Health risk of some metals in maize grains cultivated close to Gosa and Gwagwalada solid waste dumpsites

Maize is a vital nutritional cereal for the infants, young children and adults. The environment which they are cultivated in Africa could expose to metal accumulations from soils, thereby posing health risks consumers. objectives of this study were determine maize grains (Zea mays L.) close Gosa Gwagwalada solid waste dumpsites their via consumption. A total 36 soil samples (12 each dumpsite soil, farmland grains) collected analyzed some metals [cadmium (Cd), lead (Pb), zinc (Zn), cobalt (Co), copper (Cu), chromium (Cr), nickel (Ni) mercury (Hg)] using standard atomic adsorption spectrophotometer. transfer factors adults (60 kg; 22-48.9 years), (35 6-15 years) infants (15 1-6 evaluated mathematical models. ranges (mg/kg) detected 10114.00 0.52, 10.45 0.001 13.62 dumpsite, grains, respectively. Though, within FAO/WHO EU safe limits, Zn was significantly (p<0.05) highest both locations, while Cd, Cr Hg (0.001 mg/kg) least.

This concluded that closed poses concern thus farming around needs be discouraged safety reasons.
