金属汞对作业工人生殖结局影响的流行病学调查

An epidemiocological survey on the effects of metallic mercury on reproductive outcome of workers

对经呼吸道接触金属汞工人的生殖流行病学调查表明，接触汞工人（工作场所空气汞浓度范围０．００１～０．２００ｍｇ／ｍ３）的神经系统症状、消化系统症状检出率均显著高于对照组，接触汞男工的性欲明显减退。职业性接触金属汞对女工月经先兆症状积分影响不大，但痛经检出率显著高于对照组。接触汞女工及男工妻子的先兆流产率显著高于对照组，而对生殖结局未观察到明显影响。

A retrospective study was designed to investigate the reproductive toxicity of mercury and was carried out in 503 employees who were occupationally exposed to metallic mercury and in 587 non-exposed who worked in food factories.The mercury concentrations in air around the workplace ranged from 0.001 to 0.200mg/m3.It was very notable that the prevalence of the neurological signs,and the digestive system signs in the exposed group were significantly higher than those in the control(P<0.05).The incidence of the decreased libido in the exposed group were significantly higher than that in the non-exposed group(P<0.05),which indicated the possibility of adverse effect of mercury on male reproductive system. The premenstrual symptoms between the two groups were not significant(P>0.05).The rate of dysmenorrhea in the exposed group(16.90%) was significantly higher than that in the non-exposed group(10.77%)(P<0.05),which indicated that the occupational exposure to metallic mercury might induce higher rates of abnormal menstruation. The proportions of threatened abortion in female workers and male workers'wives were also significantly higher in the exposed groups(3.77%,3.60%) than those in the control(0.96%)(P<0.05).No difference was found in reproductive outcome between the two groups.
