Abstract
Vegetables are an
important part of all humans and animal diet due to its nutritional contents.
Their contamination with heavy metals due to soil and sources of water for
irrigation, especially during the dry season continue to poses a threat to
their quality and safety to humans and animals health. This study therefore
determined the possible health risk of consuming vegetables grown on wastewater
irrigated farms along Gombe Road and Bayara using the Atomic Absorption
Spectrophotometer. The range of concentration of Fe, Cu and Zn in the
vegetables are below the WHO/FAO permissible limits while Cd (2.84 –
4.60mg/kg), Ni (0.71–1.32mg/kg) and Pb elow their reference oral doses. The
non-carcinogenic risk (HI) values obtained for each Vegetables in the study
sites were higher than 1 while carcinogenic risk (CR) assessments indices were
greater than 1.0E-6. Both HI and CR results obtained for children were observed
to be higher than those of the adults in most cases. It is therefore suggested
that an in-depth toxicological effect analysis in the study farms be carried
out, while the consumption of these vegetables from these farms be reduced to
mitigate the adverse effects of these heavy.
