本文报告锰作业女工的月经先兆症状乳房胀痛、嗜睡、失眠、乏力等显著高于对照组。接触水平0.4mg/m ̄3以下,锰作业女工月经周期缩短和经期延长;锰接触水平超过0.4mg/m ̄3时,月经异常,月经周期、经期延长和痛经的发生率明显增多,呈明显的剂量-反应关系。锰对子代的影响如出生缺陷、新生儿窒息、新生儿死亡、低体重儿及儿童智力和生长发育异常的发生率与对照组相比并无明显差异;而出生缺陷的发生率虽无统计学意义,但已超过全国出生缺陷平均发生率(13‰),RR为2.6,提示锰对于代出生缺陷有一定的潜在危险性。
This article reports that female migrant workers of manganese work aura symptoms of breast pain, drowsiness, insomnia, fatigue and other significantly higher than the control group. Exposure level 0.4mg / m ~ 3 the following, manganese working women shorten the menstrual cycle and menstrual prolongation; manganese exposure levels over 0.4mg / m ~ 3, menstrual abnormalities, menstrual cycle, menstrual period and the incidence of dysmenorrhea increased significantly, Significant dose-response relationship. The impact of manganese on offspring such as birth defects, neonatal asphyxia, neonatal death, low birth weight children and children with mental retardation and growth and development rates compared with the control group no significant difference; the incidence of birth defects, although no statistics However, it has surpassed the national average incidence of birth defects (13 ‰) and the RR was 2.6, suggesting that manganese poses some potential risk to generation defects.
