Prevention of Chronic Lead Toxicity on Adult Worker with Calcium Supplement

Lead can cause health disorders in humans, albeit at a lower level than the permitted maximum blood lead level. Therefore, a treatment should be sought that will reduce lead in the blood, especially in adults. Communities who have a high risk for chronic lead poisoning from the ambient air are employees who work on the road. This study aims to analyze the effects of calcium supplementation on blood lead levels in adult workers. This research uses quasi-experimental design with a community trial design for as many as 150 people, the group consisted of 75 control and 75 treated groups which were given calcium supplements at a dose of 500 mg 3 times daily for three months. Measurements of blood lead levels were taken before consuming calcium and three months afterwards by using Spectrofotometer at Clinical Laboratory. Subjects who completed the study on a regular basis totaled 87 people, divided into a control group of 46 people and the treated group of 41 people. The results showed that: (1) the initial blood lead levels in the control group 6.11 μg/dL and 4.16 μg/dL after treatment. Initial blood lead levels in the treated group 10.35 μg/dL and 3.2 8 μg/dL after treatment; (2) calcium treatment with a dose of 3 x 500 mg a day orally for 3 months can reduce blood lead levels significantly. This study found that calcium tablets can be used to reduce blood lead levels in adult workers.
