On the Specifics of Formation of the Qualitative Characteristics of Waters and Sediments in the Lena River Delta [PDF]

Учёные записки Казанского университета: Серия Естественные науки, 2017
The paper considers the qualitative characteristics (chemical composition of waters and sediments, biological diversity) of the Lena runoff and their transformation as a result of the biogeochemical pro-cesses taking place in the delta region.

Analysis of water quality parameters in foothill rivers in the context of the construction of dam reservoirs

Frontiers in Environmental Science
Backwater in retention reservoirs is potentially exposed to various contaminants, such as nutrients or heavy metals. Therefore, actions performed at the construction planning stage for such a facility are crucial; they are aimed at precisely evaluating ...

Source analysis of nitrate pollution in a typical tributary of the upper Yellow River using a combined approach of stable isotopes and DOM fluorescence characteristics

River
Identifying the sources and characteristics of water pollution is essential for the protection and management of water environments. Nitrate (NO3−) is a key pollutant affecting water quality in the Qingshui River, a typical semi‐arid tributary in the ...
