含氟有机化合物的生态迁移及转化

含氟有机化合物的众多特性使得其在各方面得到越来越广泛的应用，同时也成为了一种较普遍的环境污染物。本文列举了含氟有机化合物的应用类型及相应的应用特点；指明其污染途径和毒性特征；从含氟有机物的分子结构特征、降解茵的类型、外部因素三方面阐明了其生物降解特性；总结了酶作用于碳氟键使得含氟有机物发生降解的四种作用；并介绍了含氟有机污染物的生物处理和生态修复的一般方法。

Biological Transformation of Organofluorine Compounds

The use of organofluorine compounds has increased throughout this century, and they are now ubiquitous environmental contaminants. Although generally viewed as recalcitrant because of their lack of chemical reactivity, many fluorinated organics are biologically active. Several questions surrounding their properies of biodegradation, mechanisms of deflourination, biotreatment and bioremediation are reviewed.
