Abstract: Perfluorooctane sulphonate (PFOS) is a new type of persistent organic contaminants caused by human living and detected throughout the world. PFOS enters into the environment through fluorine- containing wastewater treatment plant discharges, industrial production of PFOS or its precursors, atmospheric deposition, etc. It is mainly distributed in water and sediments. The PFOS contamination occurs mainly in densely populated and industrialized regions, and areas surrounded water treatment plants. The adsorption of PFOS is affected by pH, cation or anion surfactants, and concentration of salts. This paper analyzes recent domestic and international literature and studies PFOS to give a summary of PFOS pollution characteristics in water and sediment environments.

Key words: pollution characteristics, sediment, water, perfluorooctane sulphonate (PFOS)
