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.
2001年至2002年期间，在哈萨克斯坦、阿塞拜疆、土库曼斯坦和伊朗里海沿海水域采集了五种鲟鱼样本，测定其中有机氯化合物（OCs）的含量，以了解其污染状况和积累特征。在所检测的有机氯化合物中，滴滴涕（DDT及其代谢物）在所有鲟鱼样本中的浓度最高，以脂质重量计，浓度范围为73至31,000 ng/g，其次依次为多氯联苯、氯丹、六氯环己烷、六氯苯、狄氏剂、三氯杀螨醇和环氧七氯。在所有五个物种中，大白鲟（Huso huso）体内的有机氯化合物浓度最高。在比较同一物种的残留水平时，阿塞拜疆和哈萨克斯坦的鲟鱼体内有机氯残留量最高，土库曼斯坦的最低。然而，鲟鱼体内六氯环己烷、狄氏剂和环氧七氯的浓度在地理上的变化较小。
