The general goal of this study was to measure the concentration of heavy metals on suspended particles and evaluate the health-risk assessment of these metals on human health. In this study, the concentration of heavy metals adsorbed on suspended particles less than 2.5 μm was determined. For determining of health-risk assessment, the developed method of USEPA was used. The health-risk assessment of carcinogen and non- carcinogen of suspended particles were evaluated in three main paths include oral ingestion, inhalation, and dermal contact. The average annual concentrations of Al, Fe, As, Cd, Cr, Cu, Mn, Ni, Pb, V, and Zn were 1.77, 1.14, 0.03, 0.02, 0.07, 0.15, 0.06, 0.03, 0.1, 0.04, and 0.14 μg/m, respectively. Between different stations, the order for the heavy metals was followed as urban>traffic>suburban. The average risk of carcinogenic at urban stations in the spring for As, Cd, and Cr was 2.2510, 2.0910, and 2.05*10, respectively.
本研究的总体目标是测量悬浮颗粒上重金属的浓度，并评估这些金属对人类健康的健康风险评估。在本研究中，测定了吸附在小于2.5μm悬浮颗粒上的重金属浓度。为了确定健康风险评估，使用了美国环境保护局（USEPA）开发的方法。通过口服摄入、吸入和皮肤接触这三种主要途径评估了悬浮颗粒致癌物和非致癌物的健康风险评估。铝（Al）、铁（Fe）、砷（As）、镉（Cd）、铬（Cr）、铜（Cu）、锰（Mn）、镍（Ni）、铅（Pb）、钒（V）和锌（Zn）的年均浓度分别为1.77、1.14、0.03、0.02、0.07、0.15、0.06、0.03、0.1、0.04和0.14μg/m。在不同站点之间，重金属的顺序为城市>交通>郊区。春季城市站点砷、镉和铬的致癌平均风险分别为2.25×10、2.09×10和2.05×10。
