| 摘 要： | 采用ＨＰＬＣ和ＧＣ／ＭＳ法对六六六热解废渣中的ＰＣＤＤｓ和ＰＣＤＦｓ进行了测定，使用此种方法，于废渣中检出了所有２，３，７，８－取代的同系物。此外，还根据各ＣＤＤｓ，ＣＤＦｓ的毒性当量因子ＴＥＦｓ，计算了废渣的毒性当量ＴＥＱｓ，约为６１２－９２４μｇ／ｇ。分析表明，ＯＣＤＤ是含量最丰富的导构体，而１，２，３，４，６，７，８－ＨｐＣＤＤ，１，２，３，４，６，７，８－ＨｐＣＤＦ和１，２，３，４，７，８

| Abstract: | PCDDs and PCDFs in thermolysis waste of HCH were analyzed by HPLC and GC/MS. All of the 2,3,7,8-substituted PCDDs and PCDFs were detected. According to the toxic equivalency factors of individual isomers(TEFs) ,the toxic equivalents(TEQs) of the waste were estimated, which was in the range of 612-924/ug/g. Results indicated that OCDD was the most aboundant congner while 1,2,3,4,6,7, 8-HpCDD ,1,2,3,4,6,7, 8-HpCDF and 1,2.3,4,7, 8-HxCDF were considered as the most important components which constituted the most parts of the TEQs. |
