We summarized available data concerning contamination of the Czech part of the Elbe River by mercury and assessed the potential risks to humans connected with the consumption of contaminated fish. Total mercury concentrations were evaluated in dorsal muscle of chub (Squalius cephalus) and bream (Abramis brama) that were collected at 11 sampling sites in the period from 1991 to 2016. Significant differences among sites were found for both species. The highest contamination was observed near the non-ferrous Kovohute metal works at Celakovice and also downstream from the Spolana chemical plant at Neratovice. A significant decline in contamination with time (concentrations decreasing from 1.65 to 0.22 mg kg⁻¹; p = 0.004) was revealed in chub downstream from the Spolana plant. Calculated hazard indices (HIs) were below 1, therefore, adverse health effects on the general Czech population connected with the consumption of fish from the Elbe River were not expected.

我们总结了有关汞污染易北河捷克部分的现有数据，并评估了与食用受污染鱼有关的对人类的潜在风险。对1991年至2016年期间在11个采样点采集的（Squalius cephalus）和（Abramis brama）的背肌中的总汞浓度进行了评估。发现这两个物种的位点之间存在显着差异。在Celakovice的有色Kovohute金属厂附近以及Neratovice的Spolana化工厂的下游，污染程度最高。污染随着时间的推移而显着下降（浓度从1.65 mg kg ^-1降至0.22 mg kg ^-1；p = 0.004）在Spolana工厂下游的中发现。计算的危害指数（HIs）低于1，因此，预计与易北河鱼类消费相关的对捷克总人口的不利健康影响。
