Abstract

This study described and assessed heavy metals and micro elements in Amaranthusviridis sold at some major markets in Ibadan. Fresh samples of Amaranthusviridis was collected randomly from some major markets in Ibadan, Oyo State. The edible part on the plant was taken to the laboratory for heavy metal analysis to determine the level of selected micro-element namely: Manganese (Mn), Iron (Fe), Chromium (Cr), Lead (Pb) Copper (Cu), Zinc (Zn) and Nitrogen (N). The sample was washed and air dried, grinded and aid digestion was done using concentrated Hydrogen tetraoxonitrate(v) (HNO3) by Atomic Absorption Spectrometer (ASS) method. Data on metal content from ASS was presented in descriptive statistics. Result reported confirmed that the vegetable collected from major markets in Ibadan contained substantial amount of heavy metals. However, all of them are consumable which had Chromium (Cr). The best concentration in vegetable was collected from Dugbe market thereby making it the best for consumption. Therefore, vegetables collected from Dugbe market in Ibadan should be consumed more.
