对欧洲鳗鱼和鲑鱼样品进行了分析，以确定非二恶英类多氯联苯(NDL-PCbs)、多氯二苯并二恶英(PCDDs)和多氯二苯并呋喃(PCDFs)、类二恶英多氯联苯(DL-PCbs)和溴化多溴二苯醚(PBDEs)的水平，以评估流经罗马(意大利)的市区沿线台伯河的污染程度。所有样品都提供了可检测到的所分析化学物质的水平，并在同系物组成和总浓度方面显示出特定物种的差异。平均而言，欧洲鳗鱼的价值最高。在该物种中，二恶英类化合物总量(WTO-TEQs)超过了相关的最高水平(MLS)。非邻位多氯联苯约占WHO-TEQ毒理学潜力的80%，而NDL-多氯联苯和多溴二苯醚的浓度似乎与存在非点源的其他受污染的水生生态系统中测定的值相符。鱼类组织中确定的污染模式似乎反映了一般污染源的影响(S)。
European eel and chub samples were analyzed to determine the levels of non-dioxin-like polychlorobiphenyls (NDL-PCBs), polychlorodibenzodioxins (PCDDs) and polychlorodibenzofurans (PCDFs), dioxin-like PCBs (DL-PCBs), and brominated polybromodiphenyl ethers (PBDEs) in order to evaluate the extent of contamination of the river Tiber along the urban tract through the city of Rome (Italy). All samples presented detectable levels of the chemicals analyzed, and exhibited species-specific differences in terms of congener composition and total concentrations. On average the European eel presented the highest values. In this species the dioxin-like compound sums (WTO-TEQs) exceeded the pertinent maximum levels (MLs). Non-ortho PCBs constituted approximately 80% of WHO-TEQ toxicological potential whereas NDL-PCB and PBDE concentrations appeared to match values determined in other polluted aquatic ecosystems where non-point contamination sources were present. The contamination patterns determined in fish tissues seemed to reflect the impact of generic contamination source(s).
