本文调查低浓度混苯作业女工及其幼儿共18对的健康情况,与对照组18对比较。苯组女工的月经周期、月经量、痛经、自然流产率、先兆流产和异常分娩率,以及苯组幼儿平均出生体重等、与对照组比较无显著性差异(P>0.05)。体检未发现苯组母亲和幼儿与苯及其同系物有关联的阳性体征。实验室检查,苯组女工血色素和白细胞数均值显著低于对照组(P<0.05),而血小板、胎儿血红蛋白、血红蛋白A_2、外周淋巴细胞微核率和姐妹染色单体互换频率等,与对照组比较无显著性差异(P值均>0.05),苯组幼儿除血色素均值低于对照组幼儿(P<0.05)外,上述其他实验室指标与对照组幼儿比较无显著性差异。
This article investigates the health conditions of 18 pairs of female employees and their children under low concentration mixed benzene, compared with 18 in control group. There were no significant differences in the menstrual cycle, menstrual flow, dysmenorrhea, spontaneous abortion rate, threatened abortion and abnormal delivery rate among the benzene workers and the average birth weight in the benzene group (P> 0.05). Physical examination found no positive group of mothers and children with benzene benzene and its homologues associated positive signs. Laboratory tests showed that the mean values of hemoglobin and white blood cell count in benzene group were significantly lower than those in the control group (P <0.05), while those of platelet and fetal hemoglobin, hemoglobin A2, peripheral lymphocyte micronucleus rate and sister chromatid exchange rate were significantly lower than those in control group There was no significant difference between the two groups (P> 0.05). There was no significant difference between the other laboratory indexes and the control group of children except the average hemotochromia in benzene group was lower than that of the control group (P <0.05).
