Investigation On Health Status Of Occupation Workers Exposed To Lead

Objective: This research investigated occupational exposure of lead compounds in the enterprises of suzhou industrial park, to understand the impact of lead occupational exposure on the workers’ health.Methods: The workplaces of lead exposure in the suzhou industrial park were randomly selected, the lead concentration in workplace was measured and the health status of the workers exposed to lead were investigated to analyze the risk factors affecting the workers health. The survey data were double entry and the method of multiple regression was used to analyze the risk factors in order to provide information for labor protection and occupational health.Results:1, Among the 224 air samples from 7 workplaces with lead exposure,only 75 samples were less than the occupational time weighted average limit,with an average rate of 33.5%。Most of the workshop roofs were provided with vents and ventilation equipment, but 27% of them were not utilized. Personal protective equipments such as overalls, cotton masks, cotton gloves, were provided and pre-job training was carried on for the workers.2, The mean blood lead concentrations in workers was 89±23 u g/L, among them only 4% of the workers were diagnosed as mild lead intoxication. Other abnormal findings included anemia(39.8%); cereal third transaminase lifts(9.4%); self-conscious symptoms(54.8%), digestive symptoms(41.2%), and cardiovascular system abnormality(90.3%).3,The risk factors affecting the blood lead level of workers included workers’ lead exposure levels and length of service. The gender, seniority and age had little effect on blood lead concentration.Conclusion:High concentration of lead in the air of workplace is the main risk factor that affect the blood lead level of occupational workers.
