Abstract
Abstract This paper aimed to assess the water quality and estimate the percentages of potentially toxic elements that would be removed to make water resources in Ojoto and its environs (Nigeria) safe for drinking. Standard procedures were followed in physicochemical analyses. Novel integrated-weight water quality index revealed that only 4 out of 28 water stations were suitable. Heavy metal toxicity load estimated that 92%, 48%, 89%, 79% and 98% of Fe, Zn, Ni, Cr and Pb, respectively, are required to be removed from the waters to reduce pollution. Hierarchical agglomerative clustering showed the spatiotemporal water quality classes in the study area.
期刊介绍：
Toxin Reviews provides an international forum for publishing state-of-the-art reviews and guest-edited single topic special issues covering the multidisciplinary research in the area of toxins derived from animals, plants and microorganisms. Our aim is to publish reviews that are of broad interest and importance to the toxinology as well as other life science communities. Toxin Reviews aims to encourage scientists to highlight the contribution of toxins as research tools in deciphering molecular and cellular mechanisms, and as prototypes of therapeutic agents. Reviews should emphasize the role of toxins in enhancing our fundamental understanding of life sciences, protein chemistry, structural biology, pharmacology, clinical toxinology and evolution. Prominence will be given to reviews that propose new ideas or approaches and further the knowledge of toxinology.
