DDT and polychlorinated biphenyl (PCB) compounds were found in blubber tissue samples of 12 North American fin-back whales collected in 1970 and 1971. Concentrations of DDT and metabolites ranged up to 2.557 ppm, while the highest PCB concentration was 0.185 ppm Gas chromatographic results were confirmed by chemical derivatization.
在1970年和1971年采集的12头北美长须鲸的鲸脂组织样本中发现了滴滴涕(DDT)和多氯联苯(PCB)化合物。滴滴涕及其代谢物的浓度高达2.557 ppm,而多氯联苯的最高浓度为0.185 ppm。气相色谱结果通过化学衍生化得到证实。
