摘　　要：多环芳烃(PAHs)在环境中大量存在,由于其具有致癌性和致突变性而受到国内外学者的广泛关注。介绍了多环芳烃(PAHs)的来源以及在环境中的分布,综述了其在大气、水体、土壤和植被中的迁移转化规律,重点概括了环境中多环芳烃(PAHs)的几种降解方法,包括微生物降解、生物修复及其它物理化学方法,并简单提出了目前针对环境中的多环芳烃(PAHs)污染国内外采取的降解技术以及相应的控制措施。Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants which exist in the environment,and have attracted popular attention due to their carcinogenic or mutagenic nature. The sources and the distribution of PAHs in the environment are introduced. Furthermore, it explains the patterns of migration, the transformation of PAHs in the air , water, soil and vegetation , and in particular generalizes the decomposition of PAHs in the environment, including microbe degradation, the biologic treatment for remediation and some physical chemical removal methods. It reviews some decomposable technology especially applied to treat PAHs pollutants and its controlling methods.
