尿铅和血铅在一定程度上可反映生产作业工人体内接触铅的情况,但在劳动卫生监测实践工作中,许多基层单位只开展尿铅单项检测来确定生产作业工人的铅接触水平,造成误诊者并不少见。为了解铅作业工人尿铅和血铅含量的动态关系,我们于92年3月至93年5月对我市铅作业工人进行尿铅和血铅双项同时测定对比观察,结果报告如下。
To some extent, urine lead and blood lead can reflect the exposure of production workers to lead. However, in the practice of labor hygiene monitoring, many grassroots units only conduct single tests of urine lead to determine lead exposure of production workers and cause misdiagnosis Not uncommon. In order to understand the dynamic relationship between lead and blood lead levels in lead workers, we conducted the simultaneous determination of lead and lead levels in our city from March 1992 to May 1993. The results are reported as follows.
