摘要
PM_(2.5)及其携带的重金属严重危害人类健康,是全球关注的环境问题之一。研究分析山东省2017—2024年PM_(2.5)污染及不同城市PM_(2.5)中重金属的特征,以济南市为例分析富集来源,结果表明:山东省PM_(2.5)污染的高值区主要分布在鲁西北与鲁南地区;2017—2022年以聊城颗粒物污染最严重。PM_(2.5)中Al、Ca、Na、K、S、Cl元素在不同城市含量均有达1000 ng/m3以上,济南市颗粒物的重金属主要来自于燃煤、交通和工业。工业污染物的排放是该省大气污染物的主要来源,以煤炭为主的能源结构调整是控制PM_(2.5)的有效途径。
PM_(2.5) and the heavy metals it carries pose a serious threat to human health and are one of the environmental issues of global concern.This article analyzes the characteristics of PM_(2.5) pollution and heavy metals in PM_(2.5) in different cities of Shandong Province from 2017 to 2024.Taking Ji'nan City as an example,the enrichment sources are analyzed.The results show that the high-value areas of PM_(2.5) in Shandong Province are mainly distributed in the Luxibei and the Lu'nan region.From 2017 to 2022,Liaocheng experienced the most severe particulate matter pollution.The contents of Al,Ca,Na,K,S,and Cl elements in PM_(2.5) are above 1000 ng/m3 in different cities.The heavy metals in particulate matter in Ji'nan mainly come from coal combustion,transportation,and industry.The emission of industrial pollutants is the main source of air pollutants in the province,and the adjustment of energy structure dominated by coal is an effective way to control PM_(2.5).
