【摘要】 以已内酰胺作业工龄满一年以上的552名女工为观察对象,选作业环境噪声强度与已内酰胺作业车间相近、不接触任何化学物质的516名某纺织厂女工为对照组,用专用调查表由专业人员询问进行回顾性调查,重点调查生育史、月经史以及新生儿情况。结果表明:在己内酰胺浓度低于10mg/M~3的作业条件下,己内酰胺对女工的性机能可产生不良影响,主要表现为:妊娠合并症及月经异常的患病率升高,并观察到原发不孕的患病率高于对照组。更多还原

【Abstract】 The effects of caprolactam on thematernal functions of female workersin a synthetic fibre factory in Beijingwere investigated.552 female workersover one year working history were st-udied by retrospective questionaire ofmenstruation and pregnancy history.516female workers from a certain textilefactory with similar working enviro-nment and noise intensity,but withoutcaptolactam exposure were similarlystudied as controls. The intensity of noise in their wor-king places were 82-88 dB(A),and theconcentration of captolactam in air waslower than 10mg/m~3. Results of the study showed thateven at caprolactam concentration lowerthan 10mg/m~3,it can inflict an effect onthe menstrual functions of the exposedfemale workers as evidenced by:(1) Theprevalence of disturbances of menstr-uation of the exposed female workerswere statistically higher than that ofthe controls(34.5%:25.0%,p<0.005);(2) The incidenc of primary infertilityof exposed group was higher than thatof the controls significantly(2.9%:0.7%,p<0.05) and (3) The frequency of to-xemia of pregnancy of exposed groupwas also higher than that of the cont-rol (10.6%:5.1%,p<0.005).The incidenceof sponta leous abortion and prematurebirth of exposed group was similar tot hat of the control.更多还原
