CARACTERISATION PHYSICO-CHIMIQUE ET TRACAGE DES EMISSIONS PARTICULAIRES METALLIQUES D'UNE USINE D'INCINERATION D'ORDURES MENAGERES DANS L'AIR AMBIANT. Exemple de l'UIOM de Toulon (Var, France)

Abstract : The aims of this study are the physico-chemical characterisation, the apportionment and the following of particulate heavy metals from MSWI emissions. Various methods (in situ data treatment, unmixing models and codes, UNMIX or CMB, sequential extractions and extented X-ray absorption fine structure (EXAFS) agree in the following: - identification of the MSWI source in two profiles (Zn – Ca et Ba – Cu – Fe – Zn – Pb – Ca); - estimation of its contribution of up to 25% of the total sources contribution; - showing the seasonal variability in term of profile and contribution of this source; - suggest the potential of emitted elements to enter the food chain; This EXAFS first approach on atmospheric particulate matter shows that zinc and lead are in an atomic environment with calcium, silicium and aluminum. In spite of disputable conclusions, isotopic lead ratios define a “MSWI” end-member and confirm that the town-center of Toulon is outside the MSWI plume influence.
