Source apportionment of PM2.5 and PM10 at twenty sites across Europe (ESCAPE/TRANSPHORM projects)

H Price, C Hak & R Sokhi

This abstract reports the preliminary source apportionment findings from the analysis of datasets compiled during the ESCAPE project (www.escapeproject.eu). The datasets were analysed in TRANSPHORM (Transport related air pollution and health impacts – www.transphorm.eu) using the receptor modelling programme Positive Matrix Factorization (PMF). An example of the source apportionment results are presented for Athens, which had its highest contributions from traffic (26%). The datasets provide a wealth of information, but were not designed for receptor modelling, which presented challenges in their analysis.
