摘　　要：我国目前对建筑室内挥发性化学污染物综合作用的研究很少,对室内污染物的“剂量—反应”的研究更为少见。针对此问题,笔者选择果蝇为实验生物,甲醛和苯为室内代表性化学污染物,模拟人类实际生活中的混合污染物暴露模式,对果蝇进行大量的实验。结果表明:(1)果蝇暴露在甲醛和苯单一污染物中,气体浓度越高,果蝇死亡率越大,故可用果蝇死亡率表征室内污染物毒性;(2)甲醛和苯叠加后暴露组的果蝇死亡率远大于同浓度的甲醛和苯单一暴露组,可见叠加后的污染物毒性大大增强。At present,there are few studies on the comprehensive effects for superimposed action of chemical mixtures to human in China,especially the"dose-response"of indoor pollutants.In order to solve this problem,the author chose drosophila as the experimental organism,formaldehyde and benzene as the representative indoor chemical pollutants,simulated the exposure mode of mixed pollutants in human life,and carried out a large number of exposure experiments on drosophila.The results showed that:(1)the higher the concentration of formaldehyde and benzene,the higher the mortality of drosophila(2)the mortality of drosophila melanogaster exposed to formaldehyde and benzene was much higher than that of single exposure group with the same concentration of formaldehyde and benzene.
