Facing public health priorities, authorities are concerned with environmental issues, such as water resource protection and soil preservation. In urban areas, former craft and industrial areas and water management practices are potential sources of diffuse pollution. Technicians to evaluate the impact of pollution usually use risk assessment tools, but developments are needed to take into account the physical and biochemical complexity of urban soils. This work carried out within the framework of a multidisciplinary research project is aimed at understanding the influence of mixed contamination on the adsorption/release phenomena of pollutants. Samples from two experimental sites will be analyzed for trace metals and organic substances. Analytical procedures should be developed to extract the pollutant-bearing phases before identification. Then experiments will be performed to study the speciation of pollutants as they are released and propose a model of soil-pollutant interactions.
