“…Lake sediments are subject to material accumulation in watersheds and reflect the source-sink process [1]; lake sediments are also an important part of the lake environment and have special importance for ecological processes [2,3]. Lake sediments possess a high holding capacity for various pollutants.…”

Aiming at the pollution and ecological hazards of the lake sediments of Bosten Lake, once China’s largest inland lake, the spatial distribution and influencing factors of the potentially-toxic elements in its surface sediments were studied with the methods of spatial autocorrelation, two-way cluster analysis, and redundancy analysis. Finally, based on the background value of potentially-toxic elements extracted from a sediment core, a comprehensive evaluation of the risk of these potentially-toxic elements was conducted with the potential-ecological-risk index and the pollution-load index. With data on the grain size, bulk-rock composition, and organic matter content, this comprehensive analysis suggested that with the enrichment of authigenic carbonate minerals, the content of potentially-toxic elements exhibited distinctive characteristics representative of arid regions with lower values than those in humid region. All potentially-toxic elements revealed a significant spatial autocorrelation, and high-value areas mainly occurred in the middle and southwest. The content of potentially-toxic elements is related to Al2O3, K2O, Fe2O3, TiO2, MgO, and MnO, and the storage medium of potentially-toxic elements mainly consists of small particles with a grain size <16 μm. The pollution load index (PLI) for the whole lake due to the potentially-toxic elements was 1.31, and the surface area with a PLI higher than 1 and a moderate pollution level accounted for 87.2% of the total lake area. The research conclusions have an important scientific value for future lake ecological quality assessment and lake environment governance.

“…In the springs of the districts of Andahuaylas, San Jerónimo, and Talavera, the pH levels are within the limits established by the WHO [14] The study area with an altitude higher than 3500 m is largely covered by ichu (Stipa ichu) and a few native plants, such as puna muña. These plants supply dissolved organic compounds, for instance humic substances [26], which directly influence water color, and values of 0.0 TCU are reported due to the low floral density of the study areas. On the other hand, the color of the water is also influenced by the presence of metals, such as iron, and the geology of the areas of the study show high levels of rocks with iron content [10,27,28].…”

The headwaters of the high Andean basin in Peru accumulate water from the mist, rain, snow, and hail, and it is transported superficially and underground to low-lying areas, mostly used for drinkable purposes. The natural water in these areas might be altered due to legal and illegal mining extraction. The aim of the study was to evaluate the water quality for human consumption. Seventeen water samples were examined from Andahuaylas (A), San Jerónimo (S), Talavera (T), and Chiara (CH) districts located between 2813 and 4004 m altitude in the Andes. We used physicochemical, microbiological, and metal parameters, and the results were compared to permissible levels established by the WHO and ECA-Peru to examine samples collected in the dry and rainy seasons in 2019. Application of principal component analysis (PCA) identified areas and conditioning parameters. Extractive mining activity influences the quality of springs due to the presence of metals, especially antimony (Sb), arsenic (As), cadmium (Cd), and lead (Pb), values of which are higher than values permissible for human consumption, being higher in the dry season (p < 0.05). In addition, the presence of cations and particulate matter affects physico-chemical parameters, for example turbidity. PCA showed that parameters for water characterization are season-independent, and water quality in the springs would be conditioned by the presence of metals, especially in Andahuaylas and Talavera zones, as well as the parameters that are associated with dissolved solids in the water (turbidity and fluorides). A frequent monitoring program of springs and groundwater is recommended, with the purpose to protect water from contamination and guarantee safe water availability in low-lying and urbanized areas.

“…The metal contamination of the water samples was evaluated using metal index (MI), contamination factor (Cf) and degree of contamination (Cd). These describe the limits and extent of pollution of water by metals (Rahman et al 2020;De Anda et al 2019;Mukanyandwi et al 2019;Pandey et al 2019;Shen et al 2019).…”

“…Iron and manganese exhibits similar chemistry and this makes them bioavailable in aquatic biota. Their presence in water increases water acidity(De Anda et al 2019). Zinc had its highest (1.13 mg/L) values recorded in N1 in rainy season and 1.00 mg/L in dry season in S1 and W2.…”

The study conducted in dry and rainy seasons in 2019 assessed the levels of metals in ground water sampled from boreholes and dug wells in Ikwo, south-eastern Nigeria. Nine water samples were analysed for calcium, iron, zinc, copper, manganese, and aluminium using Atomic Absorption Spectrophotometer (AAS). Analysis showed higher metal concentrations in rainy season, except for manganese whose concentration was higher in the dry season. The levels of the metals exceeded permissible limits in both seasons except for calcium. The metal indices were not greater than 2 while all degrees of contamination were less than 1. This collaborative classification of both metal index and degrees of contamination suggest that water samples were safe for human consumption. The health risk evaluated by hazard indices (HI) were categorized into low and medium (≥ 0.1 to < 4) levels of chronic risks. The HI values, evaluated for both children and adults; were predominantly medium for children and low for adults. All indices for water quality evaluation revealed that ground water in the study area is of minimal contamination hence, no immediate threat to health. Therefore, to ensure quality water supply, sustainable monitoring of water quality is recommended in the study area, with continuous environmentally friendly agricultural practices.
