Abstract: Some fluorinated alkyl substances are necessary in nowadays many fields because of the special properties of fluorocarbon chains.However,the traditional environmental and toxicity problems of PFOS have to be resolved.Several ways for solving the concerning problems were discussed,including the possibilities for degradation,separation and recycling use,as well as reducing the concentration in the application to be lower than the specified limit.The most reliable one is to obtain substitute for the PFOS.Several kinds of substitute were introduced and their rationality of application was also discussed.

Key words: fluorocarbon surfactant, POPs, PFOA, bioaccumulation, toxicity, sustainability, regulation
