本文通过对某化工总厂的劳动卫生学调查,探讨了铅对工人健康的危害及其浓度与危害之间的关系。发现作业场所铅尘浓度最高达44.37mg/m~3。超过国家规定的卫生标准886.4倍。平均超标率为84.21％。34名工人尿铅均值为0.116mg/L,超标率为61.76％。铅中毒检出率为22.22％。铅吸收检出率为8.33％。结果表明:(1)尿铅含量与接触空气铅浓度高低有关。铅作业工令越长,铅中毒检出率越高。(2)慢性铅吸入对血压影响不明显。(3)该厂铅危害是比较严重的,在县以下工厂企业中具有一定的代表性,应引起足够的重视。
In this paper, a chemical plant labor hygiene survey to explore the health hazards of lead and its concentration and harm of the relationship between. Found that the workplace lead dust concentration up to 44.37mg / m ~ 3. More than the national health standards 886.4 times. The average rate of excessive compliance was 84.21%. 34 workers urinary lead average 0.116mg / L, exceeding the standard rate of 61.76%. Lead poisoning detection rate was 22.22%. Lead absorption rate was 8.33%. The results showed that: (1) The content of lead in urine was related to the level of lead exposure to air. The longer the lead work, the higher the lead poisoning detection rate. (2) chronic lead inhalation has no obvious effect on blood pressure. (3) The lead hazard of this factory is more serious, and it should be given enough representativeness among factories and factories below county level.
