“…The deposition of contaminated particles that occurred in slow water flows increased the exposition level of animals to chlordecone, through their surrounding environment. This hypothesis agreed with other studies that reported increasing chlordecone biocontamination in turbid zones of the rivers (high suspended particulate concentrations, high sedimentation) (Luellen et al, 2006;Nichols, 1990). During the wet season, the recurrent floods standardized habitats (rapid running waters went through the whole study reach) and precluded the deposition of suspended matter, limiting the mass of pollutant available for biota.…”

This paper determines the bioaccumulation and transfer processes of organochlorine pesticides within the stream food web in Guadeloupe (Caribbean). ABSTRACTConcentrations of organochlorine pesticides and stable isotope ratios of nitrogen and carbon were measured in a tropical freshwater ecosystem to evaluate the contamination level of biota and examine the bioaccumulation patterns of pollutants through the food web. Chemical analyses showed a general and heavy contamination of the entire food web. They revealed the strong accumulation of pollutants by juveniles of diadromous fishes and shrimps, as they re-enter the river. The role of ecological factors in the bioaccumulation of pesticides was evaluated. Whereas the most persistent pollutants (chlordecone and monohydro-chlordecone) were related to the organisms diet and habitat, bioaccumulation of β-HCH was only influenced by animal lipid content. The biomagnification potential of chlordecone through the food chain has been demonstrated. It highlighted the importance of trophic transfer in this compound bioaccumulation process. In contrast, bioconcentration by passive diffusion from water seemed to be the main exposure route of biota to β-HCH.

“…Today, this persistent organic pollutant continues to contaminate aquatic ecosystems in different parts of the world (Coat et al, 2011;Cornish et al, 2007;Luellen et al, 2006;Roche et al, 2011). In the French West Indies, CLD can be found in most environmental compartments: soil, water, plants and animals (Bertrand et al, 2010;Clostre et al, 2015;Gourcy et al, 2009;Jondreville et al, 2014;Levillain et al, 2012).…”

“…It was found that more than 90,000 kg of kepone was released into the atmosphere. The soil adjacent to the manufacturing plant was contaminated in the range of 2-6 lg of kepone per gram (Luellen et al 2006). Similar situation is found in Caribbean, where chlordecone was used in the amounts of 3 kg per hectare per year in 1970s and 1980s, leading to the pollution of 45% of agriculture area in Martinique, 8% of which is considered to be contaminated with more than 1 mg/kg of dry matter of Kepone (Fournier et al 2017), providing threat to inhabitants (Clostre et al 2017).…”

Persistent organic pollutants are a serious problem to the environment due to their toxicity to both fauna and flora. Extremely resistant to biodegradation and prone to transfer through long distances via atmosphere can contaminate almost any place in the planet. They tend to bioaccumulate in fat tissue due to their lipophilicity and seriously affect poisoned organism's nervous, hepatic, reproductive or hormonal system. Since 2009, due to the Stockholm convention on persistent organic pollutants production and utilisation of certain halogenated pesticides has been prohibited. This group includes hexachlorocyclohexane, chlordecone (kepone) and pentachlorobenzene. All of these chloropesticides pose a serious threat to environment, and careful control of their production and release to the environment is required. This paper is a review of physical and chemical properties as well as sources in environment, impact on animal organisms, methods of degradation of most broadly used chlorinated persistent organic pollutants and suggestions concerning their utilisation.
