| Microplastics are ubiquitous in aquatic ecosystems, but little information is currently available on the dangers and risks to living organisms. In order to assess the ecotoxicity of environmental microplastics (MPs), samples were collected from the beaches of two islands in the Guadeloupe archipelago, Petit-Bourg (PB) located on the main island of Guadeloupe and Marie-Galante (MG) on the second island of the archipelago. These samples have a similar polymer composition with mainly polyethylene (PE) and polypropylene (PP). However, these two samples are very dissimilar with regard to their contamination profile and their toxicity. MPs from MG contain more lead, cadmium and organochlorine compounds while those from PB have higher levels of copper, zinc and... |

| Martinique is a French overseas department whose economy relies heavily on agriculture. Organochlorine pesticides, mainly chlordecone, were used for banana cultivation to eradicate banana weevil over a period of 40 years. Chlordecone is chemically stable,and has a strong affinity for fatty tissues. It is therefore able to bioaccumulate in animals and thereby represent a threat to ecosystems and man. Soils from banana plantations in Martinique are heavily contaminated with chlordecone. Possible transfer of these molecules from agricultural watersheds to the aquatic environment and the organisms that live in it is feared. The hypothesis that ecosystems of Martinique might be highly contaminated with this organochlorine pesticide was investigated. Chlordecone... |

| Cet article de synthèse décrit la composition et l'organisation des végétations colonisant les berges de la lagune Ebrié et fournit des données originales sur l'évolution récente de ces associations consécutivement à l'introduction accidentelle de 2 nouvelles espèces de macrophytes flottantes (Salvinia molesta et Eichhornia crassipes). Un historique de l'invasion de ces 2 espèces en Côte d'Ivoire est présenté et restitué dans un cadre plus général retraçant à partir d'un travail bibliographique l'expansion mondiale et plus spécifiquement africaine de ces 2 espèces. Une étude comparative des compositions chimiques (C,N,P)des 3 espèces de macrophytes aquatiques flottantes (Eichhornia crassipes, Salvinia molesta, Pistia stratiotes) colonisant la lagune Ebrié... |
