摘　　要：采用HPLC和GC/MS的方法,对国产PCP及其钠盐中的PCDDs,PCDFs进行了分析.测定了所有2,3,7,8-取代同系物.此外,还根据各CDDs,CDFs的毒性当量因子TEFs,计算了其毒性当量I-TEQs,分别为142,92ng·g^(-1).在前述基础上,估算了由于PCP及其钠盐的应用,引起的PCDDs,PCDFs环境输入.约为240kg/a.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.
