An Investigation on Effect of Lead Accumulation on Calcium and Inorganic Phosphate in Paint Sprayers at Nnewi South Eastern Nigeria and the Development Implications

The central aim of this research is to study the effect of lead on total calcium, inorganic Phosphate in paint sprayers exposed to lead and the control in Nnewi, Anambra state of Eastern, Nigeria, and relating the exposure to health effects. About 10 ml blood was collected from each subject. Five milliliters of this were dispensed into trace metal free tubes containing EDTA for lead analysis. The rest were dispensed into plain vacutainer tubes for calcium and inorganic phosphate analysis. Lead was determined by the method of Hessel using atomic absorption spectrophotometry (AAS). Calcium was determined by method of Ray, 1967. Inorganic Phosphorus was determined by the method of Osmond, 1887. Data were analyzed using Student t-test and ANOVA. The result shows that there was a significance difference in the blood lead, calcium and insignificance difference in the inorganic phosphate lead (30.34±0.06), calcium (7.75±0.08) and inorganic phosphate (1.01± 0.22)when compared with controls, lead (10.68±0.04) calcium (8.32±0.07) and inorganic phosphate (1.29±0.34). It is concluded that Lead effect on the paint sprayers. It is recommended that paint sprayers should be routinely checked for their blood lead level. They should remove their work clothes before entering their homes and eat a balance diet-you are more likely to absorb lead if you have a diet that is high in fat or low milk, iron, zinc or calcium.
