- Abstract
The role of Livestock in the production of safe food has underlined its impacts on public health and food security. Samples of grasses Carpet Grass (Axonopus lompressus), Guinea Grass (Panicum maximum) and Elephant grass (Pennisetum purpureum) used as fodder grown on the vicinity of iron mine of Itakpe, Nigeria were analyzed for Cd, Cu, Mg, Ni, Pb and Zn. Samples from Ossara 12 kilometers away from Itakpe was used for comparison. All elements were determined by AAS. Mean concentration of total metal content of agricultural soils investigated gave 0.16 ±0.02, 0.15±0.03, 0.04±0.03, 0.1±0.02, 0.07±0.01 and Zn 0.04±0.04 mg/g for Cd, Cu, Mg, Ni, Pb and Zn respectively. High levels of metals were found in the tailings (Mn 700, Pb 200, Cd 23, Ni 41, Fe 244,000 mg/g). Total concentrations of the elements in grasses were 0.02±0.01, 0.06±0.01, 0.11±0.02, 0.06±0.04, 0.03±0.01, 0.07±0.01 mg/g for Cd, Cu, Mg, Ni, Pb and Zn respectively. Total concentrations of the elements examined were within ranges normally encountered in soils and the observed metallic levels of the grasses were below the FAO/WHO limit guideline values for heavy metal levels in food.
