  • Abstract

    Consumption of vegetables contaminated with heavy metals can cause serious health ‎problems, including kidney damage, cancer, high blood pressure, and impaired brain ‎development. This study analyzed levels of Zn, Fe, Mn, Cd, Cr, and Pb in 10 vegetables from ‎the Kura-Dakasoye agricultural area in Kano State using Atomic Absorption ‎Spectrophotometry after wet digestion. Metal concentrations were generally within safe limits, ‎except for lead. ANOVA showed no significant differences among the vegetables (P > 0.05). ‎Estimated Daily Intakes (EDIs) for all the analyzed metals were found to be below their ‎respective oral reference doses, and Hazard Quotients (HQs) were all less than one, indicating ‎no significant non-carcinogenic health risk. The findings suggest minimal health risk to ‎consumers, aside from possible lead exposure‎.
