초록

POPs in sediments and soil in the PRD are comparable to or much higher than those reported in other regions. Some sites may be classified as POPs- polluted with high ecological risks. Large-scale land transform in the process of regional urbanization may facilitate the transfer of POPs in the soil to the sedimentary system by enhancing the soil run-off. Urban atmospheric PCBs in PRD are found to be less than some of the North American or European urbans, but PAHs are significantly higher. The center of the PRD has been the major source area of PAHs and organochlorine pesticides in the PRD. The northern part of the PRD serves as a regional sink for the air particulates and affiliated POPs.
