摘要：Humanprotectionat the workplace aims atknowing andremove all thesituations thatcan occurin thework,which could lead toaccidentsand occupational diseases.This study assess the occupational exposureto lead and dust forworkers from differentworkplaces in a companyproducingcar batteries.Workplace lead(Pb)concentration (39 measurements) wasperformed byX-rayfluorescencespectrometry.Biomarkers of exposure and effects have been performed for 278workers, represented byblood lead level(GF-AAS)urinary delta-amino levulinic acid(¦¤ALA)(standard regular method).The results ofworkplace air measurementspointed outhigh lead concentrations in some working areas,while the mean concentration oftotaldustdid not exceedthe maximum allowable concentration. The blood lead level (BPb)variedbetween 5.84ug dL-1and 65ug dL-1, with an averageof 33.7ug dL-1(below workplace acceptable limit ¨C40 ug dL-1. Urinary ¦¤ALAranged from 1.83mgL-1to 50.32mgL-1withan averagevalue of 8.7mgL-1.The results of thisstudyshowed thatfor about2/3oftheinvestigated workers, the occupational exposure toinorganic leadand total dust,in car batteryindustry, iswithin normal biologicaltolerablelimitforlead.
