摘　　要：2014年4—5月,在对南京某高校居住区室内和室外的大气污染物PM10进行采样、监测的基础上,分析并讨论其具体的分布特征和影响因素.结果表明:该居住区室内外PM10日均质量浓度基本满足国家二级排放标准(PM10日均浓度小于150μg/m3),只有少数情况下超过国家二级排放标准;室内污染物浓度变化较室外污染物浓度变化有滞后;温度、相对湿度、大气压和天气条件与PM10质量浓度呈现出一定的关联性.Based on indoor and outdoor air pollutants PM10 sampling and monitoring data in the residential area ofa university in Nanjing from April to May in 2014,we discussed the distribution characteristics and factorsinfluencing of these PM10. The results showed that the average daily residential indoor and outdoor concentrations ofPM10 basically meet the national emission standards,just over the national emission standards in a few cases. Incomparison,the indoor pollutant concentration changes are lagged behind in the concentration of pollutants thanoutdoor.Temperature,relative humidity,barometric pressure,weather conditions and PM10 mass concentrationsshowed some correlation.
