Polychlorinated biphenyls including coplanar congeners and DDT compounds were measured in different organs and tissues (liver, kidney, lung and muscle tissue) of loggerhead turtles Caretta caretta from the eastern Mediterranean Sea. The highest levels of these compounds were found in liver (PCBs: 52.32 ng/g; DDTs: 18.27 ng/g), followed by kidney (PCBs: 19.05 ng/g; DDTs: 5.70 ng/g), lung (PCBs: 12.75 ng/g; DDTs: 3.76 ng/g ) and muscle tissue (PCBs: 4.65 ng/g; DDTs: 1.45 ng/g). PCBs revealed a profile dominated by hexa-, penta- and hepta-chlorinated congeners, while among DDTs, the compound in the greatest concentration was p,p'-DDE, (liver: 85.2%, kidney: 93.6%, lung: 86.4%, muscle tissue: 93.2%). The estimated toxic equivalents (pg TEQs/g wet wt) of non- and mono-ortho PCBs were in the range of 1.54-5.86 pg TEQs/g wet wt. Non-ortho coplanar PCB 77 accounted for more than 90% of the total TEQs leaving to mono-ortho only 2.6-6.2%.
对来自地中海东部的蠵龟（Caretta caretta）的不同器官和组织（肝脏、肾脏、肺和肌肉组织）中的多氯联苯（包括共面同系物）和滴滴涕化合物进行了测量。这些化合物在肝脏中的含量最高（多氯联苯：52.32纳克/克；滴滴涕：18.27纳克/克），其次是肾脏（多氯联苯：19.05纳克/克；滴滴涕：5.70纳克/克）、肺（多氯联苯：12.75纳克/克；滴滴涕：3.76纳克/克）和肌肉组织（多氯联苯：4.65纳克/克；滴滴涕：1.45纳克/克）。多氯联苯显示出以六氯、五氯和七氯同系物为主的分布特征，而在滴滴涕中，浓度最高的化合物是p,p'-滴滴伊（肝脏：85.2%，肾脏：93.6%，肺：86.4%，肌肉组织：93.2%）。非邻位和单邻位多氯联苯的估计毒性当量（皮克毒性当量/克湿重）在1.54 - 5.86皮克毒性当量/克湿重范围内。非邻位共面多氯联苯77占总毒性当量的90%以上，单邻位仅占2.6 - 6.2%。
