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.
