Investigation of Chlorophenols in Surface Water of Pearl River Estuary Area
Field investigation is conducted in the Pearl River Estuary area,involving the surface water sampling and analysis of phsico-chemical parameters including chlorophenols(CPs)using solid phase micro-extraction(SPME)and GS-MS.The result indicates that the detection rate for four species of CPs is as high as 98.75% with the peak value being found in the Hengmen River.In general,it seems that the residue of PCs in this area poses low risk to the environment and human beings.In addition,the result of multiple regression shows that there exists a significant negative correlation between content of CPs and the contents of total iron and total manganese.
