综述了东亚地区大气颗粒物中多环芳烃及其衍生物（包括硝基多环芳烃和氢化多环芳烃）的分布特征。通常，具有两个或三个芳环的PAH化合物主要释放到气相中，而那些含有三个或更多芳环的PAH化合物与颗粒物（PM）排放有关。颗粒物中的多环芳烃主要吸附在细颗粒物上，而与粗颗粒物的吸附量很小。调查不同地区多环芳烃的浓度水平，不仅可以反映污染物的现状和来源，还可以指导制定控制策略。研究结果表明，中国的多环芳烃污染比日本、韩国等东亚国家严重。
A review is presented on the distribution and characterization of polycyclic aromatic hydrocarbons (PAHs) and their derivatives, including nitro-PAHs and hydro-PAHs, on atmospheric particulates of East Asia. Generally, PAH compounds with two or three aromatic rings are released mainly into the gas phase, while those containing three or more aromatic rings are associated with particulate matter (PM) emission. Particle-associated PAHs are primarily adsorbed on fine particles, and little associated with coarse particles. Investigation into the concentration level of PAHs in different areas can serve not only to reflect the pollutant status and sources but also to lead to the formulation of control strategies. The results of the present study show that China has more severe PAH pollution than such East Asian countries as Japan and Korea.
