surface defenders in rugs, paper industry, containers for food and upholstery and as execution synthetics in items, for example, putting out fires froths, floor shines, and shampoos etc. Far reaching application followed by natural steadiness and bioaccumulation of terminal corruption results of PFAS has brought about the worldwide event of these substances in air, oceanic just as untamed life species occupying not just areas in closeness to contamination sources, yet in addition in far off regions. The present chapters deal with manifestations and dispersal of perfluoroalkyl acids in rivers and its impact and risk assessment on environment, human and animal health.
