The present study is aimed at determining the heavy metal concentrations of selected vegetables in Ilesha markets, Osun state. Three samples of the vegetables were purchased from Ilesha markets in Osun State, Nigeria. The edible portion of the collected vegetable samples was properly separated, washed and chopped into small pieces using a knife. The vegetables were air-dried and then dried in an oven at 80 °C. Dried samples of the vegetables were ground into a fine powder (80 mesh) using a commercial blender. Heavy metals in vegetable samples were extracted by acid digestion and analyzed for Cadmium, Lead, Cobalt, Chromium and Nickel using a flame atomic absorption spectrophotometer. The results obtained showed that Waterleaf, African spinach and Lagos spinach had Cadmium (0.01±0.006, 0.02±0.006 and 0.005±0.006 mg/kg), Lead (0.48±0.06, 0.46±0.01 and 0.29±0.008 mg/kg), Cobalt (0.99±0.07, 0.23±0.008 and 0.87±0.006mg/kg), Chromium (0.11±0.008, 0.01±0.006 and 0.04±0.006 mg/kg) and Nickel (0.005±0.006, 0.01±0.006 and 0.01±0.006). Vegetables assessed for heavy metals are within the required regulatory standard for heavy metals permissible level. ...Preview Download Preview +Other Science Technology project topics and materials you might be interested in»Bacteriological qualities of food thickener deuterium microcarpum (ofor) and brachystegia eurcycoma (achi) sold in Owerri main market»Obstacle detection robot with ultrasonic sensor»Design and construction of cell phone charger»Physiochemical assessment of soil samples from Nwambe Reserve Forest, Ndubia Igagu Izzi L.G.A, Ebonyi State.»Antitrypanosomal activity of ethanol extract of Tridax Procumbent leaf and whole flower on T.
