A new approach to analysis of accumulation and enrichment of heavy metals in Danube River sediment along the Iron Gate reservoir in Serbia

Abstract

Concentrations of heavy metals (Cu, Zn, Pb, Cd) and long-lived radionuclides (U, Th, Cs) along the Iron Gate reservoir of the River Danube in Serbia were determined. In years 2005-2009, water and sediments were sampled at six sites along 200 km of the River Danube from Belgrade to Đerdap (Iron Gate) hydroelectric power plant. The concentrations of heavy metals in sediment were found to be in the intervals: 27.9-149.3 mg kg-1 for Cu, 55.2-228.4 mg kg-1 for Zn, 13.5-71.6 mg kg-1 for Pb , 0.3-25.2 mg kg-1 for Cd, and 4.0-17.5 Bq l-1 for 137Cs. These values are in correlation with concentrations in river water when expressed by the equilibrium coefficients (Kd) between solid and liquid phases. The behaviors of heavy metals were evaluated by applying models for the prediction of pollutants’ behavior in rivers. The fluxes of heavy metals from water to sediment and vice versa were also determined

Cyto‐histopathological and protein polymorphism alterations in five populations of Nile tilapia (Oreochromis niloticus) as biomonitor for water heavy metal pollution

“…Environmental pollutants, especially heavy metals, in aquatic systems represent a major worldwide problem (Milenkovic et al ., 2005; Soltan & Ata, 2018; Vukovic et al ., 2012; Vukovic et al ., 2014). Metal pollutants could be accumulated in aquatic organisms from water or via food chain.…”

Analysis of Heavy Metals Concentration in Tissues of Three Different Fish Species Included in Human Diet from Danube River

“…One of the major problems today is the presence of environmental pollutants in aquatic ecosystems, especially heavy metals. In the aquatic system, they can be deposited into sediments mainly as non-biodegradable pollutants [2][3][4]. Metal pollutants present in water can accumulate in aquatic organisms from water, sediments or through the food chain [5][6][7][8][9][10].…”

Distribution and provenance of heavy metals in sediments of the Vrbas River, Bosnia and Herzegovina

“…3 sediments, according to the toxicity of heavy metals and the response of the environment, were introduced to assess the origin of these elements. 5,7,8,[10][11][12] The aim of this paper is evaluation of the pollution level of heavy metals in the river and riverbank sediments as well as the estimation of their origin and spatial differences along the course of the Vrbas River in Banja Luka city.…”
