The occurrence of polychlorinated biphenyls (PCBs) was investigated in the Soulou stream in the area of Eordea, northwestern Greece, receiving the effluents of two lignite burning power plants. The study was carried out after an accidental fire in one of the power plants during which losses of an amount of Aroclor 1232 were recorded. PCBs were determined in water and sediment samples collected from the wastewater treatment unit of the power plant and various points across the stream. Concentrations of PCBs were in the same order of magnitude as in other surface waters and sediments previously found in the Greek territory. The sum concentrations of seven PCBs (#28, #52, #101, #118, #138, #153, #180) varied between 94 and 206 ngl(-1) in waters, and between 67 and 500 ngg(-1) in sediments. Profile analysis of PCB congeners revealed large differences between waters and sediments, showing also significant dissimilarity with the profile of Aroclor 1232.
对希腊西北部埃奥利亚地区苏卢河进行了多氯联苯（PCBs）污染情况调查，该河流接纳了两座褐煤发电厂的废水。这项研究是在其中一座发电厂发生意外火灾后开展的，火灾期间记录到一定量的氯丹1232泄漏。对从发电厂废水处理单元以及河流各点采集的水样和沉积物样本进行了多氯联苯测定。多氯联苯的浓度与希腊境内此前在其他地表水和沉积物中发现的浓度处于同一数量级。水中七种多氯联苯（#28、#52、#101、#118、#138、#153、#180）的总浓度在94至206纳克/升之间，沉积物中的浓度在67至500纳克/克之间。多氯联苯同系物的分布分析显示，水和沉积物之间存在很大差异，与氯丹1232的分布也有显著不同。
