“…S1 ) and their further decrease suggest that the anthropogenic factors have no profound effect on the accumulation of the major ions in the sediment pore water from the locations under study. At the same time, the Bratsk reservoir is characterized by a period with the maximum anthropogenic impact (1970–1998) and a period with a gradual decrease in the anthropogenic influence (from 1998 to present) 34 , 35 . These periods are related to the operation, gradual reduction and a subsequent deserting of the Usoliekhimprom enterprise, the largest enterprise of the Usolie-Sibirskoe industrial zone, which used to produce calcium carbide, caustic soda, calcium hypochlorite, sodium metal, etc.…”

This study aimed to identify the factors responsible for the major ion composition of pore water from the bottom sediments of the Bratsk water reservoir, which is part of the largest freshwater Baikal-Angara water system. In the Bratsk reservoir, the overlying water was characterized as HCO3–Ca–Mg type with the mineralization ranging between 101.2 and 127.7 mg L−1 and pore water was characterized as HCO3–SO4–Ca, SO4–Cl–Ca–Mg and mixed water types, which had mineralization varying from 165.9 to 4608.1 mg L−1. The ionic composition of pore waters varied both along the sediment depth profile and across the water area. In pore water, the difference between the highest and lowest values was remarkably large: 5.1 times for K+, 13 times for Mg2+, 16 times for HCO3−, 20 times for Ca2+, 23 times for Na+, 80 times for SO42−, 105 times for Cl−. Such variability at different sites of the reservoir was due to the interrelation between major ion concentrations in the pore water and environmental parameters. The major factor responsible for pore water chemistry was the dissolution of sediment-forming material coming from various geochemical provinces. In the south part of the reservoir, Cl−, Na+ and SO42− concentrations may significantly increase in pore water due to the effect of subaqueous flow of highly mineralized groundwater.

“…According to published data, contamination of drinking water supplies with iron (Fe) and manganese (Mn) occurs as a result of erosion of metals from the surface layer of contaminated soils (Chelyabinsk Oblast) and waste discharge from urban agglomerations (Novosibirsk Oblast, Irkutsk Oblast). The effects of industrial pollution and urbanization on environmental quality are being intensively researched to rationalize environmental management and achieve sustainable development goals (Matveeva et al, 2022;Poletaeva et al, 2021;Yakovlev et al, 2023). The elemental composition of natural environments is directly influenced by factors such as local geochemical anomalies and other characteristics inherent to the natural habitat.…”

The article presents an approach that could be adapted for other regions or serve as an illustration of local geological anomalies. The methodology included analysis of Fe and Mn content, pH, total hardness and permanganate index of 159 water samples collected from the Tyumen urban agglomeration. These parameters were compared with published data on water composition from other regions of Russia. It was found that the tap water from the Tyumen urban agglomeration has a predominantly neutral pH (5-8); the average content of organic matter (according to permanganate index) is less than 5 ppm) in all considered objects. The average water hardness does not exceed the permissible values (6 ppm); the calculated Ca2+ - Mg2+ contents are 75 and 45 mg-eq/l respectively. The average concentration of iron in water from non-centralized water supply sources and private wells within the Tyumen agglomeration is 1.9 MPC (maximum permissible concentration), while manganese levels are at 1.2 MPC. The LCIA method was used to assess the impact of Fe and Mn on freshwater ecosystems. An increased risk of non-cancerous health effects in the population utilizing well water for drinking purposes was identified, due to high concentrations of iron.

“…In recent decades, the developing countries have witnessed water pollution after unprecedented population growth and industrialization (Singh et al 2016). Thus, there remains a need for water quality assessment in inland waters by measuring the concentration of human-induced pollutants that degrade the aquatic ecosystem in any water reservoir (Hegazy et al 2020;Poletaeva et al 2021).…”

Anthropogenic activities can greatly influence the lake ecosystems across the globe. Within these ecosystems, the impacts of human activities are most evident on sedimentation, light and nutrient availability, and disturbance frequency. There have been times of natural environmental healing of reservoirs and the present research aims to explore the variations in the water quality of Tarbela reservoir, Pakistan the largest rock-filled dam of the world, from 1990 to 2020. Landsat imagery (Landsat 4-5, 5, 7 and 8) was used to monitor Land Use Land Cover (LULC), Normalized Difference Chlorophyll Index (NDCI), Normalized Difference Turbidity Index (NDTI) and Normalized Difference Water Index (NDWI) in Tarbela reservoir, and its surrounding area from 1990−2020, on decadal interval. The results indicated a significant increase in built-up area, of about 630 km2 , in the western and eastern parts of the reservoir, whereas turbidity level, revealed a substantial decline with 4% decrease observed in the last decade, 2010-2020 thus confirming improved water quality. The study also presented expanse in the spatial coverage of chlorophyll index and water index, indicating increase in residence time of the water. It is concluded that the water quality continued to deteriorate with time, however, 2020 was a year of environmental healing and there was an overall water quality improvement of the reservoir observed. The study recommends policies to be formulated for sediment flushing and turbidity reduction for longer time duration to enhance the life of this mega reservoir.
