Study on Lead Pollution and Blood Lead Level in Lead Workers of Storage Battery Plant

Abstract

Objective To explore the situation of lead pollution and blood lead level of lead workers in storage battery plant,to explore the relations which might affect the blood lead level of workers and lead density in the air,and provide evidence for formulation of appropriate occupational health countermeasures.Methods The occupational health check was performed on 103 workers with lead exposure,and Determines the blood lead concentrations,and monitoring concentrations of lead in the air of workplace,Results The over standard rales of air lead concentration were 41.7 ％ in working places,that of blood lead were 38.8％ in lead workers,while the mean blood lead level of those lead workers was (381.81 ± 180.75) μ g/L; The differences of blood lead density between lengths of service and genders were not significance( P＞ 0.05 ) The blood lead level of lead worker was good correlation with the air lead density (r=0.9663,P＜0.05).Conclusion The lead-exposure is proved to be the obvious occupational hazard for the workers in this battery plant,and the higher lead concentrations in the air of work-place were the hazardous factor for elevated blood lead level.
