Regulations of PFAS and Future Perspectives

Abstract

National and international chemicals schemes employ often different selection and/or categorization of PFAS. Some employed grouping-type definitions based on the characteristic chemical structure, but others specified each chemical as the list of target chemicals of PFAS. Different management options are applied to specific or group of PFAS chemicals in each definition of PFAS. Although the list of target chemicals are sometimes largely different each other, however, the author thinks that starting definition of PFAS is somewhat common in all national/international schemes but different management considerations for variety of uncertainties and/or lack of information in PFAS chemicals result in different appearances among national and international schemes. Management actions corresponding to the uncertainties/lacking of the scientific information need to be established, probably by the appropriate combination of precautionary approach and risk assessment schemes depending on the different nature of information and management concern.
