铅是古老而常用的金属,其毒性对生殖和发育的影响在动物实验中已得到证实。1989年对哈市蓄电池厂接铅作业女工137人职业性健康监护做了专题回顾性生殖功能影响的调查。该厂女工137人,平均工龄25.5岁,其中育龄女工96人。厂生产工艺较落后,铅烟尘污染严重。1989年测尘样品全部超标,最低0.11mg/m~3,最高1.57mg/m~3。体检结果说明女工铅危害阳性改变率极显著高于男性。判定生理异常指标的标准为:月经
Lead is an ancient and commonly used metal whose effects on reproduction and development have been demonstrated in animal experiments. In 1989, Harbin City Battery Factory received 137 lead workers in occupational health care workers do a special review of the reproductive function of the survey. The factory workers 137 people, the average length of service 25.5 years old, of whom 96 were women of childbearing age. The factory production process is relatively backward, lead dust pollution is serious. In 1989 all dust samples exceeded the standard, the lowest 0.11mg / m ~ 3, the highest 1.57mg / m ~ 3. The physical examination results showed that the positive rate of change of lead hazard among female workers was significantly higher than that of men. The criteria for determining physiological abnormalities indicators are: menstruation
