大气颗粒物及其组成研究进展(下)

Research progress of atmospheric particulates and its composition(Ⅱ)

颗粒物是空气中最重要的污染物之一,由于颗粒物表面的吸附作用,其组分非常复杂,其中含有多种有毒有害的化学成分,对大气环境造成不良影响,并危及人体健康。借助大气颗粒物及其组成成分的测定,通过污染源解析分析其来源及影响因素,控制大气颗粒物的排放,对于保证大气环境质量、改善人们的生存环境具有重大意义。本文对此进行综述,着重介绍大气颗粒物及其组成成分、源解析及测量技术的最新进展。

Particles is one of the most important pollutants in the air.Because of its adsorption of surface particles contain a variety of poisonous and harmful chemical composition,which makes great impact on atmospheric environment and endanger human body health.With the help of measuring atmospheric particles and its composition and analyzing the resource and influence factors through resolving pollution source,the control of atmospheric particulates emissions is of great significance to guarantee the quality of atmospheric environment and improve the people＇s living environment.Above all was overviewed in this paper which emphases is the development of atmospheric particulates and its components,analysis of pollution source and measuring technology.
