The determination of polychlorinated biphenyls (PCBs) in water, sediment and fish samples from the Czech Republic was carried out using high resolution gas chromatography with electron capture detection. PCBs concentrations in water and sediment samples were rather low and corresponded with the findings from some prior studies. On the other hand, investigated samples of fish tissue were highly contaminated (on average 1.3-266 ng/g fat for individual PCBs), thus, a continuing contamination of fish species with PCBs was proved.
采用带电子捕获检测的高分辨率气相色谱法对来自捷克共和国的水、沉积物和鱼类样本中的多氯联苯（PCBs）进行了测定。水和沉积物样本中的多氯联苯浓度相当低，与一些先前研究的结果相符。另一方面，所调查的鱼类组织样本受到了高度污染（单个多氯联苯的平均含量为1.3 - 266纳克/克脂肪），因此，证明了鱼类物种持续受到多氯联苯的污染。
