Source Apportionment and Chemical Composition of PM10 in University Classrooms of Changsha,China
Classroom PM10 (diameter of particulate matter ＜10μm) of Central South University of Changsha,China were monitored and collected by Tapered Element Oscillating Microbalance 1400a (TEOM 1400a) and Automated Cartridge Collection Unit (ACCU) during the period of September,2007 to March,2008.All these samples were analyzed by X-ray fluorescence (XRF) for elemental concentration.Principal component analysis (PCA) and absolute principal components analysis (APCA) were applied in source apportionment.Results showed PM10 pollution in classroom had higher concentration than that of outdoors and PM10 24h concentration standard of China.Five sources were obtained by source apportionment in classroom: soil and chalk dust (49.78%),coal burning (31.55%),incineration and chlorine based cleaning (8.2%),industry (8.02%),and traffic (2.45%).Five types of classroom are classified according to their indoor and outdoor environments.Results showed indoor and outdoor environments of them,really effect chemical composition and source contributions of PM10 in them.
