Abstract

Aims: To assess the source and level of Nickel in selected surface waters and its impact on the community of the Bonaberi industrial zone. Study Design: Cross-sectional study design that involved semi-quantitative and qualitative data collection method. Place and Duration of Study: This study was carried out in the area of Bonaberi industrial zone, Douala IV district between February 2019 to August 2020. Methodology: 25 Different surface water samples were collected from 5 sampling sites. Water samples were collected in polyethylene bottles previously washed with deionized water and rinsed with sample to be collected from different sites and acidified with 5 ml concentrated nitric acid. The contents of the metal were analyzed using Colorimetric merck microquant procedure. Two way ANOVA test and a P-value (<0.05) was considered significant. Results: Spring Water had a significant concentration of nickel in the various sites (0.06 mg/L), industrial waste (0.05 mg/L), River (0.04 mg/L), Well (0.03 mg/L), Tap waters (0.02 mg/L). Conclusion: Nickel is one of the most toxic naturally occurring metal(s) that is very dangerous to environmental sustainability when present in high concentrations. The study justifies the need to ascertain the long-term effects of Nickel contaminant(s) at waste dumping sites. Strengthening waste management systems and water quality monitoring should be implemented in the watersheds to minimize the health effects and deterioration of the aquatic ecosystem. Adequate measures should be taken to educate the community on heavy metals pollution on surface water and their effects to health and environment.
