摘要
本文用徽章式NO_2个体采样器对15名健康、不吸烟的妇女,接触室内外空气中NO_2的污染水平进行了监测。结果表明:室内无NO_2污染源时,室外NO_2浓度高于室内,个体接触水平介于室内外两者之间,室内存在NO_2污染源时,厨房的浓度高达40plb,室内浓度高于室外。试验者一周中有92％的时间是在室内度过,因此,室内NO_2浓度对人体健康的影响不容忽视。作者认为,对个体、室内和室外采取同时监测的方法,能真实的反映人体接触NO_2的水平。
15 Subjects from health, non-smoking women living in urban area were investigated for NO, personal exposure level for one week. NO, of indoor/outdoor air was also investigated.The results showed: The average NO2 exposure level of outdoor air was higher than that of indoor air if there were no NO2 emission sources indoors. NO2 exposure level of the subjects were bewteen that of indoor and outdoor air.But when there were NO2 emission sources indoors,the iodoor NO2 concentration was higher than outdoors, especially up to 40ppb in kitchen.Since the subjects spent 92% time indoors, the effect of indoor NO2 concentration on human health is very important. In authors' opinion, it will represent the personal exposure level better if the NO2 concentrations indoors and outdoors and personal exposure level are measured at the same time respectively.
