摘要
多环芳烃(PAHs)作为一类普遍存在于大气环境中的重要有毒有害有机污染物,对环境、生态和人体具有较大风险和危害,因而近年来受到研究者的广泛重视,成为环境科学领域研究热点。本文介绍了大气中PAHs的危害、来源,对常用的采样和分析方法进行了总结,归纳了我国大气中PAHs的污染现状和浓度水平以及源解析的应用,同时对我国未来的深入研究进行了展望。
Polycyclic aromatic hydrocarbons （PAHs） as akind commonly foundin theatmosphereoftheimportant toxic organic pollutants on the environment, ecology and the hu man body has greater risks and hazards, and thus received extensive attention in recent years and become environmental sci- ences research focus. This article introduces the harm, and source of PAHs in the atmosphere, the source of the sampling and analytical methods used are surmllarized, and summarizes the PAHs concentrations of atmospheric concentration levels as well as the status an d applicafon of source apportionment while the in -depth prospects ofChina＇s filture studywere carriedout.
