Abstract: To examine the pollution characteristic and the health risk of heavy metals in PM2.5 (particulate matter with diameter of no larger than 2.5 microns) of Xiamen, China, we analyzed 10 heavy metals (V, Cr, Mn, Co, Ni, Zn, As, Cd, Pb and Cu) in the ambient PM2.5 samples collected from urban and suburban areas in summer and winter. Result show that the concentrations of heavy metals in PM2.5 are in the order of Zn>Pb>Cu>Mn>V>As>Ni>Cr>Cd>Co. Enrichment factor analysis indicates that Zn, Pb, As, Cd and Cu are obviously influenced by anthropogenic activities. The non-carcinogenic risk of all heavy metals can be ignored, and the carcinogenic risk of most heavy metals is higher than the maximum acceptable level (10−6).
