Metal Components and Health Risk Assessment of Coarse Particulate Matter

Abstract

In order to study the concentrations and health risk of heavy metals in different particulate matter in JingYue in ChangChun City, TSP samples were collected in different seasons from April to June in 2017. The results showed that the concentrations of particulate matter exceeded the standard. The concentrations of metals were Cd<Co<Cr<Cu<Ni<V<Mn<Pb<Zn<Mg<Sn<Al<Fe<Sb, Pb and Cd exceeded the standard. Through correlation and principal component analyses showed that the 14 metals mainly came from the coal sources, the dust sources and the second transmission industry sources. Enrichment factors showed that except for Mn, other metals had different degrees of enrichment phenomenon. The HQ values of 6 metals Mn, Ni, V, Cr, Cd and Sb were less than 1 which didn’t exist noncarcinogenic risk. The R values of Pb, Cr, Cd and Ni were less than 10-6, suggested the non-existence of carcinogenicity.
