摘要:
利用大流量主动采样器,于2010年冬、夏两季对深圳市13个点位大气多氯联苯(polychlorinated biphenyls, PCBs)分别进行监测.结果显示,冬季采样期间,大气PCBs质量浓度为3.5~104.5 pg/m3,平均为29.3 pg/m3;类二恶英PCBs(dioxin-like PCBs, dl-PCBs)的质量浓度为0.2~2.6 pg/m3,平均为1.0 pg/m3.夏季采样期间,大气PCBs质量浓度为10.7~135.7 pg/m3,平均为44.6 pg/m3;二恶英类PCBs质量浓度为1.2~4.8 pg/m3,平均为2.2 pg/m3.深圳市大气PCBs组成以三氯代PCBs和四氯代PCBs为主,其对∑ρ(PCBs)的贡献率为73.6%~91.4%.深圳市大气PCBs主要来自PCBs产品在使用过程中的遗弃、泄露和排放,部分源自人类生产活动过程无意产生. 国产PCBs产品、进口PCBs产品和废弃物焚烧对深圳市大气PCBs的贡献分别为50%、10%和14%.
Abstract:
Ambient air samples were collected for the analysis of polychlorinated biphenyls by using high-volume samplers in thirteen locations in Shenzhen during January and June 2010, respectively. The results indicated that, PCBs and dioxin-like PCBs concentration were in the range of 3.5—104.5 pg/m3 (average 29.3 pg/m3) and 0.2—2.6 pg/m3 (average 1.0 pg/m3) during the winter sampling season, respectively. During the summer sampling season, they were in the range of 10.7—135.7 pg/m3 (average 44.6 pg/m3) and 1.2—4.8 pg/m3 (average 2.2 pg/m3), respectively. The PCBs were dominated by tri- and tetra-PCBs, which accounted for 73.6%—91.4% of the ∑ρ(PCBs). The sources of PCBs were mainly from the local emissions of historical-used PCBs products, and some were unintentionally-produced PCBs from solid waste incineration and other thermal processes. Results indicate that Chinese PCBs product, imported PCBs product and solid waste incinerator contribute to 50%, 10% and 14% of the total PCBs released, respectively.
