| 摘 要： | 全氟化合物(perfluorinated compounds,PFCs)是碳氢类化合物及其衍生物中氢原子全部被氟原子取代后形成的一类化合物。全氟辛烷磺酸(perfluorooctane sulfonate,PFOS)是一种典型的全氟化合物,对于生物具有多方面的毒性。研究发现,PFOS广泛存在于环境中,造成了一定的污染,PFOS的降解成为亟待解决的问题。但是由于PFOS稳定性高,降解较为困难,尤其是在生物降解方面的研究较少。本文主要介绍了PFOS降解技术的发展现状以及存在的问题,并提出PFOS生物降解的可能途径。

| Abstract: | Perfluorinated compounds (PFCs) is a class of hydrocarbons (and derivatives) in which hydrogens are replaced by fluorine atoms. Perfluorooctane sulfonate (PFOS) is a representative PFCs. It has many aspects of toxicity for living organisms. Research shows that PFOS almost exists everywhere and makes pollution, and the degradation of PFOS becomes an urgent problem. However, PFOS has high stability to be degraded. In particular, studies of successful PFOS biodegradation are limited. Here, we introduce the developing status and highlight challenges of PFOS degradation. In addition, we suggest potential pathways for PFOS biodegradation. |
