对2001年和2002年在哈萨克斯坦、阿塞拜疆、土库曼斯坦和伊朗里海沿岸水域采集的5种中华鲟进行了有机氯化合物（OCs）检测，了解其污染状况和积累特征。在检测的OCs中，DDT （DDT及其代谢物）的浓度在所有鲟样本中都占主导地位，以脂质重量为基础的浓度范围为73 ~ 31,000 ng/g，其次是多氯联苯、chl、HCHs、HCB、狄氏剂、TCPMOH和七氯环氧化物。白鲸（Huso Huso）的OCs浓度最高。当比较同一物种之间的残留水平时，来自阿塞拜疆和哈萨克斯坦的鲟鱼的有机碳残留量最高，而土库曼斯坦的最低。然而，HCHs、狄氏剂和环氧七氯在鲟鱼体内的浓度表现出较小的地理变异性。
Organochlorine compounds (OCs) were determined in the five species of sturgeons collected from coastal waters of Caspian Sea in Kazakhstan, Azerbaijan, Turkmenistan and Iran during 2001 and 2002 to understand their status of contamination and accumulation features. Among OCs examined, concentrations of DDTs (DDT and its metabolites) were predominant in all the sturgeon samples with concentrations ranging from 73 to 31,000 ng/g on lipid weight basis, followed by PCBs, CHLs, HCHs, HCB, dieldrin, TCPMOH, and heptachlor epoxide in order. The concentrations of OCs in beluga (Huso huso) were the highest among all the five species. When comparing residue levels among same species, OC residues were highest in sturgeons from Azerbaijan and Kazakhstan and lowest in Turkmenistan. However, the concentrations of HCHs, dieldrin, and heptachlor epoxide in sturgeons showed less geographical variability.
