英文摘要	A novel method has been developed for the determination of trace polychlorinated biphenyls congeners in the biota samples and water. The method includes liquid-liquid extraction or ultrasonic extraction, cleanup of sulfuric acid silica column separation, separation of florisil column and analyses of capillary gas chromatography equipped with Ni-63 electron-capture detection system (mu-ECD). Conditions for cleanup of sulfuric acid silica gel column and separation of florisil column were optimized. The average recoveries were 82% similar to 115% for water, 75% similar to 135% for biotic samples, respectively. The limits of detection were 0.009 similar to 15.3 ng/L for feeding water, from 0.02 to 96.9 ng/g for the biota samples, respectively, the relative standard deviations were all below 6.9%. The method was successfully used for the analyses of trace polychlorinated biphenyls congeners in Xenopus laevis and. feeding water. The results of quality control show that the method merits the reliable investigation.
