本文总结了某氯碱车间的卫生学调查,汞作业工人(55名)和对照组(50名)的体检和实验室检查,表明汞作业工人的临床表现较对照组显著多见,指颤只出现在接触空气中汞浓度高于0.05mg/m~3的修槽、电解工中,汞作业工人的血、尿汞水平显著高于对照组(P<0.001)。以群组分析,血、尿汞水平与作业环境空气中汞浓度的高低呈平行关系。汞对工人肾功能的影响,只出现在尿汞55μg/g肌酐以上的修槽工。
This paper summarizes the hygiene surveys of a chlor-alkali plant, physical examinations and laboratory tests of mercury-exposed workers (55) and control groups (50), indicating that clinical manifestations of mercury-exposed workers are significantly more common than controls and that episodic tremor only occurs In contact with the repair tank with mercury concentration higher than 0.05mg / m ~ 3 in the air, the blood and urine mercury levels of mercury workers in electrolysis workers were significantly higher than those in the control group (P <0.001). Group analysis, blood and urine mercury levels in the working environment and the level of mercury in the air was a parallel relationship. The effect of mercury on the renal function of workers appears only in repair workers exposed to urinary mercury 55 μg / g creatinine.
