Résumé
DDT transformation to DDD in soil is the most commonly reported pathway under anaerobic conditions. A few instances of DDT conversion to products other than DDD/DDE have been reported under aerobic conditions and hardly any under anaerobic conditions. In particular, few reports exist on the anaerobic degradation of DDT in African tropical soils, despite DDT contamination arising from obsolete pesticide stockpiles in the continent as well as new contamination from DDT use for mosquito and tsetse fly control. Moreover, the development of possible remediation strategies for contaminated sites demands adequate understanding of different soil processes and their effect on DDT persistence, hence necessitating the study. The aim of this work was to study the effect of simulated anaerobic conditions and slow-release carbon sources (compost) on the dissipation of DDT in two tropical clay soils (paddy soil and field soil) amenable to periodic flooding. The results showed faster DDT dissipation in the field soil but higher metabolite formation in the paddy soil. To explain this paradox, the levels of dissolved organic carbon and carbon mineralization (CH
