摘要
近年来,水成膜泡沫灭火剂(AFFF)已被确定为环境中全氟烷基和多氟烷基物质(PFAS)的重要来源。6∶2氟调聚磺酰胺烷基甜菜碱(6∶2FTAB)是AFFF的一种常见成分,而6∶2氟调聚磺酸(6∶2FTSA)是6∶2FTAB和其他前体的潜在降解中间体。6∶2FTAB和6∶2FTSA都是全氟己基乙基磺酰衍生物(n-C_(6)F_(13)CH_(2)CH_(2)SO_(2)—)。这两种化合物经常在AFFF释放点附近被检测到,它们会对周边的陆地和水生生态系统产生负担。对6∶2FTAB和6∶2FTSA在光环境、水生生物环境、微生物环境和植物环境中的降解状况进行了综述,使人们对这类物质在环境中的降解模式能够有一个初步的认识。
In recent years,aqueous film-forming foam extinguishers(AFFF) have been identified as important sources of perfluoroalkyl and polyfluoroalkyl substances(PFAS) in the environment.A common component of AFFF is the 6:2 fluorotelomer sulfonamidoalkyl betaine(6:2 FTAB),while 6:2 fluorotelomer sulfonic acid(6:2 FTSA) is a potentially degraded intermediate of 6:2 FTAB and other precursors.Both compounds are PFASs most commonly detected in AFFF-affected sites,contaminating nearby terrestrial and aquatic ecosystems.In this paper,the degradation of 6:2 FTAB and 6:2 FTSA in light-irradiating,aquatic,microbial and botanic environment are reviewed.Hopefully,people can have a primary comprehension of the degradation mode of these substances in the environment by reading this artical.
