随着社会主义事业的发展,在工业生产中铅及其化合物的应用越来越广。接铅作业的工人日益增多,铅及其化合物是目前最常见职业中毒的毒物之一。但是典型中毒病例的发生已不多见,往往症状体征不很明显。为了保护工人健康,从“预防为主”出发,早期发现铅吸收和轻度铅中毒患者,需要我们找出更多方法。尿铅测定经过多年广泛的使用,已经证明,仍是重要的诊断指标,它与血铅浓度及所接触的空气铅浓度有密切关系。但是尿铅排泄的波动幅度较大,可靠性常受很多因素的影
With the development of the socialist cause, the application of lead and its compounds in industrial production is more and more widely used. The number of workers receiving lead work is increasing. Lead and its compounds are among the poisons most commonly poisoned by occupations. However, the incidence of typical poisoning has been rare, often not obvious signs and symptoms. In order to protect the health of workers, starting from “prevention,” early detection of lead absorption and mild lead poisoning need us to find more ways. After years of extensive use of urinary lead determination, it has been proved that it is still an important diagnostic indicator. It is closely related to blood lead concentration and air lead concentration in contact. However, urinary lead excretion greater volatility, reliability often affected by many factors
