    Assessment of Rainwater Quality in Warri and Environ, Southern Nigeria for Domestic Purposes
    (Journal of Geoscience and Environment Protection,12, 2024-06-28) Agbozu,I.E, Maminor,T.R and Bassey,U (2024)
    The study aimed to assess the physiochemical characteristics of rainwater in Warri and its environment was investigated. Pb, Zn, Cd, Cu, and Cr concentrations in rainwater from the roof and non-roof sources were determined using Atomic Absorption Spectrophotometry. Three geospatial locations comprising Jakpa, Udu, and Ubeji were selected based on prevailing anthropogenic activities. The rainwater samples were systematically collected from the (aluminum) roof and non-roof sources for the months of April, June, August, and October 2022, treated and analyzed in the laboratory for sixteen physicochemical parameters. Results were statistically analyzed using ANOVA, and T-test for the determination of the level of relationships and variations across geospatial locations. Significant correlations (r = 0.72) exist between Cr in rainwater from the roof and non-roof sources. Implying point-source contaminations and may be emanating from the influence of roof materials. Furthermore, high concentrations of Cd and Pb in roof source above WHO standards were mostly in Jakpa and Ubeji. The calculated Health Risk Index (HRI) for children and adults is greater than 1. The results showed that most samples from the locations are considered not safe (HRI > 1) especially for Cd, which means that there are potential health risks in consuming rainwater from Jakpa, Udu and Ubeji. Therefore, there is a need for a prompt sensitization program to dissuade people from directly drinking rainwater from these locations.

    Traditional beliefs and conservation of natural resources: Evidences from selected communities in Delta State, Nigeria
    (Academic Journals, 2013-07) AGBOZU, I.E; RIM-RUKEH, A; IRERHIEVWIE, G
    The role of traditional beliefs systems in the conservation of natural resources in some selected communities in Delta State, Nigeria, have been studied. Methodology of study involves the use of personal interview, literature review, group discussion, and site visitation carried out by the authors between April 2011 and March 2012. Findings show that traditional natural resources management in the selected communities are classified into the following categories: protection of particular ecosystems or habitats (such as sacred groves and sacred rivers/pond); and protection of particular animals or plant species (such as totem and tabooed species). The practices concerned relate to trees, forests, wildlife and marine organisms. The environmental wisdom and ethics expressed through these religious beliefs are very useful tools in natural resource management. Using the classification of the International Union of Conservation of Nature (IUCN), the plants and animals species in the study scared groves and forest can be described as an environment with widespread and abundant taxonomy and are not at risk or endangered.
