全氟化合物污染现状及风险评估的研究进展

Research Progress of Perfluorinated Compounds Pollution Status and Risk Assessment

全氟化合物(polyfluorinated compounds,PFCs)是近年来受到广泛关注的一类新型持久性有机污染物。PFCs因具有优良的化学稳定性、耐热性以及高表面活性,而被广泛应用于生活消费和工业生产等领域。PFCs具有难降解、生物富集和长距离迁移等特点,已在大气、土壤和水体等环境介质及生物体中检出。在生态环境中,PFCs能够通过食物链不断传递放大,其具有的多种毒性效应已对生态系统和人类造成了一定的威胁。本文主要综述了PFCs在各类环境介质的污染现状、生物的毒性效应、人类摄入健康风险评估以及PFCs的降解研究,以期为未来PFCs的研究提供参考。

As a category of emerging persistent organic pollutants,polyfluorinated compounds (PFCs) have attracted extensive attention in recent years.PFCs are widely used in the life consumption and industry due to their chemical stability,thermal stability and high surface activity.PFCs could be detected from vavious environmental media,such as atmosphere,soil and water because of their hard-degradable characteristics,bioaccumulation potential and toxicity.In the ecological environment,PFCs can be amplified through the food chain,and its toxic effects have posed a certain threat to the ecosystem and human.In this paper,we mainly reviewed the pollution status,toxicity effect,health risk assessment and the degradation technology of PFCs,which provides the theoretical basis for PFCs research in the future.
