ABSTRACT
In 2020, the mass concentration of PM2.5 in Shijiazhuang urban area was(80.30±71.43)μg/m3. The Spearman correlation analysis between metals and metalloids showed that Sb with Cd, Pb, Ni, Se, Cd with Pb, Ni, Se, Pb with Ni, Se, Ni with Se, and Se with Tl were positively correlated, with a coefficient greater than 0.5. The main sources of metals and metalloids of PM2.5 were traffic emissions, fuel combustion, metal smelting and dust. The HQ values of Pb, Hg and Mn for each population were less than 1, with lower non-carcinogenic risk. The R values of carcinogenic risk of Ni and Cd in each population were less than 1×10-6, which could be acceptable risk level for the population. The R values of carcinogenic risk of As and Cr in different populations were between 1×10-6 and 1×10-4, with potential carcinogenic risk, particularly higher in adult males.
