Abstract

This study was conducted to determine concentration levels of heavy metals and element in irrigated leafy vegetables and fruit cultivated at colleges’ farm along river Kumodu Gana bank, Maiduguri. Samples were obtained randomly from five locations and analysed as described by AOAC, (1990). Cadmium, copper, iron, potassium, manganese, nickel, lead and zinc were determined in plant parts of spinach (Amaranthus blitum), jute wallow (Corchurus tridents), roselle (Habiscus sabdariffa variety), and fruits of pepper (Capsicum species). The results revealed mean concentration level of each element determined in the vegetable plants studied; for cadmium had 0.80 - 3.21 µg/g, copper (0.38 - 1.58 µg/g), iron (0.27 - 1.89 µg/g), potassium (6.6 - 27.13 µg/g), manganese (0.26 - 2.42 µg/g), nickel (0.23 - 4.21 µg/g), lead (0.32 µg/g), and 0.13 - 0.74 µg/g for zinc. The magnitude of concentration levels of these elements detected in different irrigated vegetable plant parts materials’ sequential order was K > Ni > Cd > Mn > Fe > Cu > Zn > Pb, the highest was potassium (K), the least was lead (Pb) and Pb was detected in roselle (Habiscus sabdariffa variety) only. No significance differences between the plant parts when compared their concentration levels in term of the elements determined. Their concentrations are below the recommended safe limit proposed by AOAC, EU, FAO and WHO. Hence, irrigated vegetables cultivated in the studied area were found fit, wholesome for consumption and health risk free. Further studies on the same irrigated vegetables and area are recommended.
