目前,在工业卫生工作中评价尿中毒物的浓度时,为了便于相互比较,常用比重校正法或肌酐校正法来校正尿中毒物的浓度。为了考查尿流速对校正的和未校正的尿中11种金属与有机物排泄的影响,使之成为校正尿中毒物浓度的一种简便而易行的方法,本文研究了工人在一定条件下,一天四段时间内尿中毒物的排泄情况。实验步骤如下: 本研究的19名受试者均为男性金属冶炼工人,年龄为34～59岁。接触Pb、Zn、Cu At present, in the evaluation of the concentration of urinary toxicants in industrial hygiene work, in order to facilitate mutual comparison, often used gravity correction method or creatinine correction method to correct urinary toxic concentrations. To examine the effect of urinary flow on the excretion of 11 metals and organics in the corrected and uncorrected urine, making it an easy and feasible way to correct urinary toxic concentrations, this study investigated the effects of urinary flow on a daily basis Four periods of urinary poison excretion. The experimental procedure is as follows: All 19 subjects in this study were male metal smelters, aged 34-59 years. Contact with Pb, Zn, Cu
