Chlordecone is a pesticide very resistant to degradation, that is, with a long lifetime [8] it was used mainly for the protection of banana plantations. Now, chlordecone is becoming a new source of contaminatiOTi for cultivated roots as it is still polluting agricultural soils. In the literature [9], it is shown that allophanic soils retain and trap more pesticides than other kinds of soils. Therefore, allophanic soils could be highly polluted but less contaminated for crops and water, and the clay microstructure should be an important physico-chemical characteristic governing the fate of the pesticide in the environment.
