Abstract

The composition and loads of organochlorine pesticides (DDTs, HCBs, HCHs, CHLs) and polychlorinated biphenyls (PCBs) transported with the Vistula River waters to the Gulf of Gdansk in 1991-1992 has been determined. The method of organochlorine compounds measurement was capillary gas chromatography with ECD after adsorption of the analyte on Ambertlite XAD-2, resin and subsequent elution, clean-up and HPLC fraction of the extract. The concentrations of DDTs, HCBs, HCHs, CHLs and PCBs in the Vistula River water ranged between 120-840, 7.6-52, 1600-410,000, 8.1-57 and 120-300 pg/l, respectively. During 12 months period of the study the total load of DDTs, HCBz, HCHs, CHLs and PCBs transported with the Vistula River water to the Gulf of Gdańsk was assessed on 10.54, 0.73, 1377, 0.38 and 5.02 kg, respectively.

摘要

已测定了1991 - 1992年期间随维斯瓦河河水输送至格但斯克湾的有机氯农药（滴滴涕、六氯苯、六氯环己烷、氯丹）和多氯联苯的成分及含量。有机氯化合物的测定方法是采用毛细管气相色谱法和电子捕获检测器，先将分析物吸附在Amberlite XAD - 2树脂上，随后进行洗脱、净化以及提取物的高效液相色谱分级分离。维斯瓦河水中滴滴涕、六氯苯、六氯环己烷、氯丹和多氯联苯的浓度分别在120 - 840、7.6 - 52、1600 - 410000、8.1 - 57和120 - 300皮克/升之间。在为期12个月的研究期间，随维斯瓦河河水输送至格但斯克湾的滴滴涕、六氯苯、六氯环己烷、氯丹和多氯联苯的总负荷分别评估为10.54、0.73、1377、0.38和5.02千克。
