1983年7月,在南汇县卫生防疫站举办的学习班上,由上海市卫生防疫站对尿中氨基乙酰丙酸的测定方法作了统一部署。 我站检验室与劳卫科配合完成了全县铅作业工人健康监护安全指标的检验工作,总样品数为193件。在具体进行氨基乙酰丙酸的检验过程中,根据方法介绍,在显色后以醋酸乙酯调节零点,分别读取试剂空白及样品测定管的光密度,然后用样品光密度读数减去试剂空白光密度读数,所得差值即为计算尿中氨基乙酰丙酸含量的依据。据此,我们随机选取了40名铅作
July 1983, at the Nanhui County Health and Epidemic Prevention Station held by the class, the Shanghai Municipal Health and Epidemic Prevention Station on the urine of aminolevulinic acid determination of a unified approach. I station laboratory and Department of Health and Safety with the completion of the county lead workers in health monitoring safety indicators of the inspection, the total sample number of 193. In the specific process of aminolevulinic acid test, according to the method introduced in the color after adjusting the zero point with ethyl acetate, respectively, read the reagent blank tube and sample tube optical density, and then subtracted with the sample optical density reading reagent blank Optical density readings, the resulting difference is calculated urine amino levulinic acid content basis. Accordingly, we randomly selected 40 lead
