“…Only one sample demonstrates elevated contents of Mn 472 μg/L (#S21) (Figure 5a) close to WHO limitation. But, according to European and American standards, the Mn limit for potable water is 50 μg/L [5]. Mn concentrations exceeding this value are observed at two sampling points: the Baksan River (#S4) and the Gerhondjasu River (#S12).…”

“…Heavy metals represent a global concern because of their toxicological effects on human health and the environment (e.g., [3][4][5]). Recent studies show that elevated concentrations of heavy metals in drinking water may pose a serious health threat: W can accumulate in the bones [6]; Mn affects the brain and liver and causes behavioral problems [7]; Zn increases the risk of developing neurological and behavioral disorders and delayed development [8]; Cu causes gastrointestinal upset and liver cirrhosis [8]; Pb also affects the central nervous system, renal, cardiovascular, and musculoskeletal systems [8]; Ba includes gastrointestinal issues, shortness of breath, heart damage, paralysis [9]; Mo causes digestive disorders, vascular disease, bone disease, liver and kidney changes [10]; even a low concentration of As for a long period of time damages the liver in humans and animals, not to mention the well-known cancers of the lung, liver, kidney, or bladder [8].…”

The region surrounding the Elbrus volcano in the Great Caucasus is a popular tourist destination, home to native people and an area of the richest ore mineral resources. Based on the chemical composition of surface water, mineral, and groundwater in the Elbrus area, as well as statistical and thermodynamic calculations, waters with high concentrations of Mn, Cu, Zn, Mo, Ba, W, Pb, and As were identified, possible mineral phases that may lead to these metal concentrations in water were estimated, and risks to human health were assessed. Two main sources of surface water pollution have been identified: (1) water from tailings that are enriched due to oxidation of sulfide minerals is considered a source of As (181 µg/L) and Mo (2070 µg/L) pollution in the area of the Tyrnyauz W-Mo deposit; and (2) CO2-rich waters of deep horizons discharge on the earth surface with high concentrations of As (828 µg/L) and W (504 µg/L). It has been shown that compared to all toxic elements studied, only Mo and As have adverse non-carcinogenic effects on adult health. The estimated carcinogenic risk of As in the mine area was 1.7 × 10−3 and exceeded the generally accepted range of 10−4 to 10−6. In order to minimize the health risks, regular monitoring of water quality is required when mining activities on the Tyrnyauz W-Mo deposit are renewed.

“…The parameters chosen for the classification of lake water quality used in this study are listed in Table 1. The subscripts [6][7][8] indicate the number of selected parameters for the calculation of each WQI (Table 1). The NSF 6 -WQI and CCME 6 -WQI are designed to include precisely the same parameters available in this study.…”

“…Intensive anthropogenic activities and rapid economic growth have added to the pressure on the environment and ecosystems, resulting in soil and water resource degradation, severely limiting sustainability [2][3][4][5][6]. The presence of chemical compounds is the cause of pollution in both groundwater and surface water [7][8][9][10][11][12]. These chemical substances significantly impact whether or not the water is suitable for human consumption and purposes in industry and agriculture.…”

Water quality indices (WQIs) are practical and versatile instruments for assessing, organizing, and disseminating information about the overall quality status of surface water bodies. The use of these indices may be beneficial in evaluating aquatic system water quality. The CCME (Canadian Council of Ministers of the Environment) and NSF (National Science Foundation) WQIs were used for the assessment of surface water (depth = 1 m) in Lake Union, Washington State. These WQIs were used in surface water at Lake Union, Seattle. The modified versions of the applied WQIs incorporate a varied number of the investigated parameters. The two WQIs were implemented utilizing specialized, publicly accessible software tools. A comparison of their performance is offered, along with a qualitative assessment of their appropriateness for describing the quality of a surface water body. Practical conclusions were generated and addressed based on the applicability and disadvantages of the evaluated indexes. When compared to the CCME-WQI, it is found that the NSF-WQI is a more robust index that yields a categorization stricter than CCME-WQI.

“…Trace elements in water have been highly enriched, difficult to degrade, and highly toxic, especially the excessive accumulation of toxic trace elements which not only threaten safety of invertebrates and fish ecosystems, but also cause serious health effects on human beings [1][2][3][4]. Some trace elements are extremely toxic even at low concentrations, such as arsenic (As) and lead (Pb) [5].…”

Evaluation of trace elements in the water of Lancang River during the wet season (October) and dry season (December) was carried out to analyze the content of trace elements in the water, spatial and seasonal variations, enrichment, and health risks of dissolved trace metal. The results showed that the content of trace elements in the main stream of the upper Lancang River met the “Environmental Quality Standard for Surface Water” (GB3838-2002) Class I water-quality standard, but the Fe content in sampling points during the wet season exceeded the limit value of water-quality standard. Compared with other rivers in Tibet, the contents of As, Fe, and Pb in the study were relatively high. While Pb, As, and Zn were the mainly enriched trace elements. The water temperature, dissolved oxygen, conductivity, As, Cr, and Cu in the main stream of the upper Lancang River with significant seasonal variations. The content of trace elements in the front of the dam was lower than that in the tail and under the dam. The trace elements in the water of the reservoir area increased with an increase in the depth, and the reservoir had a certain interception effect on the trace elements. The As content in the main stream of the Lancang River was greatly affected by the branch of Angqu with high content of As. The HQingestion and HI of As in the part of the river in the study exceeded 1, and the water-quality health risks of the Guoduo reservoir tail and urban reaches were higher than those of other reaches, which should be paid more attention.
