Evaluation du transfert des composés organiques des MIOM utilisés en sous-couche routière dans des ouvrages de construction récente

Abstract : The management of the Municipal Solid Waste Incineration Bottom Ashes (MSWI-BA) and their reuse in the road construction are controlled by the regulation of 1994, 9th May. The organic components as PolyChloroDibenzo-para-Dioxines (PCDD) and PolyChloroDibenzoFurannes (PCDF) are not taken into account by the regulation. In this study, two scenarios of MIOM recycling are investigated: the embankment and the subgrade layer. Investigations were conducted to determine the PCDD/PCDF content and profiles of different congeners in the MSWI-BA used in the road construction. The eventual release of these components in the underlying soil was also estimated to evaluate the impact on the environment. The auscultation were realized in two sites containing MSWI-BA produced in 2002 and 2003. The MSWI-BA from the recent incinerator has revealed a weak PCDD/PCDF content varying from of 6,6 to 20 ng I-TEQ/kg MS. The PCDD/PCDF content in the underlying soil are in the same order of magnitude than the content of the reference soils sampling out of the MSWI-BA influence and the soils sampled in the urban zone, indicating no transfer of PCDD/PCDF from MSWI-BA to surrounding soil.
