Receptor modelling is one of the application of multivariate analysis dealing with the identification and quantitative apportionment of air pollutants to their potential sources. Various statistical multivariate models including principal component analysis-absolute principal component scores (PCA-APCS) have been proposed to identify and to ascertain the contribution of different sources to monitored ambient concentrations. Many studies have been reported on the apportionment of the PM, but most of them are focused only on the inorganic species of PM10, and there are only few works dealing with the apportionment of PM2.5 monitored near incinerator plants. In this work the amount and distribution of both inorganic and organic components of PM2.5 were investigated and PCA-APCS method applied for source apportionment.

Abstract
Receptor modelling is one of the application of multivariate analysis dealing with the identification and quantitative apportionment of air pollutants to their potential sources. Various statistical multivariate models including principal component analysis-absolute principal component scores (PCA-APCS) have been proposed to identify and to ascertain the contribution of different sources to monitored ambient concentrations. Many studies have been reported on the apportionment of the PM, but most of them are focused only on the inorganic species of PM10, and there are only few works dealing with the apportionment of PM2.5 monitored near incinerator plants. In this work the amount and distribution of both inorganic and organic components of PM2.5 were investigated and PCA-APCS method applied for source apportionment. The daily PM2.5 samples were collected in a monitoring station placed in the maximum impact area of the incinerator fallout previously determined by ADMS-Urban, a gaussian modified dispersion model.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
