本文报告某铅锌矿镉作业者79例的健康检查结果。部分作业者有头晕、四肢发麻、关节酸痛、膝反射减弱、牙齿黄染、肢端挛缩等症状和体征。实验室检查,近1/3作业者尿镉升高,尿β_2-M增高占31.6%,尿总蛋白升高占13.9%。结果表明,该矿镉作业者中,部分人已有过量镉接触及镉吸收,少数人有轻度肾小管功能改变,极少数人有轻度肾小球功能改变。因此,该矿须进一步加强防护措施,继续对作业者进行随访观察。
This article reports the health check-up of 79 cases of lead-zinc mine cadmium operators. Some operators have dizziness, numbness, joint pain, decreased knee reflex, yellow teeth, acral contractures and other symptoms and signs. Laboratory tests, nearly 1/3 of the workers urine cadmium, urinary β 2-M increased 31.6%, urinary total protein increased 13.9%. The results showed that some of cadmium miners in the mine had excessive cadmium exposure and cadmium absorption, and few had slight changes in renal tubular function, while a few had mild glomerular function changes. Therefore, the mine should further strengthen the protective measures and continue to follow-up observation of operators.
