测定尿铅可估算其真正的接触水平,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的影响,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的关系。鉴于国内对尿铅测定结果的表示方法尚不统一。笔者在实际工作中,用四种不同的尿铅结果表示方法,进行了实际应用,取得一定的应用价值。1 材料与方法 1.1 尿样 系印刷厂接触铅作业工人。 1.2尿铅测定方法 按文献进行。双
Determination of urinary lead can estimate the true level of exposure, but also reflect the contact, load, discharge relationship between. However, the determination of urinary lead is influenced by many factors and fluctuates greatly. In addition to the difference of body, lifestyle and experimental factors, there is a certain relationship between the determination of urinary lead and the method of determination. In view of the results of the determination of urinary lead that the method is not uniform. In the actual work, the author uses four different methods of urinary lead expression to carry out practical application and obtain certain application value. 1 Materials and Methods 1.1 Urine sample printing plant contact with lead workers. 1.2 Determination of urinary lead according to the literature. double
