[求助] PAHs

PAHs are aromatic hydrocarbons with two or more fused benzene rings with natural as well as
anthropogenic sources. They are widely distributed environmental contaminants that have detrimen-
tal biological effects, toxicity, mutagenecity and carcinogenicity. Due to their ubiquitous occurrence,
recalcitrance, bioaccumulation potential and carcinogenic activity, the PAHs have gathered significant
environmental concern. Although PAH may undergo adsorption, volatilization, photolysis, and chemical
degradation, microbial degradation is the major degradation process. PAH degradation depends on the
environmental conditions, number and type of themicroorganisms, nature and chemical structure of the
chemical compound being degraded.

多环芳烃是与两个或更多个稠合苯环的天然以及人为来源的芳烃。它们分布广泛,有不利的生物效应,毒性,诱变性和致癌性环境污染物。由于它们无处不在发生,顽抗,生物累积潜力和致癌活性,所含的PAHs聚集显著的环境问题。虽然多环芳烃可能发生吸附,挥发,光解,降解和化学降解,微生物降解是主要的降解过程。 PAH的降解依赖于环境条件,数量和微生物,性质和被降解的化学化合物的化学结构式。
