| Abstract: | A total of 146 topsoil samples were collected from the core area of Ningdong energy and chemical industry base,and 6 phenolic pollutants for priority control were detected. The pollution degree and health risks of phenolic pollutants were evaluated,their spatial distribution and source were analyzed. The results show that：2,4-dichlorophenol and 2,4,6-trichlorophenol（TCP） are in a clean level,but some areas are heavily polluted by pentachlorophenol;The risk of phenol,2,4-dichlorophenol and TCP are acceptable,while the risk of pentachlorophenol is unacceptable in some areas;The main sources of phenol,4-nitrophenol,m-cresol and 2,4-dichlorophenol are from traffic,the sources of TCP and pentachlorophenol are mainly from industrial activities. |
