In the first review of potentially toxic elements (PTEs) in fish in water ecosystems in Serbia, 40 studies related to fish contamination with PTEs were identified and evaluated. Studies of concentrations of PTEs in fish tissues covered 28 ecosystems (108 localities). The main studied river ecosystems were the Danube and the Sava, and the Međuvršje reservoir was the most studied standing water ecosystem. Among the most studied fish species were catfish (Silurus glanis), followed by pikeperch (Sander lucioperca), bream (Abramis brama), carp (Cyprinus carpio), and barbel (Barbus barbus). There were 48 "hot spot" sampling sites where concentrations of Hg, Cd, Pb, As, Ni, Fe, and/or Cu exceeded the maximum permitted concentrations (MPCs) prescribed by legislation. Elevated concentrations of these elements were the most detected in fish species sampled in the Danube, Sava, and rivers belonging to the Velika Morava basin. Hg concentrations were the most common above MPC in muscle tissue of species sampled from the Danube and Sava rivers. On the other hand, we can single out the species Vimba bream (Vimba vimba), sampled in Danube River in Zemun near Belgrade, as the safest species for human consumption due to the largest number of elements in fish meat below detection limits. Finally, having in mind all the criteria prescribed by U.S. EPA (2000), we identify and recommend two predatory fish species pikeperch (S. lucioperca) and catfish (S. glanis), and bottom-feeding fish species barbel (B. barbus) as bioindicators of PTEs contamination in Serbian waters.
在对塞尔维亚水生态系统中鱼类潜在有毒元素（PTEs）的首次综述中，确定并评估了40项与鱼类受PTEs污染相关的研究。对鱼类组织中PTEs浓度的研究覆盖了28个生态系统（108个地点）。主要研究的河流生态系统是多瑙河和萨瓦河，梅杜尔什耶水库是研究最多的静水生态系统。研究最多的鱼类品种有鲶鱼（欧洲六须鲶），其次是梭鲈（大眼梭鲈）、鲷鱼（欧鳊）、鲤鱼（鲤）和鲃鱼（钝吻鲃）。有48个“热点”采样点，汞、镉、铅、砷、镍、铁和/或铜的浓度超过了法律规定的最大允许浓度（MPC）。在多瑙河、萨瓦河以及大摩拉瓦河流域的河流中采样的鱼类品种中，这些元素的浓度升高最为常见。在多瑙河和萨瓦河采样的物种肌肉组织中，汞浓度最常超过MPC。另一方面，我们可以选出在贝尔格莱德附近泽蒙的多瑙河采样的细纹鳊（细纹鳊）作为人类消费最安全的物种，因为鱼肉中低于检测限的元素数量最多。最后，考虑到美国环境保护局（2000年）规定的所有标准，我们确定并推荐两种捕食性鱼类梭鲈（大眼梭鲈）和鲶鱼（欧洲六须鲶），以及底栖鱼类鲃鱼（钝吻鲃）作为塞尔维亚水域PTEs污染的生物指示物。
