The Danube Delta is a wetland of global importance, providing several ecosystem services. The sustainable development (i.e., economic, social and environmental) in the area depends on the health, quality and quantity of the natural resources. Water is one of the most important resources. Largely, the Danube Delta, which receives the input of water and sediment flux from the Danube River, gathered form its entire basin, may experiences lower water quality due to natural and anthropogenic factors, from basin to loca...

Several geochemical analyses (bulk parameters, particle size, loss on ignition, major, minor and trace elements) were performed on 51 recent sediment samples collected in May 2022 from Rosulet, Rosu and Puiu lakes which are located in the fluvio-marine delta plain of the Danube Delta, Romania. The aim of this study was to decipher the potential origin of anthropogenic and/or natural sources, weathering, sedimentary processes and the local geochemical fingerprint on the distribution of specific chemical elements in...

Water quality was investigated in Lake Matita, part of the Danube Delta Biosphere Reserve, Romania, to assess the overall status of the freshwater ecosystem, in accordance with the EU Water Framework Directive (WFD ? 2000/60/EC), which addresses all surface waters i.e., rivers, lakes, transitional waters and coastal waters in the EU. From this perspective, a specific physical and chemical analysis of surface water samples was performed, collected in different sectors of the lake, during the summer of June 2020. Se...
