【摘要】 甲醛被世界卫生组织列为一级致癌物,广泛存在于现代封闭式办公居住空间,对人体危害甚大。WHO以及国标根据甲醛对鼻子和喉咙的刺激阀值,建议室内甲醛的浓度值为不高于0.1mg/m3。但实际上室内空气污染是混合的,探讨混合污染时危害性的评价方法十分必要。本文采用果蝇作为受试生物,建立动态暴露浓度控制实验系统,实验研究不同湿度条件下甲醛浓度变化对果蝇生命周期的影响,并通过数据分析,探讨湿度对果蝇生命周期的影响,为建立混合空气污染评价果蝇生命周期模型积累基础数据。更多还原

【Abstract】 Formaldehyde which is harmful to human body and exist indoor air widely is recognized as carcinogen by the World Health Organization. Base on the stimulus threshold on nose and throat, its’ concentration indoor air is limited below 0.1mg/m3. In fact, people are exposed to the indoor air which is a variety of mixed in chemical pollutants, the study of these mixed pollutants is necessary. This paper chose fruit flies as experimental animal, research flies’ life cycle under different formaldehyde concentration and relative humidity. By analyzing the trend of death, this paper hopes to provide reference for indoor air quality evaluation.更多还原
