WEBFeb 9, 2022 · Stable isotopes of nitrate (δ15 N-NO 3) in the Danube River varied from lower values (+ 6.7 ‰) in the Upper Danube to higher values after the mixing with Morava River (+ 10.5 ‰) and showed...
Danube river water quality trends: A qualitative review based …
WEBOct 1, 2021 · In 2011, Serbia's Danube River water, monitored at 17 sampling sites, could be best described as moderately polluted (Voza et al. 2015). 11 WQ parameters were analyzed: water temperature, pH value, suspended solids, dissolved oxygen, ammonium, nitrate, orthophosphate, silicate, sulphate, chloride, and …
Estimation of per- and poly-fluoroalkyl substances mass loads in …
WEBSep 20, 2023 · This study of 14 major European rivers investigated water concentrations and estimated annual mass loads for four perfluoroalkyl carboxylic acids (PFCAs) across Europe. Total emissions were estimated at 18.22 t year−1; and the Danube was typically the second or third largest mass load contributor for each PFAS studied.
WEBTraditional abundance data and relative abundances in ferred from eDNA sequence reads were not similar, but both produced plausible longitudinal successions of fish communities along the Danube River.
Restored floodplains could remove 38 000 tons of nitrate pollution …
WEBJan 25, 2023 · The Danube river basin, flowing through 10 countries in central and eastern Europe, has long been affected by elevated nitrate (NO 3) levels, from agricultural run-off and other sources, causing eutrophication.
Mobility and natural attenuation of metals and arsenic in acidic …
WEBJun 22, 2018 · Bor, Krivelj, and Bela Rivers belong to the watershed of Timok River, which is a tributary of transboundary Danube River. These rivers receive metal-rich acidic wastewater from metallurgical facilities and acid mine drainage (AMD) from mine wastes around Bor copper mines.
WEBWe applied stable isotopes of water and nitrate together with contaminants of emerging concern (CECs: carbamazepine, cafeine, sulfamethoxazole, perfluorooctanoic acid and 2,4-dinitrophenol) to ...
Suspended Sediment Metal and Metalloid Composition in the Danube River …
WEBOct 11, 2022 · The purpose of this investigation was to calculate the daily values of chemical elements in the transmission of suspended sediment and its accumulation in the suspended matter collected at some hydrological stations in the Danube River Basin during high flow events.
Nitrate sources and mixing in the Danube watershed: implications …
WEBFeb 9, 2022 · The Danube River Basin (DRB) has been affected by elevated nitrate concentrations and a massive loss of intact floodplains and the ecosystem services they provide.
Hydrochemistry and isotope geochemistry of the upper Danube River
WEBNov 1, 2002 · The upper Danube, because of its considerable lateral homogeneity and essential absence of direct local groundwater influx, represents an example of a river that is suitable for the study of origin and processing of dissolved constituents in river water.
