Warwade water Reservoir and Oreochromis niloticus’s tissues (gills and liver) were evaluated by analyzing heavy metals concentrations and their effects on the oxidative stress enzyme from January to August 2022. Both field and laboratory assessments were conducted following established scientific protocols. Monthly sampling occurred between 6:00 – 7:00 am. Four stations denoted as A, B, C, and D, were chosen based on the diversity of anthropogenic activities surrounding the reservoir. The findings showed that heavy metals concentrations in the water ranked as follows: Chromium at 1.96mg/L, followed by Lead (1.74mg/L), Nickel (1.36mg/L), and Cadmium (1.03mg/L). Heavy metals values in fish tissues exhibited a significant decrease (p<0.05) in the following order for gill tissues (Pb > Cr > Ni > Cd) and liver (Pb > Cr > Cd > Ni). The recorded vlaues exceeded the recommended limits set by WHO (2021). Enzyme activities serving as oxidative stress biomarkers demonstrated a significant reduction (P<0.05) for Superoxide dismutase (SOD), Catalase (CAT) and Glutathione Transferase (GST), with higher mean activity observed in the gills with SOD (16.57 ±0.43), CAT (23.61±2.11) and GST (84.40±1.03) compared to liver samples of GST (81.10±0.51), SOD (14.32 ±1.08) and CAT (20.51±0.17) respectively. It may be inferred that the presence of metals in Oreochromis niloticus is a consequence of the discharge of pollutants into the water body, attributable to urbanization and the discharge of agrochemicals, which adversely impacted the water quality. Consequently, it is imperative to regulate uncontrolled discharges from human activities within the reservoir to mitigate the long-term degradation...

The water in the Jakara River consists of effluent from Bompai industries, domestic sewage from most parts of Kano city and runoffs from various local scraps and chemical processing. The wastewater in the river is the main and most preferred source of irrigation water for the farmers along the Jakara River. The wastewater in the river is rich in both organic and chemical contaminants that can contaminate soil and thriving crops. The research was designed to understand the perception of farmers about the safety of the irrigation water they use and its resulting consequences on soil quality and food safety. The information on the farmer’s awareness were gathered through oral interviews, 60 farmers were selected for data collection. Information collected includes the demography of the farmers, their farming experience, their concern about the safety of wastewater irrigation and awareness of the dangers associated with soil and food heavy metals (HMs) contamination. The majority (95 %) of the farmers ignorantly believe that the wastewater in the Jakara River is safe for irrigation and 90.00 % believe that crops cannot be contaminated when irrigated with contaminated wastewater. Only 5 % of the farmers know HMs and more than 86 % believe that even if the water is contaminated it cannot pass contamination to soil and growing crops. The overall farmers' awareness of the safety of wastewater irrigation and soil and crop HM contamination is generally poor.
