细颗粒物PM2.5的污染特征及环评工作的应对研究

Research on the characteristics of PM2.5 and the analyses about it in the environment impact assessment

综述了国内外对细颗粒物PM2.5的研究进展,梳理了其来源、化学组成、在颗粒物中所占比重及对环境和人群的影响效应,并且针对其污染特征,对环境影响评价中PM2.5的相关工作现状进行了分析,对今后工作的发展提出了建议。

Research progress of fine particle PM2.5 at home and abroad was reviewed,including its sources,chemical composition and its proportion in TSP and PM10,as well as the influences on the environment and human body,in the perspective of the environment impact assessment.Researches on its implementation in environment impact assessment were done also,as well as the advice on its future development,based on their characteristics.
