Abstract
Lead ion concentration in blood samples of the hospitalized patients of the mineralized area of Ishiagu environs, were assayed. Ishiagu has lead and zinc deposits and active mining of these minerals. Lead concentration in the blood of selected hospital patients range between 0.40 and 2.00 ppm. The lead (Pb) concentration varied with age. Residents within the age of 5-20 years have lead concentration of 0.40-1.00 ppm while age within 21-60 years have lead concentration of 1.00-2.00 ppm. A correlation between length of exposure and age was established. A group within 33-44 years has the highest lead concentration in their blood.
