Discussion on Sources and Pollution Control Measures of Perfluorooctanoic Acid (Salt) in the Environment

Abstract

水污染及处理 Abstract Perfluorooctanoic Acid (salt) (PFOA) is widely applied in fluoropolymeric synthesis and fabric finishing fields and is the most characteristic pollutant present in environmental mediums. In this paper, based on the introduction of the control requirements of PFOA at home and abroad, the main sources and transport pathways of PFOA in the environment are analyzed. Furthermore, the countermeasures and suggestions are proposed in terms of the establishment of environmental criteria system, the development and application of substitutes of PFOA, and pollution control and remediation techniques in order to control the pollution of PFOA in the environment.
