摘    要:于2001年春季使用大流量采样器对深圳市气相和颗粒相空气样品进行采集,分析其中的多氯联苯(PCBs)的含量和分布,计算出PCBs的氯数分布和气/固两相之间的分配,并将所得结果与国外的同类研究进行了对比。结果表明,深圳市空气中PCBs的质量浓度处于中等污染水平;与国外同类研究相比,深圳市空气中颗粒相PcBs的质量浓度贡献远高于其他地区的对应值;lgKp与lgPL^0。线性回归分析表明,深圳市空气中的PCBs接近气/固分配的平衡状态。

关 键 词:PCBs  气相和颗粒相  氯数分布  气/固分配

Abstract:Air samples were collected using high-volume sampler in Shenzhen city in the spring of 2001. Based on the concentrations and congener-specific distributions of polychlorinated biphenyls (PCBs)in gas and particle phase, the homologue profiles and gas-particle partitioning of PCBs were calculated and compared with similar studies in other countries. The results showed that the atmospheric level of PCBs was moderate during the sampling period. Concerning the phase distribution, the contribution of particle-phase of PCBs to the total atmospheric PCBs was much higher in Shenzhen than in other countries. The results of lg K_p vs lg P_L~0 showed that the phase distribution of atmospheric PCBs in Shenzhen was close to the state of equilibrium.
Keywords:PCBs  gas and particle phase  homologue profile  gas-particle partitioning
