ABSTRACT. Battery production is one of the main sources of heavy metals that present great harm to human health even in low concentrations. Chromium (Cr), Cadmium (Cd) and Lead (Pb) were measured in edible portions of vegetables and soils around a battery production area in China, and the potential health risk of heavy metal contamination to the local population via vegetable consumption was ...

The EPA 2007 method may be used for multi-elemental and some non-metal analyses in solution using ICP-AES. The method is considered a consolidation of prevailing methods for water, ,wastewater,, and solid wastes (US-EPA, 1994, 1992). The revised method 3050B by US-EPA (1996) is used for ,acid, digestion of sediments, sludges, and soils.

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.
