目前国内对尿铅测定结果表示方法尚不统一。作者用四种表示方法进仃了比较。结果表明,无论哪种方法均不同程度地受到有关因素的影响,而呈现尿铅值的一定波动幅度。但以尿铅/尿肌酐比值法表示波动值不大,尚能符合肌体铅含量及排铅的生理状况,有助于铅作业人群的劳动监测及其诊断指征。测定尿铅可估算肌体真正的铅接触水平,也可反映接触—负荷—排出之间的关系。但尿铅的测定值受诸多因素影响,波动较大。除肌体差异、生活习惯及实验因素外,与测定结果的表示方法也有一定关系。鉴于国内对尿铅测定结果的表示方法尚不统一,作者在实际工作中,用四种不同的尿铅结果表示方法,进行了实际应用,取得了一定的应用经验。现报道如下: At present, the results of determination of urinary lead that the method is not uniform. The author uses four means of representation to Dingding comparison. The results show that no matter what method are affected by the factors to varying degrees, but showing a certain degree of fluctuations in urine lead. However, the urinary lead / urinary creatinine ratio method shows that the value is not large, yet able to meet the body lead content and lead physiological conditions, to help lead workers in labor monitoring and diagnostic indications. Determination of urinary lead can estimate the body’s true level of lead exposure, but also reflect the contact-load-discharge relationship. However, the determination of urinary lead affected by many factors, large fluctuations. In addition to differences in body, lifestyle and experimental factors, and the determination of the results of the expression of a certain relationship. In view of the domestic methods for the determination of urinary lead are not uniform, the author in the actual work, with four different methods of expression of urinary lead, the practical application, and achieved some experience. Reported as follows now:
