| 摘 要： | 本研究测定了青海省西宁市与海西蒙古族藏族自治州天峻县夏、冬两季大气颗粒物中有机氯农药(OCPs)和类二噁英多氯联苯(DL-PCBs)的浓度水平.结果表明,青海省大气颗粒物中OCPs主要为DDTs、HCHs.西宁市DDTs和HCHs的平均水平分别为:35 pg·m-3、5.9 pg·m-3(夏季)和93 pg·m-3、11 pg·m-3(冬季),天峻县DDTs和HCHs的平均水平分别为:83pg·m-3、6.4 pg·m-3(夏季)和28 pg·m-3、6.7 pg·m-3(冬季).与亚洲其它地区相比,青海省大气颗粒物中OCPs处于较低水平.西宁市大气颗粒物中DL-PCBs的平均水平分别为:0.52 pg·m-3(夏季),0.99 pg·m-3(冬季),天峻县为:0.58 pg·m-3(夏季)、0.52 pg·m-3(冬季).西宁市夏、冬两季OCPs的平均水平均大于天峻县,而两地DL-PCBs的平均水平相当.本研究中高原地区DL-PCBs的分布特点及变化规律与极地地区的研究相比存在一定的相似性,而DDTs和HCHs则存在差异性.

| Abstract: | The levels of OCPs and DL-PCBs in the atmospheric particulates of Xining city and Tianjun county in Qinghai province were determined. DDTs and HCHs were the main component of OCPs in the atmospheric particulates. The average levels of DDTs and HCHs in the atmospheric particulates of Xining city were 35 pg·m-3 and 5.9 pg·m-3 in summer and 93 pg·m-3 and 11 pg·m-3 in winter, respectively. In Tianjun county, they were 83 pg·m-3 and 6.4 pg·m-3 in summer and 28 pg·m-3 and 6.7 pg·m-3 in winter, respectively. Compared with other Asian areas, the average levels of them in Qinghai province were lower. Meanwhile, the average levels of DL-PCBs in Xining city were 0.52 pg·m-3 in summer and 0.99 pg·m-3 in winter, respectively, and in Tianjun county were 0.58 pg·m-3 in summer and 0.52 pg·m-3 in winter, respectively. The average levels of OCPs in summer and winter of Xining city were higher than those in Tianjun county, but the average levels of DL-PCBs in two cities were similar. Compared with the polar region, the distribution principles of DL-PCBs in the plateau area were certainly similar, while HCHs and DDTs were different. |
