摘要
分夏、冬季采集南昌大学前湖校区室外和3个不同室内环境中的PM2.5,测定有机碳(OC)和元素碳(EC),并分析室内、外碳气溶胶质量浓度及其分布特征;利用OC-EC关系式半定量分析室内排放源;结合室内、外二次有机碳(SOC)和SOC/OC的分布进一步讨论不同室内排放源的特征及对SOC的影响;对4个采样点的8个碳组分丰度特征比较分析,结果表明复印/打印机对室内OC的贡献高,8个碳组分的丰度分布特征与其它排放源具有较明显的差异。
Ambient PM2.5 and indoor PM2. s were collected in Qianhu campus of Nanchang University during June 2009 and January 2010, and were analyzed for organic and elemental carbon（OC and EC）. Distribution characteristics of PM2.5 and OC, EC were discussed. Indoor OC was higher than that in outdoor,but indoor EC was lower than that in outdoor, reflecting indoor OC sources existing. OC-EC relationship equation was used to analyze indoor OC sources semi-quantificationally. Combining the indoor/outdoor secondary organic carbon（SOC） and SOC/OC characteristic to sampling environment, indoor OC sources and effects on SOC were considered. Eight carbon components contributions on total carbon （TC） in 4 sampling sites were compared, and it was found that copycat and printer exhaust contributed high OC and presented different eight carbon distribution characters.
