为了研究铅和镉对混合接触这些金属的工人肾功能方面的交互作用,作者选择尿镉>2微克镉/克肌酐,血铅≥35微克铅/100毫升血,尿铅≥50微克铅/克肌酐,以及血铅≥35微克铅/毫升血和尿铅≥50微克铅/克肌酐同时存在的62名接触铅和镉的工人,还进行了肾功能及其有关生化指标的测定,并将本次测定结果与上次对三组工人(铅接触组、镉接触组、不接触这两种金属的对照组)测定的结果进行了比较。结果证明:中等度地接触无机铅(血铅<62微克/100毫升,平均接触时间13.2年)对肾功能无影响,只是对
In order to investigate the renal effects of lead and cadmium on workers exposed to these metals, the authors chose urinary cadmium> 2 μg Cd / kg creatinine, blood lead ≥35 μg lead / 100 ml blood, urine lead ≥50 μg lead / g Creatinine, and 62 lead and cadmium exposed workers whose blood lead was ≥ 35 μg lead / mL blood and urinary lead ≥ 50 μg lead / kg creatinine were also tested for renal function and their biochemical markers The results of the measurements were compared with those of the last three workers (lead exposure group, cadmium exposure group, control group not exposed to both metals). The results show that: medium exposure to lead (blood lead <62 micrograms / 100 ml, the average contact time of 13.2 years) had no effect on renal function, but right
