摘要
目的 :探讨铅中毒诊断标准及铅卫生标准对铅接触者健康保护效果。方法 :测定某铅冶炼厂 15 8名铅接触工人的血铅(Pb B)、尿铅 (Pb U)、锌卟啉 (ZPP)、游离原卟啉 (FEP)、δ-氨基乙酰丙酸 (δ- AL A)含量及车间空气中铅浓度并计算血铅等五项指标超过诊断值的超标率。结果 :工人在超过国家卫生标准 (铅烟 :0 .0 3 mg/ m3) 72 6倍、180倍及 11倍的环境中工作 ,其各项指标的超标率 :72 6倍的为 2 9.6%～ 5 7.4 % ,180倍的为 10 .0 %～ 4 8.0 % ,11倍的为 0～ 3 .7%。结论 :现行铅中毒诊断标准及铅卫生标准是安全的 。
Objective:To study the protecting significace of both national diagnosis standard for lead poisoning and hygienic standard for lead in workshop's air Methods: The levels of lead in blood (PbB), in urine(PbU), zinc proporhyrin (ZPP), free exythrocyte protoporhyrin(FEP),δ amino y levulinic acid(δ ALA) of 158 employees exposed to lead were determined The concentraion of lead in workshop's air was sampled According to the Standard for Lead Poisoning Diagnosis(GB 11504 89) and the Hygienic Standard for Lead in Workshop's Air, the rates of exceeding standards of the above indicates were evaluated Results: The employees working in the occupational environment with the concentration of lead in workshop's air exceed the National Hygiene standard(0 03 mg/m 3) 726, 180 and 11 times nigher rates, respectively And the rates of the biologic indexes exceed the national diagnosis standard in these three groups of workers are 29 6% ～57 4% , 10 0%～48 0%, 0～3 7%, respectively Conclusion:Both the Standard for Lead Poisoning Diagnosis and National Hygienic Standard for Lead in Workshop's Air are safe and effective for protection of worker's health
