大气可吸入颗粒物中有机污染物的研究进展

有机污染物是可吸入颗粒物的重要组成部分,随着工业的发展、城市化进程的加快,颗粒有机物的污染日益突出,成为人们普遍关注的焦点。开展有毒有害有机物及不同污染源有机示踪化合物的系统研究,对城市大气污染的治理具有重要的意义。本文概述了环境空气中有机污染物的化学组成、分类;对燃烧源、餐饮源、交通源等几种污染源的排放特征进行了着重分析,表明污染源不同,其排放特征具有很大差异。同时阐述了对有机污染物进行源解析的主要方法,并进一步探讨了有机污染物的预处理方法和分析检测技术。

STUDY PROGRESS ON ORGANIC POLLUTANTS IN INHALABLE PARTICLES IN ATMOSPHERE

With the fast development of industry and urbanization process,organic pollutants,the main composition of inhalable particles,are of special interest since organic pollution in atmosphere become more and more severe.The systemic research of toxic organic compounds and organic molecular tracers are significantly important for treatment and control of urban air pollution.This paper briefly presented the chemical composition and classification of organic pollutants in inhalable particles.The emission characteristics which attracted much attention of main pollutant sources from combustion,cooking,motor vehicle were analyzed respectively in this paper,indicating that different pollutant sources lead to different emission characteristics.At the same time,the primary source analysis of organic pollutants was described.Furthermore,the pretreatment and analysis technique for organic pollutants were also discussed.
