The aim of this study was to evaluate the concentration of heavy metals namely (Lead (Pb), Nickel (Ni), Cadmium (Cd) and Chromium (Cr)) via consumption of vegetables from selected markets in Bayelsa State, Nigeria. Sixteen different vegetable samples comprising of Bitter leaves (Vernonia amygdalina), Curry leaves (Ocimum basilicum), Scent leaves (Ocimum gratissmum), Water Leaves (Talinum triangulare), Uziza (Piper guineese), Fluted pumpkin (Telferia occidetalis), Okazi (Gnetum africanum), and Okra (Abelmoschus esculentus) were digested and analyzed for heavy metals using Solar Thermo Elemental Flame Atomic Absorption Spectrophotometer (STEF-AAS). Results obtained were used to estimate the health risk of these heavy metals via consumption of the vegetable samples. The results from the study showed that the heavy metal concentration ranged between 0.016 to 1.387 mg/kg, 0.028 to 1.487 mg.. View More»
