我们对从事汞作业的新工人(男性109例,女性65例,)进行了所在车间汞浓度与体征和尿汞的两年动态观察。结果表明:一年内新工人在空气汞浓度相近情况下,尿汞与汞作业工龄之间呈平行关系;并且空气汞浓度与尿汞相应浓度成1∶0.5～1的比例。在空气汞浓度超国家标准3倍,工龄<两年者,尿汞与体征呈平行关系。故不能一概而论尿汞与汞作业工龄问无平行关系以及尿汞与症状体征及一些功能检查结果之间平行关系。在空气汞浓度略高于国家标准,均值在0.012mg/m~3时,一年以上就可能发生汞吸收;四年后,发生汞吸收占30.6％。因此,我国现行汞浓度标准0.01mg/m~3,尚欠完善。
We conducted a two-year dynamic survey of mercury concentrations and signs in our workshop and urinary mercury on new workers engaged in mercury work (109 males and 65 females). The results showed that the new workers in a year in the case of similar concentrations of mercury in urine mercury and mercury working length of service was parallel between the relationship; and the concentration of mercury and mercury in urine corresponding concentration of 1: 0.5 ~ 1 ratio. Mercury concentration in the air over the national standard 3 times the length of service <2 years, urinary mercury and signs were parallel. It can not be generalized urinary mercury and mercury work length of service asked no parallel relationship between urinary mercury and symptoms and signs and some functional test results between the parallel relationship. In the air slightly higher than the national mercury concentration, with a mean of 0.012mg / m ~ 3, more than one year may occur mercury absorption; mercury absorption occurred after four years accounted for 30.6%. Therefore, our current mercury concentration standard 0.01mg / m ~ 3, still not perfect.
