Pollution and Ecological Risk Assessment of Potentially Toxic Elements in Natural Waters from the Ameka Metallogenic District in Southeastern Nigeria

Analytical Letters, Journal Year: 2020, Volume and Issue: 53(17), P. 2812 - 2839

In mining areas, several potentially toxic elements (PTEs) are often released in excess quantities into the ecosystem; thereby, predisposing both human beings and environment to pollution risks. The current paper investigated status ecological risks of PTEs groundwater resources from Ameka its environs, southeast Nigeria, using numerical chemometric models. Both hand-dug wells borehole samples were analyzed. order abundance waters was Co > Se Cd Ni Mn Fe Zn As Pb Cu, for samples. Environmental risk assessment models such as contamination factor, degree, index, load Nemerow integrated modified heavy metal index showed that 100% highly laden with PTEs. Similarly, pose very high Furthermore, water quality jointly revealed all analyzed sources this area unsuitable consumption. Chemometric tools factor analysis hierarchical cluster used establish inter-parameter relationships. It realized geogenic anthropogenic factors responsible enrichment natural waters. Therefore, based on overall findings study, adequate treatment polluted before drinking is recommended.

Pollution assessment and estimation of the percentages of toxic elements to be removed to make polluted drinking water safe: a case from Nigeria

Toxin Reviews, Journal Year: 2022, Volume and Issue: 42(1), P. 146 - 160

This paper aimed to assess the water quality and estimate percentages of potentially toxic elements that would be removed make resources in Ojoto its environs (Nigeria) safe for drinking. Standard procedures were followed physicochemical analyses. Novel integrated-weight index revealed only 4 out 28 stations suitable. Heavy metal toxicity load estimated 92%, 48%, 89%, 79% 98% Fe, Zn, Ni, Cr Pb, respectively, are required from waters reduce pollution. Hierarchical agglomerative clustering showed spatiotemporal classes study area.
