| 摘 要： | 多环芳烃(PAHs)是一类广泛分布于海洋环境中的含有两个以上苯环的有机化学污染物.苯并a]芘(BaP)是一种由5个苯环组成的分布广泛、致癌性极强的多环芳烃化合物,人们将其作为多环芳烃的指示物,通过研究其在环境中的产生、迁移、转化、降解及毒理作用来判断多环芳烃的污染情况.BaP已成为国内外环境监测的重要指标之一.本文综述了不同环境中BaP的来源与分布,BaP在环境中的行为,微生物对BaP的代谢途径,以及微生物降解BaP的相关限制因子,并结合作者在这方面研究的部分工作与目前国际研究的热点,提出值得进一步探究的有关问题.图4表3参51

| Abstract: | Polycyclic aromatic hydrocarbons (PAHs), a kind of organic chemical pollutants consisting of two or more fused benzene rings, are widely distributed in environment. PAHs, particularly the types with higher molecular weight, cause great environmental concern because of their mutagenic, teratogenic and carcinogenic properties. Benzo(a)pyrene (BaP) is a five-ring polycyclic aromatic compound with acute carcinogenicity. It is classified as a priority pollutant in environment assessment. This paper reviews the occurrence and distribution of BaP in environment, as well as the ability and pathway for BaP degradation by microorganisms. In addition, approaches for improving microbial degradation of BaP are discussed. Fig 4, Tab 3, Ref 51 |
