Source Apportionment and Chemical composition of particulate matter (PM10) in university classrooms

Artikel i vetenskaplig tidskrift, 2009

The inhalable particulate matter (PM10) was continuously monitored and sampled in the classrooms of Central South University at Changsha by Tapered Element Oscillating Microbalance 1400a (TEOM 1400a) from September to December, 2007. The chemical compositions of the PM10 samples were analyzed by the X-ray fluorescence (XRF), and then the source apportionment of the classroom particles was investigated by the principal component analysis (PCA). The results show that the mean PM10 concentration in classrooms is (176.56±57.63)
