Evaluation des composants organiques d'un sol de cokerie en contexte d'atténuation naturelle

Abstract : Coking plant soils are highly heterogeneous and are made of building materials and various organic constituents such as coke, coal, coal -tar and road asphalt. Those materials can strongly influence soil properties. Thus, the retention of the various contaminants will depend on the nature and the degradation of the soil organic constituents. This work deals with the ageing of a coking plant soil and its consequences on the fate of both organic and metallic pollutants. The multi-scale approach applied in this study allows to consider the different levels of complexity through the use of (i) pure compounds, isolated organic fraction of soils such as coal tar and coal and a soil with its mineral fraction, and (ii) experimental devices gradually integrating the processes involved in natural attenuation : laboratory oxidation and biodegradation experiments, simplified device allowing the study of few grams of samples exposed to natural attenuation, and the GISFI (French Scientific Interest Group - Industrial Wasteland) lysimeter plots allowing the study at field scale). Two major evolutions were evidenced: (i) the oxidation led to a condensation suggesting a stabilization process of the organic compartment; (ii) the biodegradation induce the formation of smaller molecular units and the release of organic compounds from the non extractable part of the organic matter. The trends identified during the natural attenuation experiments suggest that the biodegradation is the major process involved in our ageing experiments. The sorption of copper varied according to the different organic constituents that were tested but was clearly enhanced by the degradation of these constituents
