广州市住宅室内PM_(2.5)排放源的定量计算

QUANTIFICATION OF PM_(2.5) INDOOR EMISSION SOURCE INTENSITY IN RESIDENCE OF GUANGZHOU CITY

对广州市部分采样住宅室内、室外PM2.5的浓度进行了15 min平均的实时监测.室内浓度系列与室外浓度系列相比,出现多个明显的浓度峰,定性判断住宅室内存在一定的排放源.结合物质平衡模型、线性回归模型及室内外实时监测浓度线性拟合情况,定量计算住宅室内PM2.5排放源源强,结果表明3个采样住宅的PM2.5室内排放源的平均排放强度为6 417-9 779μg.h-1.

15 minute average real time determinations of PM2.s were perfomed for indoor and outdoor in several residences of Guangzhou. By comparing the indoor PM2.5 concentration series with the outdoor PM2.5, some obvious concentration peaks were found for indoor series, according to which it was considered that there were indoor emission sources of PM：. 5. Combining mass balance model and linear regression model with indoor/outdoor real time concentration series of PM：.5, indoor emission source were quantified. It was found that average indoor emission source intensity of 3 residences ranged from 6 417 to 9 779 μg·h^-1.
