| 摘 要： | 研究了珠江三角洲地区大气中多氯联苯的含量与分布.利用大气被动采样装置,共设立了包括香港在内的珠江三角洲21个大气被动采样点,样品采样时间为2005-08-15～2005-10-14.结果表明,珠三角内地的佛山(2000pg·m-3)是PCBs的高污染地区,内地采样点PCBs含量范围260～2000pg·m-3,平均值670pg·m-3.香港PCBs含量范围170～470pg·m-3,平均值300pg·m-3.香港每个采样点的PCBs含量都接近平均值,含量比较低.珠三角大气中PCBs含量与世界其它地区相比属中度污染区域.结果也表明,PUF大气被动采样器可很好地运用于区域大气PCBs污染分布与特征的对比研究. |

| Abstract: | The article research concentration and distribution of atmospheric polychlorinated biphenyls from the Pearl River Delta (PRD) using PUF passive sampling technique. Sampling was conducted at the same time at twenty-one passive sampling sites for consecutive 56 day from August 2005 to October 2005. The results showed middle contaminated levels of PCBs were found in PRD in comparison with other places in the world. Higher contaminated site located FoShan (2 000 pg x m(-3)) in PRD. Concentration range of PCBs are 260 - 2 000 pg x m(-3) and average valuable 670 pg x m(-3) in PRD, 170 - 470 pg x m(-3) and 300 pg x m(-3) in HK. It is obvious that distribution of PCBs in PRD is higher and lower in HK. The results demonstrated that PUF-PAS technique can be used in the monitoring of PAHs in the atmosphere at a regional or global scale. |
