%X The concentrations of polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides in surface sediments from rivers of the Pearl River Delta and Estuary were measured,based on USEPA 8000 methods and under quality assurance and quality control (QA/AC).The surface sediments from the Guangzhou channel and inside Macao harbor contained the highest concentration of PAHs and organochlorine pesticides.The concentrations of contaminants were decreasing obviously after flowing into the Zhizi Ocean.The surface sediments from the western sites in the Pearl River Estuary were contaminated much higher than those from the eastern sites.The surface sediments from the West River contained relatively elevated concentrations of priority PAHs.The sources of PAHs in surface sediments were also discussed preliminarily.
