ATMOSPHERIC CHEMISTRY AND FATE OF PERFLUORINATED COMPOUNDS AT THE AIR-WATER INTERFACE

摘要

Over the past 50 years,fluorinated alkyl substances have had numerous industrial applications.Fully fluorinated organic compounds possess unique physical and chemical properties,such as high stability due to their thermal and chemical inertness,low solubilities in polar and non-polar solvents and high densities and compressibilities compared to their hydrocarbon counterparts.Their various industrial applications include the synthesis of fluoropolymers and acting as surface protectors in carpets,leather,paper,packaging and upholstery.Recently,some perfluorinated acids have been detected in the tissues of animals,in environmental waters and in precipitation.
