Heavy metals health risk assessment for population via consumption of food crops and fruits in Owerri, South Eastern, Nigeria
<p>Abstract</p> <p>Background</p> <p>This study assessed lead, cadmium, and nickel level in food crops, fruits and soil samples from Ohaji and Umuagwo and Owerri in South Eastern Nigeria and estimated the potential health risks of metals. Samples were washed, oven-dried...
