The Effectiveness of Vitamin D , Succimer and Safety Precaution Measures in Regulation of Elevated Blood Lead in Fuel Station Workers.

Abstract

Background: Continuous exposure to air polluted with the vapor of lead (in leaded gasoline) by the workers in petroleum stations without following safety measures, results into elevated level of inorganic lead in blood of those workers and put them at increased risk of toxicity through exposure to lead and its products. The aim of the present study is to measure concentration of lead in blood of fuel station workers. Subject and methods: Lead in blood was measured through lead care of blood testing system and lead care of blood testing kits, and confirmed by using Atomic Absorption Spectrophotometry(AAS) for confirmation and checking quality of measuring and repeat measuring of lead concentration in blood of workers with blood lead conc.> 50 μg/dl. This study took two approaches: a case-control approach in which 76 Petroleum station workers and age-matched control participants were included, and an experimental approach in which the effect of various types of lead decreasing agents was investigated after
