“…Also, the study by Bennett et al (2021) found that 59% of the inventoried usable groundwater points are used to provide drinking water to the local community despite their high F⁻ values, which exceed both WHO and Tanzanian limits, as most local people do not have any alternative for drinking water. Other than high F⁻ values, the study by Tomašek et al (2022) found elevated levels of multiple potentially toxic elements (i.e., Molybdenum and Uranium) in some of the analysed sources, pose another health concern to the local communities. Therefore, the present research investigates the localities of low F⁻ groundwaters using conceptual groundwater flow model and hydrogeochemical analysis approach on the eastern, northern, western and south-western flanks of Mount Meru based on the results of Bennett et al (2021), in order to identify and locate the groundwater sources that can be used for drinking water supply without health impacts on the population.…”

This study investigated the occurrence and distribution of rare earth elements (REEs), including 14 lanthanoids, scandium (Sc), and yttrium (Y), in groundwater around a large coal-fired thermal power plant (TPP). The ICP-MS technique was used to analyze 16 REEs in groundwater samples collected from monitoring wells. REE concentrations ranged from 59.9 to 758 ng/L, with an average of 290 ng/L. The most abundant was Sc, followed by La, accounting for 54.2% and 21.4% of the total REE concentration, respectively. Geospatial analysis revealed the REE enrichment at several hotspots near the TPP. The highest REE concentrations were observed near the TPP and ash landfill, decreasing with the distance from the plant and the landfill. REE fractionation ratios and anomalies suggested the Light REE dominance, comprising over 78% of the total REEs. Correlation and principal component analyses indicated similar behavior and sources for most REEs. Health risk assessment found hazard indices (HI) of 1.36 × 10−3 and 1.98 × 10−3 for adults and children, respectively, which are far below the permissible limit (HI = 1). Likewise, incremental lifetime cancer risks (ILCR) were all below 1 × 10−6. Nevertheless, ongoing ash disposal and potential accumulation in the environment could elevate the REE exposure over time.

“…Potentially toxic elements (PTEs) are naturally occurring or anthropogenic elements that have the potential to cause adverse health effects in humans and ecological systems [ 1 , 2 ]. Examples of PTEs include arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), nickel (Ni), lead (Pb), mercury (Hg), and many others [ 3 ].…”
