Abstract

ABSTRACT Heavy metal contamination in food crops poses a significant health risk, making it essential to monitor their concentrations in agricultural produce. This study investigates the levels of arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), and mercury (Hg) in sweet potato samples cultivated in Jalingo, Yorro, and Zing Local Government Areas (LGAs) of Taraba State, Nigeria. The results indicate that all detected heavy metal concentrations were within the permissible limits set by the World Health Organization (WHO). Jalingo samples showed no detectable levels of As, Cd, and Hg, with Cr and Pb present at minimal levels. Yorro samples contained trace amounts of Cd, Cr, and Hg, while As and Pb were undetected. Zing samples had As, Cd, and Hg in minimal concentrations, with Cr and Pb undetected. The findings suggest that sweet potatoes from these areas are safe for consumption, though continuous environmental monitoring is recommended to prevent future contamination.
