  abstract = {{P}urpose {T}he use of chlordecone ({CLD}) has caused pollution of soils, which are now a source of contamination for crops and ecosystems. {B}ecause of its long-term impacts on human health, exposure to {CLD} is a public health concern and contamination of crops by {CLD} must be limited. {T}o this end, we conducted field trials on chlordecone sequestration in soil with added compost. {M}aterials and methods {T}he impact of added compost on chlordecone sequestration was measured in nitisols. {A}fter characterization of the soil, the transfer of chlordecone from soil to water was assessed in a leaching experiment and from soil to two crop plants in a nitisol plot. {F}inally, to understand the underlying processes, changes in {CLD} content were measured in soil fractions and soil porous properties were assessed after the addition of compost. {R}esults and discussion {A} rapid seven-fold decrease in water extractable {CLD} was observed in amended soils. {F}ive percent amendment led to a significant reduction in the contamination of crops by {CLD}; edible radish tubers were 50% more contaminated without added compost and cucumber fruits were 60% more contaminated. {A}fter the addition of compost, {CLD} content increased in the fraction of pre-humified or partially mineralized organic debris. {F}inally, in contrast to andosols, adding compost to nitisols did not affect the soil microstructure. {C}onclusions {I}ncreasing chlordecone sequestration by adding compost could be an alternative solution until soil decontamination techniques become available. {T}his could be a provisional way to control further release of {CLD} from contaminated soils towards other environmental compartments.},
