Abstract
Eight trace metals, namely cadmium, cobalt, copper, chromium, iron, manganese, nickel and lead, as well as sodium, potassium, calcium and magnesium were determined in fresh Nigerian fruit and vegetables. Soil samples were also analysed for trace metals. The results show that trace metals occurred at low concentrations, and seem to reflect background levels, although higher concentrations and wider distribution were observed in the vegetables than in fruit. Their sodium, potassium, calcium, magnesium and iron content compared well with, values reported for American fruit and vegetables.Keywords
