【摘要】 本文对三个蓄电池厂共193名女工受铅危害的状况调查结果表明:在作业环境铅浓度超标9.5倍以上的暴露条件下,女工的生理、生殖机能均受到一定的损害。表现为经量减少和月经失调者增多,与对照组间的差异有显著意义(P<0.05),月经异常的检出率随工龄的增长而升高;自然流产率铅接触组检出率为8.36%,对照组为4.56%,差异有显著意义(P<0.05);而死产检出率铅接触组为对照组的2.19倍,但二者之差异无显著性(P>0.05)。本文还对12对母子铅负荷的关系进行了调查分析。更多还原

【Abstract】 This paper reported the investigation of the harmful effects of lead on woman workers who worked in three accumulator battery factories. The results showedthat under the conditions in which concentration of air lead was 9.5 times higher thanthe standard concentnation in the air of the workshops, the woman workers phys-iologioal and reproductive functions were both damaged, the manitestation to be theincrease of hypomenorrhea and irregular menstruation. There was significant differ-ence between the test group and the control group (P<0. 05). The rate of detectedirregular menstruation increased with the length of work-year. The rate of natur-al abortion in the exposed group was 8.36% and was 4.5% in the controlgroup. The difference was of statistical significance (P<0. 05). There was nosignificant difference in the rate of dead birth between the two groups, but the Re-lative Hazard was 2.2 to which more attention should be paid. The relation of moth-er and baby’s lead burden was also investigated. It was shown that the amount of lead in milk increased with the prolonged workday of the mother after deliveryand so the lead in the baby urine increased to. In addition the xcess of lead abs-orption by the children of 2--6 years of age was related to the bad health habithhabits of mothers and the domestic pollution.更多还原
