6/9/2017, · Heavy metal contamination in Nigeria soils is well documented. However, there is dearth of information on the intake of toxic heavy metals by some food crops cultivated in Nigeria soil. Accumulation of toxic heavy metals in edible food crops is a potential threat to human and animal health. Hence, a study on soil to food crop relation in terms of heavy metals accumulation is expedient.
