许多工业医师都曾遇到过铅作业工血铅值低于过去的阔值—80微克/100毫升,却表现出有不相称的毒性症状,为此,本文着重讨论可能形成急性毒性危险的血铅水平的“安全”界限。作者对一个正常对照组和三个接触铅组的工人进行研究,每组5人。三个接触组为同一纯铅冶炼厂的工人,其中,一组是无毒性者,血铅水平为50～75微克/100毫升,一组是高血铅有毒性者,其血 Many industrial physicians have encountered lead work in which blood lead levels are below the previous threshold of -80 micrograms / 100 milliliters, but exhibit disproportionate toxicological symptoms. To this end, this article focuses on the possible formation of blood that is at risk for acute toxicity Lead levels of “safety” boundaries. The authors conducted a study of one normal control and three workers exposed to lead, five in each group. The three contact groups were workers from the same pure lead smelter. One group was non-toxic with a blood lead level of 50-75 μg / 100 ml. One group was those with high blood lead toxicity and their blood
