  • 1. Summary Soil vapour migration into buildings, and subsequent inhalation, are often the main exposure pathway to humans at sites contaminated with Volatile Organic Compounds (VOCs).The validation of these models is still incomplete, beyond some global verification of indoor air concentrations: step by step measurements for a detailed model calibration and "validation" hardly exist in the literature, and predictions of indoor air concentrations from different models sometimes vary by...
  • The sedimentary materials are unconsolidated and very heterometric (from clay to rolling cobbles), with an heterogeneous composition (from limestone and sandstone to metamorphic and igneous rocks).However, concentrations of chlorinated solvent degradation products such trichloroethene (TCE), cis-dichloroethene and trans-dichloroethene (cis-DCE,The regional average natural net infiltration value is approximately 150 mm/y.

  • A.DEGRAEVE, G.POUILLE, E.REYNAUD (RENAULT) I.1. Description I.1.1. Situation The RENAULT site “Trapèze and Seguin Island” is located in the middle of an urban zone, along the river Seine (Fig.1).Fig.2: First investigations according to historic studies Fig.3: Four scenario for future urban site The results of these diagnostics allowed us to realise DRAs (Detailed Risk Assessment) These DRAs led to determine the clean-up level for the different substances potentially present on...
  • This experience is discussed here with regard to major questions on stakeholders' participation in site assessment and management, such as the communication between experts and non-experts and between experts of different fields (health scientists vs. environmental engineers), the impact of the media, The discussion integrates other experience gathered on stakeholders' involvement It leads to the identification of some ingredients for an efficient stakeholders' participation,...
