摘要
结合当前大气颗粒物附着重金属、类金属元素方面的污染影响研究,主要集中在PM10与PM2.5中,在环境保护工作要求增高的背景下,缺乏更精细分级粒径颗粒物的负载重金属成分与风险研究。本文先阐述了不同分级粒径颗粒物的采集分析方案,然后讨论大气颗粒物有害元素的分布富集情况,最后分析大气颗粒物有害元素的风险特征,更好地维护空气环境质量。
Based on the current research on the pollution impact of heavy metals and metal like elements attached to atmospheric particulate matter,it is mainly focused on PM10 and PM2.5.In the context of increasing environmental protection requirements,there is a lack of research on the loading heavy metal components and risks of more finely graded particle size particulate matter.This article first elaborates on the collection and analysis plans for particles with different grading sizes,then discusses the distribution and enrichment of harmful elements in atmospheric particles,and finally analyzes the risk characteristics of harmful elements in atmospheric particles to better maintain air environmental quality.
