Abstract

Toxaphene residues in cod liver and fish oil samples from different countries have been analyzed by HRGC-ECD and HRGC-MS as well as with multidimensional gas chromatography. The results have been compared to patterns obtained by photolysis and microbial degradation of selected single chlorobornanes and technical toxaphene. Enantiomeric ratios of the components Parlar #44 and #62 showed significant deviations from 1, indicating metabolism in cod fish and perhaps other species at least for some congeners. Parlar #50 was found to be a racemate, which corresponds to its known stability under biotic and abiotic conditions.

摘要

已采用高分辨率气相色谱 - 电子捕获检测器（HRGC - ECD）、高分辨率气相色谱 - 质谱联用仪（HRGC - MS）以及多维气相色谱法对来自不同国家的鳕鱼肝和鱼油样本中的毒杀芬残留量进行了分析。已将这些结果与通过选定的单氯莰烷和工业用毒杀芬的光解及微生物降解所获得的模式进行了比较。成分Parlar #44和#62的对映体比例显示出与1有显著偏差，这表明在鳕鱼以及可能至少某些同系物的其他物种中发生了代谢作用。已发现Parlar #50是一种外消旋体，这与其在生物和非生物条件下已知的稳定性相符。
