Persistent organochlorines, such as polychlorinated biphenyls, including coplanar congeners and DDT compounds, were measured in the liver of a teleost species: namely, Lophius budegassa. The mean concentrations of PCBs (1249 ng/g wet wt) were comparable with DDTs mean levels (1459 ng/g wet wt). Among DDTs the compound found at the highest concentration was p,p'-DDE representing 76% of the total DDT burden. The PCB profiles were dominated by congeners 153, 180, and 138 accounting for 49.8%, 16.0% and 13.7% of the total PCBs. The total 2,3,7,8-TCDD toxic equivalent (TEQs) of six coplanar PCBs, including mono- and non-ortho congeners, was 0.98 pg/g wet wt. The congeners with highest TEQs values were non-ortho-congeners followed by mono-ortho ones.
在一种硬骨鱼（即大西洋狼鱼）的肝脏中，对持久性有机氯进行了测量，这些有机氯包括多氯联苯（PCB），其中有共面同系物和滴滴涕（DDT）化合物。多氯联苯的平均浓度（1249纳克/克湿重）与滴滴涕的平均水平（1459纳克/克湿重）相当。在滴滴涕化合物中，浓度最高的是对，对'-滴滴伊，占总滴滴涕含量的76%。多氯联苯的谱图以同系物153、180和138为主，分别占多氯联苯总量的49.8%、16.0%和13.7%。六种共面多氯联苯（包括单邻位和非邻位同系物）的总2,3,7,8-四氯二苯并对二恶英毒性当量（TEQs）为0.98皮克/克湿重。毒性当量值最高的同系物是非邻位同系物，其次是单邻位同系物。
