【摘要】 多环芳烃是一类具有"三致"效应(致癌、致畸、致突变)的持久性有机污染物。环境中的多环芳烃主要来源于碳氢化合物的不完全燃烧,并且广泛存在于各种介质中。水是生命之源,在人类的生产生活中有着不可替代的作用,然而世界大部分地区的表层水都不同程度地受到多环芳烃的污染。本文就多环芳烃的性质、来源、在水中的分布状态、危害、处理方法等进行了回顾和综述,并展望了我国多环芳烃研究的发展方向。更多还原

【Abstract】 Polycyclic aromatic hydrocarbons(PAHs) are persistent organic pollutants,known for their teratogenic,carcinogenetic and mutagenic effect.They are derived from incomplete combustion of pyrolysis of organic materials containing carbon and hydrogen and exist in the environment ubiquitously.Water is the source of life and indispensable in our life.Research results show that in large areas of the world,the surface water is polluted by PAHs in varying degrees.The paper introduces the sources,quality,harm,distribution,and disposal method of Polycyclic Aromatic Hydrocarbons in the water,and puts forward prospects of the development of PAHs research in our country.更多还原
