This work has been developed to examine the level of non-dioxin-like (ndl) PCBs (28, 52, 101, 138, 153 and 180) in (a) ten different freshwater fish species from the Danube river, (b) two sampling points: up and downstream of the industrial zone of the city of Pancevo (ecological hot spot in Serbia) and (c) two time points i.e., in 2001 and 2006. Obtained results would serve to analyse spatial, temporal and congener profile characteristics of ndl PCBs cumulated in fish tissues due to environmental pollution. Sixty-four samples of the following species were collected: wels (Silirus glanus), pike (Esox lucius), bream (Abramis brama), crucian carp (Carassius carassius), pike pearch (Stizostedion lucioperca), barbel (Barbus barbus), tench (Tinca tinca), sterlet (Acipenser ruthenus L.), common carp (Cyprinus carpio) and bighead carp (Hypophthalmichthys nobilis). Gas chromatography coupled with electron capture detector was used for analysis of ndl PCBs. Total ndl PCBs content in upstream samples ranged from 2.7 to 98.1 ng/g and from 4.9 to 68.3 ng/g in 2001 and 2006, respectively. During the 5 years, ndl PCBs content increased significantly in downstream samples i.e., ndl PCBs varied from 13.7 to 46.1 ng/g and from 14.4 to 107.2 ng/g in 2001 and 2006, respectively. PCBs 138 and 180 were predominant congeners in 2001, while in 2006 the most abundant PCB congeners were 138 and 153. In 2006, the presence of PCB 28 and PCB 52 has indicated a recent contamination event. Data on continual monitoring of PCBs in all relevant environmental compartments together with appropriate biomonitoring data are expected to give comprehensive insight into the fate and behaviour profile of these contaminants.
本研究旨在检测十种不同的多瑙河淡水鱼（a）、两个采样点（b）（即城市潘切沃工业区上下游）和两个时间点（c）（即 2001 年和 2006 年）的非二恶英类多氯联苯（ndl pcbs）（28、52、101、138、153 和 180）的水平。所得结果将用于分析由于环境污染而在鱼类组织中累积的 ndl pcbs 的空间、时间和同系物特征。采集了以下 64 种鱼类样本：欧西尼亚鲶（Silirus glanus）、梭鲈（Esox lucius）、鲤鱼（Abramis brama）、鲫鱼（Carassius carassius）、拟鲤（Stizostedion lucioperca）、赤眼鳟（Barbus barbus）、丁鱥（Tinca tinca）、施氏鲟（Acipenser ruthenus L.）、鲤鱼（Cyprinus carpio）和鳙鱼（Hypophthalmichthys nobilis）。采用气相色谱-电子俘获检测法分析 ndl pcbs。2001 年和 2006 年，上游样品中 ndl pcbs 的总含量分别为 2.7 至 98.1ng/g 和 4.9 至 68.3ng/g。在这 5 年期间，下游样品中 ndl pcbs 的含量显著增加，2001 年和 2006 年分别为 13.7 至 46.1ng/g 和 14.4 至 107.2ng/g。2001 年，pcbs138 和 180 是主要同系物，而 2006 年，最丰富的 pcb 同系物是 138 和 153。2006 年，pcb28 和 pcb52 的存在表明最近发生了污染事件。预期对所有相关环境成分中 pcb 的持续监测数据以及适当的生物监测数据将全面了解这些污染物的命运和行为特征。
