PCDDs and PCDFs in Chinese pentachlorophenol and sodium pentachlorophenate were analyzed by using HPLC and GC/MS. All of the 2 , 3,7, 8-substituted PCDDs and PCDFs were detected. According to the toxic equivalency factor of individual isomers (TEFs), the Toxic equivalents (I-TEQs) of the samples were estimated. Assuming that 10 000 fa-1 of sodium pentachlorophenate was used for prevention of schistosomiasis in China, The total environmental input for PCDDs and PCDFs would account for about 240kg.
