Emission sources identification in a vinicity of the municipal solid waste incinerator of Toulon in the South of France

Abstract
The aim of this preliminary study is the identification and the apportionment of atmospheric sources influencing the quality of ambient air in the vicinity of MSWI of Toulon. A multivariate receptor model, Unmix, has been applied to ambient elementary concentration data of PM10 fraction measured at five sites around the MSWI. Four composition profiles have been estimated : a marine source (Na-Mg), re-suspended particles (Ti-Ai), an industrial source (Ba-Cu-Fe) and a fourtlii source characterised by Zn-Ca association. The marine source (40% of the total contribution) is the major source influencing the ambient air. This is in accordance with the coastal environment of the study area. The re-suspended particles (23%) is a mixing of soil and industrial dust coming from urban area. The analysis of meteorological data at two sites localise at the north of MSWI show that both industrial (19%) rand Zn-Ca (17%) sources could corne from MSWI.
