“…In our research, Pb and Cd concentrations in fish muscle were below detection limit in most of analyzed samples and the mean concentrations of these metals were similar to those of some unpolluted areas (Dusek et al, 2005;Yilmaz et al, 2007;Petkovsek et al, 2012;Yancheva, Stoyanova, Velcheva, Petrova, & Georg ieva, 2014). That is in accordance to very low Pb and Cd concentrations recorded in sediments of Skadar Lake (Kastratovic, Jacimovic, Bigovic, Djurovic, & Krivokapic, 2016).…”

“…Th is metal predo minantly accumulates in fish muscle (Wiener, Krabbenhoft, Hein z, & Scheuhammer, 2003). It is one of the few metals known to bio magnify through food webs; therefore, carnivorous fish species usually contain the highest amounts of Hg as a top predators in the aquatic food chains (Dusek et al, 2005;Chen, 2012;Noel et al 2013). The last was confirmed by our results since the highest Hg concentrations were recorded in fish species from the highest trophic level (European eel and perch).…”

Concentrations of eleven trace elements (Zn, M n, Cu, Fe, Cr, Ni, Co, Hg, Pb, Cd and As) as well as the principal components of fish flesh (water%, dry matter%, fat%, protein%, ash% and Ca and M g concentration) were determined in muscles of six fish species (Scardinus knezevici, Alburnus scoranza, Cyprinus carpio, Rutilus prespensis, Anguilla anguilla and Perca fluviatilis) collected from Skadar Lake in 2016. This study, being the first of its kind in fish from M ontenegrin lakes, gave the following overall ranking of the investigated elements in fish muscle: Zn > Fe > M n > Cu > Hg > Cr > As > Ni > Pb > Cd. Several significant inter-metal correlations were observed, while significant relationships between metal concentrations and fish age and size were established predominantly for essential elements. Significant inter-species differences in accumulation of analyzed trace elements were confirmed for Zn, M n, Fe and As. The total metal accumulation was the highest in roach and the lowest in perch, while European eel was found to accumulate more arsenic than other fish species. The consumption of fish from Skadar Lake doesn't pose a risk to human health.

“…Based on the comparison of the results of this study and the data published by Žlábek et al (2005), , Svobodová and Hejtmánek (1976) Svobodová et al (2004), and Dušek et al (2005), who studied various sites along the Elbe River, we may conclude that the Elbe main tributaries do not significantly affect its contamination with mercury.…”

“…The results are similar to those reported by Svobodová et al (1993) who found the mean THg concentration of 0.19 mg/kg in the chub. In the case of the Jizera, the likely source of the aquatic The results obtained in our study were compared with the study by Dušek et al (2005) who monitored mercury contamination in the Elbe between 1991 and 1996. An increased mercury concentration (0.3 mg/kg) in the Elbe was found both upstream and downstream of the Jizera discharge into the Elbe which seems to suggest that the Jizera does not play a significant role in the increased mercury contamination of the Elbe.…”

The aim of the present study was to investigate the concentrations of total mercury and methylmercury in muscle of 55 chub (Leuciscus cephalus) from seven main tributaries (Orlice, Chrudimka, Cidlina, Jizera, Vltava, Ohře, Bílina) of the Elbe River and to evaluate the health risks of eating fish from the tributaries monitored. Mercury was determined by means of cold vapour atomic absorption spectrometry using AMA-254, methylmercury in the form of CH3HgCl by gas chromatography. The highest mean concentrations of total mercury and methylmercury were found in the Jizera (0.27 ± 0.19 mg/kg and 0.23 ± 0.15 mg/kg, respectively) and the lowest mean concentrations of total mercury and methylmercury were found in the chub from the Cidlina (0.07 ± 0.05 mg/kg and 0.06 ± 0.04 mg/kg, respectively). The average methylmercury-to-total mercury ratio was 83 ± 15%. The fish intake hazard indexes calculated for the individual tributaries monitored were between 0.01 and 0.03. The results of this study show that the Elbe River is not significantly affected by mercury contamination from its main tributaries

“…ry concentrations mainly in various fish species from Bohemian rivers and reservoirs are now available (Svobodova et al, 1999(Svobodova et al, , 2004Rehulka, 2002;Spurny et al, 2002;Dusek et al, 2005;Marsalek et al, 2005) reliable mercury species data are still scarce. Sizable monitoring of mercury species in Moravian rivers hasn't been performed.…”

Contents of total mercury and mercury species (methylmercury – MeHg, inorganic mercury – Hg2+) were determined in four Moravian rivers – Jihlava, Becva, Loucka and Dyje (Czech Republic). Five tissues (muscle, gills, liver, kidney and skin) of chub (Leuciscus cephalus), zoobenthos, sediments and water samples were analyzed. Time stability of samples was also tested. The highest levels of total mercury were determined in muscle tissues of all tested fish. Relative contents of MeHg in muscle tissues of fish ranged from 83.6% to 92.0% of the total mercury contents. The relative contents of MeHg in sediments and in zoobenthos samples correlate very closely (correlation coefficient –0.83). A considerably lower content of MeHg (1.3–11.4%) was found in river sediments compared with lakes. A comparison of observed sampling sites (Vladislav, Hrubsice) proved the adverse effect of industrial contamination on the water ecosystem ofJihlavaRiver and incomplete removal of mercury species in a sewage station
