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。
In this paper, a total of 193 female workers in three battery factories were harmed by lead. The survey results showed that the physical and reproductive functions of women workers were damaged to some extent under the exposure conditions of over 9.5 times the lead concentration in the operating environment. (P <0.05). The detection rate of abnormal menstruation increased with the increase of seniority. The detection rate of spontaneous abortion rate in lead exposure group was (P <0.05). However, the detection rate of stillbirth was 2.19 times of the control group in lead exposure group, but there was no significant difference between the two groups (P> 0.05). The paper also investigated the relationship between mother-to-child lead load.
