Pollution Characteristic Analysis and Potential Ecological Risk Assessment of Heavy Metal in PM2.5 in Shuozhou in 2022
Objective To study the pollution characteristics of heavy metal in the atmosphere and evaluate its im-pact on human health,so as to provide a supporting basis for taking targeted measures.Method A PM2.5 automatic monitoring super station was used to monitor 21 heavy metal elements in PM2.5 in Shuozhou from January 1 to De-cember 31 in 2022,and by the enrichment factor method and potential ecological risk assessment method,the pol-lution characteristics,enrichment degree and potential risk status of atmospheric heavy metal were analyzed.Result The EF value of Zn,Pb,Sb,Sn,Se and Cd was all greater than 100,with high enrichment or even super enrich-ment levels,indicating that these elements were greatly influenced by human factors.The potential ecological risk of heavy metal in PM2.5 in Shuozhou was as follows:Cd>Se>Pb>Cu>Ni>Zn>V>Cr>Mn>Ti,Cd and Se exhib-ited high ecological risk potential,and the Cd element had the highest ecological risk.
