International audience In the French West Indies (Caribbean), the insecticide Chlordecone (CLD) has been extensively used to reducebanana weevil (Cosmopolites sordidus) infestations in banana plantations. Previous studies have shown high CLDconcentrations in freshwater and coastal communities of the region. CLD concentrations, however, have not yetbeen assessed in marine top predators. We investigated CLD concentrations in cetacean blubber tissues fromGuadeloupe, including Physeter macrocephalus, Lagenodelphis hosei, Stenella attenuata and Pseudorca crassidens.Chlordecone was detected in all blubber samples analysed, with the exception of four P. macrocephalus.Concentrations (range: 1 to 329 ng·g−1 of lipid weight) were, however, lower than those found in species fromfresh and brackish water.
