摘要在中国北部的济南、包头采集了PM2.5样品。测定了9种重金属(HMS)(铬、砷、镉、锑、铅、镍、铜、锌、锰)和2种持久性有机污染物[多氯二苯并对二恶英和二苯并呋喃(PCDD/FS)和二恶英类多氯联苯(DL-PCBS)](POPs)的含量。两个城市与PM2.5结合的HMS浓度均表现出明显的季节特征。济南市砷、镉、锑、铅、铜、锌含量最高出现在采暖季，铬、镍、锰含量最高出现在风季。包头市PM2.5HMS浓度大小顺序为：采暖季 >；非采暖季 ； >； 多风季。在这两个城市，采暖季节的浓度最高，分别为17种二恶英和12种二氯联苯。只有一小部分出现在多风季节。除非采暖季节外，包头市Σ二恶英和Σ二恶英含量均远高于济南市。致癌金属浓度对成人的健康风险大约是儿童的两倍。值得注意的是，包头市成年人的铬风险略高于临界值。
Abstract We collected PM2.5 samples in the cities of Jinan and Baotou, North China. Concentrations of 9 heavy metals (HMs) (Cr, As, Cd, Sb, Pb, Ni, Cu, Zn, Mn) and 2 persistent organic pollutants [polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls, (DL-PCBs)] (POPs), were determined. The concentrations of PM2.5-bound HMs exhibited apparent seasonal characteristics in both cities. In Jinan, the highest levels of As, Cd, Sb, Pb, Cu, Zn occurred in the heating season, while, the levels of Cr, Ni, Mn peaked in the windy season. In Baotou, The order of concentrations of HMs in PM2.5 was as follows: heating season > non-heating season > windy season. In both cities, the heating season had the highest concentrations of 17 PCDD/Fs and 12 DL-PCBs. Only a small amount of them occurred in the windy season. In Baotou, ΣPCDD/Fs and ΣDL-PCBs levels were much higher than in Jinan, except in the non-heating season. The health risk of carcinogenic metal concentrations for adults was approximately twice than that for children. Notably, the Cr risk for adults slightly exceeded the critical value in Baotou.
