尿铅测定目前多采用双硫腙比色法。此法灵敏度低,分析中干扰因素多,且需要使用毒性药物。随着电化学技术的发展,示波极谱法测定生物样品中的微量金属已逐步得到应用,此法具有较高的灵敏度,且操作简便,快速,适于大批样品的分析。我们结合职工健康建档工作,采集渡口地区140名铅作业工人和随机抽样360名正常人尿样,用热消化双硫腙单色光电比色法与极谱法对照分别测定其尿铅值,
Determination of urinary lead used dithizone colorimetric method. This method has low sensitivity, many interference factors in the analysis, and the need to use toxic drugs. With the development of electrochemical technology, oscillopolarographic determination of trace metals in biological samples has been gradually applied, this method has high sensitivity, and the operation is simple and fast, suitable for a large number of samples. We combined with the work of workers health filing work, collecting 140 lead workers in the ferry area and a random sample of 360 normal urine samples, with thermal digestion dithizone monochromatic photoelectric colorimetric method and polarographic control were measured urinary lead,
