越来越多的证据表明，细粉尘颗粒（PM2.5）的毒性与特定成分有关，而不是其质量。然而，对PM2.5的化学成分和健康风险的研究还不够。本研究分析了PM2. 5中的金属、多环芳烃（PAHs）、有机氯农药（OCPs）和多氯联苯（PCBs），并评估了户外活动对健康的风险。重金属的含量比多环芳烃高一个数量级，有机氯农药和多氯联苯的含量和检出频率远低于重金属和多环芳烃。PM2.5中致癌物的终身超额致癌风险（LECR）超过最小风险（1 x 10（-6）），为1.33-3.44 x 10（-6）（第5 - 95百分位数），因为Cr（VI），As和Cd显示出较高的贡献。2岁以下儿童
Increasing evidence suggests that the toxicity of fine dust particles (PM2.5) is linked to specific components rather than their mass. However, research on the chemical composition and health risk of PM2.5 is insufficient. This study analyzed the metals, polycyclic aromatic hydrocarbon (PAHs), organochlorine pesticides (OCPs), and polychlorinated biphenyls (PCBs) present in PM2.5 and evaluated their risk to health during outdoor activities. The concentration of metals was one order of magnitude higher than that of PAHs and the concentration and detection frequency of OCPs and PCBs were considerably lower than those of metals and PAHs. The lifetime excess cancer risk (LECR) for carcinogens in PM2.5 exceeded deminimis risk (1 x 10(-6)) as 1.33-3.44 x 10(-6) (at 5th-95th percentile) as Cr(VI), As, and Cd showed high contributions.
