- W2389739916 abstract "Objective:To study the clinical features,the law and the incidence trend of occupational lead poisoning,and to provide scientific strategy to contain tendency of the high incidence of occupational lead poisoning,the exceeding standard in vivo in 962 occupational lead exposure workers in 14 enterprises were investigated in Jiangsu province.Methods: According to the norms and standards,air samples was collected and measured the lead concentration in air,calculated the time weighted average concentration(TWA),detected the lead concentration in blood and in urine.Results: Excessive rate of lead concentration of the air were 9.76%,TWA of excessive posts were from 0.066 to 1.400mg/m3.Excessive posts were milling,powder filling,smearing,back covering,ball milling and so on.There were 255 persons'biological samples lead concentrations exceeding,out of 962 persons.The exceeding standard rate was 26.51%.With the increase of the lead-dust TWA concentration in different lead-exposure posts,the exceeding standard rates of lead concentration of biological samples were increased.The difference was significant by likelihood Chi-square test(G=97.65,P0.01).Conclusion: The situation of exceeding standard in vivo in occupational lead exposure groups was serious in Jiangsu province.With the increase of the lead-dust TWA concentration in different lead-exposure posts,the exceeding standard rates of lead concentration of biological samples were increased.A dose-response relationship was observed between TWA and the exceeding standard rates of lead concentration of biological samples.So the government,enterprises,prevention and control institutions and practitioners should take appropriate measures to mitigate the harm." @default.
