对某冶炼厂锑作业进行职业流行病学调查,空气锑浓度为1.47mg/m3,尿锑排出增高,锑皮炎检出率15.6%;心电图以左室高电压改变明显,5例出现S-T段下降及T波低平;肝功能异常率(31.7%)明显高于对照组(6.3%);上呼吸道损害及肺通气功能下降。表明长期在低浓度锑环境下作业,体内锑吸收增加,皮肤、上呼吸道、心、肝、肺等组织器官仍存在明显损害,提示目前使用的锑卫生标准有必要进行适当修改。
Occupational epidemiological investigation of antimony in a smelter showed that the antimony concentration in air was 1.47mg / m3, antimony in urine increased and antimony dermatitis was detected in 15.6% of cases. The electrocardiogram changed obviously in left ventricular high voltage and in 5 cases S-T segment depression and T wave low level; abnormal liver function (31.7%) was significantly higher than the control group (6.3%); upper respiratory tract damage and pulmonary ventilation decreased. It shows that long-term operation in low concentrations of antimony environment, the body increased absorption of antimony, skin, upper respiratory tract, heart, liver, lung and other tissues and organs are still significant damage, suggesting that the current antimony health standards necessary to make appropriate changes.
