摘要
目的:室内空气污染的动态效应。方法:对商场、宾馆、洗浴中心和居民住宅中甲醛、氨、颗粒物等室内空气污染物的采样、检测分析。结果:商场等天井式结构的建筑内,污染物浓度在天井部位大于四周(P<0.05),高层大于低层(相关性显著)。局部的通风不良使得污染物浓度累加,大大的超过国家标准。在中央空调系统管道中积尘的粉尘分散度高层远端大于低层近端,即远离主送风管道粒径有变小的趋势。结论:室内空气污染在不同的建筑几何结构中表现为相应的、动态的变化规律,污染物的天井效应、局部累加效应、颗粒物的撞击分散效应是对其一定规律的总结。
Objective：To study the dynamic effects of the indoor air pollution. Methods：The samples of indor air pollutants such as formaldehyde, ammonia, particulate matter collected in market, hotel, bath center and resident＇ s house were analyzed. Results.In the courtyard type structure buildings, the density of pollutants was higher than that around （P 〈 0. 05 ）, the high layer was higher than the lower （ relativity is remarkable）. Local adverse ventilation resulted in the accumulation of pollutant heavily exceeding the national standard. The dispersed degree on the senior layer far end was greater than the lower close end a- mong the systematic pipeline in central air conditioner, namely far away from the mainly blowing pipeline, one had the tendency to diminish directly. Conclusion： The indoor air pollution is shown as the corresponding, dynamic change law in different struc- ture of geometry of building, courtyard effect, local pollutant accumulation effect, striking of particulate matter disperse effect certain summary of law their.
