In this study, the concentrations of Lead (Pb), Cadmium (Cd) and Chromium (Cr) in selected vegetables (tomato and cabbage) were determined in ten (10) different irrigated farmlands in Jos metropolis, Plateau State, Nigeria using Atomic Absorption Spectrophotometry (AAS). In order to establish the level of contamination and bioaccumulation in the vegetables, the soil samples from the same irrigated farmlands were also analyzed for the heavy metals. Unlike Cd which was found to be below the detection limit, about 0.388±0.171 mg/kg, 0.959±0.130 mg/kg, and 1.315±0.067 mg/kg concentrations of Pb were determined in the cabbage, tomato and the soil respectively. These values were found to be above the permissible limits (PL) of 0.300 mg/kg recommended by WHO/FAO for vegetables and below PL set for soil which is 10 – 50 mg/kg. From the result obtained it will suffice to say that the consumption of these vegetables cultivated in the farmlands irrigated with wastewater could increase the likelihood of Pb related toxicity.
