EDTA促排尿铅值,能较好地作为反映体内活性铅量的指标,其标准国家尚未作统一规定。近年来,各地在铅作业职业病普查中,普遍应用测定尿铅作为铅中毒诊断的重要依据,但由于影响尿铅排泄的因素较多,一次尿样不能完全反映体内铅负荷状况。因此,我们试图通过127名铅作业工人驱铅后24小时尿铅绝对值,对其诊断意义及标准问题进行初步讨论,现报告于下。
EDTA lead urinary excretion, can better reflect the amount of lead in the body index, the standard country has not yet made uniform provisions. In recent years, various occupations in the lead occupational disease survey, the general application of determination of lead in urine as an important basis for the diagnosis of lead poisoning, but due to the impact of urinary lead excretion of many factors, a urine sample can not fully reflect the body’s lead load. Therefore, we tried to discuss the significance of the diagnostic value and the standard of urine by measuring the absolute value of urinary lead 24 hours after removing lead from 127 lead workers. We report the following.
