The residues of DDT and its analogs were estimated in a number of cod liver samples (Gadus morhua) collected at six sampling sites off the Atlantic Coast of the Maritime Provinces of Canada during the summer of 1971. The residue levels indicated widespread distribution of DDT over the entire region sampled. Variations in the relative contributions of p,p'-DDE and p,p'-DDT to the total DDT residues (xiDDT) were noted and the tendency for these residues to preferentially accumulate in lipid rich tissues was demonstrated. The residue levels found in cod livers were compared to the residue levels determined in cod flesh taken from some of the same specimens and also to residue levels in commercially refined cod liver oils. Samples of each of these types were stored at -29 degrees C and analyzed in 1973 for DDT and PCB simultaneously. The xiDDT residues determined by both methods of analysis were compared.
1971年夏季，在加拿大滨海诸省大西洋沿岸的六个采样点采集了若干鳕鱼（大西洋鳕）肝脏样本，对其中滴滴涕及其类似物的残留量进行了估算。残留量水平表明滴滴涕在整个采样区域广泛分布。注意到p,p'-滴滴伊和p,p'-滴滴涕在总滴滴涕残留量（∑DDT）中的相对贡献存在差异，并且证明了这些残留量有优先在富含脂质的组织中积累的趋势。将鳕鱼肝脏中的残留量水平与取自部分相同样本的鳕鱼肉中的残留量水平以及商业精制鱼肝油中的残留量水平进行了比较。每种类型的样本均储存在-29摄氏度下，并于1973年同时分析其中的滴滴涕和多氯联苯。对两种分析方法测定的∑DDT残留量进行了比较。
