  abstract = {{C}hlordecone, an organochlorine insecticide, pollutes soils and contaminates crops and water resources and is biomagnified by food chains. {A}s chlordecone is partly trapped in the soil, one possible alternative to decontamination may be to increase its containment in the soil, thereby reducing its diffusion into the environment. {C}ontaining the pesticide in the soil could be achieved by adding compost because the pollutant has an affinity for organic matter. {W}e hypothesized that adding compost would also change soil porosity, as well as transport and containment of the pesticide. {W}e measured the pore features and studied the nanoscale structure to assess the effect of adding compost on soil microstructure. {W}e simulated changes in the transport properties (hydraulic conductivity and diffusion) associated with changes in porosity. {D}uring compost incubation, the clay microstructure collapsed due to capillary stresses. {S}imulated data showed that the hydraulic conductivity and diffusion coefficient were reduced by 95 and 70 % in the clay microstructure, respectively. {R}educed transport properties affected pesticide mobility and thus helped reduce its transfer from the soil to water and to the crop. {W}e propose that the containment effect is due not only to the high affinity of chlordecone for soil organic matter but also to a trapping mechanism in the soil porosity.},
