“…Although, Fernández-Bayo et al (2013) showed the existence of CLD degrading organisms in a tropical soil (andosol) microcosm under aerobic conditions, CLD undergoes no significant or quick biotic or abiotic degradation (Dolfing et al, 2012;Levillain et al, 2012). Driven by the water cycle, CLD in soils is progressively transferred to aquatic ecosystems (Coat et al, 2011) and also in the food web because of its high K oc (Soil Organic Carbon Water Partitioning Coefficient) (15849 L/Kg), K ow (Octanol-Water Partition Coefficient) (4.5-6.0) and its affinity for lipids (Cabidoche and Lesueur-Jannoyer, 2012;Clostre et al, 2013;Sterrett and Boss, 1977;UNEP, 2005;US-EPA, 2008). Human contamination has also been detected in FWI population mainly resulting from consumption of contaminated food, seafood and root vegetables (Dubuisson et al, 2007;Gaume et al, 2014;Guldner et al, 2010).…”

Effects of chlordecone on 20-hydroxyecdysone concentration and chitobiase activity in a decapod crustacean, Macrobrachium rosenbergii

a b s t r a c tChlordecone (CLD) is an organochlorine insecticide abundant in aquatic environment of the French West Indies. However, few studies have investigated its impact on freshwater invertebrates. Whereas CLD is suspected of inducing endocrine disruption, this work aimed to study the effects of environmentally relevant concentrations of CLD on the 20-hydroxyecdysone (20-HE) hormone concentration and on the chitobiase activity, both having key roles in the molting process of crustaceans. In addition, the bioaccumulation of CLD was measured in the muscle tissue of Macrobrachium rosenbergii to underline potential dose-response relationship. The results have shown that CLD was bioaccumulated in exposed organisms according to a trend to a dose-response relationship. Moreover, it was observed that CLD decreased the 20-HE concentration in exposed prawns when compared to control, whatever the duration of exposure, as well as it inhibited the chitobiase activity after 30 days of exposure. The present study indicates that CLD could interfere with molting process of M. rosenbergii by disturbing the 20-HE concentration and the activity of chitobiase, suggesting consequences at the long term on the shrimp development. This study also confirmed that CLD could be an endocrine disruptor in decapod crustaceans, as it was already observed in vertebrates.

“…In addition, although CLD displays high affinity for soil organic matter, its residues leach from agricultural soils to water resources and pollute drinking water in the FWI but also contaminate aquatic biota, including fish and giant shrimp locally called ouassou (Coat et al 2006(Coat et al , 2011. Moreover, due to its biomagnification potential, CLD can be transferred to crops (tuber vegetables; cucurbits) and accumulate in poultry or cattle fed with CLD-contaminated resources (Faroon et al 1995;Le Déaut and Procaccia 2009;Robert 2011;Cabidoche and Lesueur-Jannoyer 2012;Joindreville et al 2013Joindreville et al , 2014. Monitoring contamination revealed the presence of CLD not only in soils but also in rivers, springs, drinking water, and food crop products such as tuber vegetables, cucurbits, food fishing products (shrimp, fish), and food breeding products too (ducks, hens).…”

The insecticide chlordecone applied for decades in banana plantations currently contaminates 20,000 ha of arable land in the French West Indies. Although the impact of various pesticides on soil microorganisms has been studied, chlordecone toxicity to the soil microbial community has never been assessed. We investigated in two different soils (sandy loam and silty loam) exposed to different concentrations of CLD (D0, control; D1 and D10, 1 and 10 times the agronomical dose) over different periods of time (3, 7, and 32 days): (i)

“…Indeed, because of its high Koc (soil organic carbon water partitioning coefficient), Kow (octanol-water partition coefficient), and its affinity for lipids, CLD is persistent in the environment and accumulates in the food web (Cabidoche and Lesueur-Jannoyer 2012). Since Hammond et al (1979) demonstrated that CLD can bind to estrogen receptor in rat, many studies investigated the endocrine effects of CLD in various biological models.…”

Chlordecone is a persistent organochlorine pesticide widely used in Guadeloupe (French West Indies) to control the banana weevil Cosmopolites sordidus. Although it was previously highlighted that chlordecone may affect the reproduction and growth of vertebrate species, little information is available on the chlordecone effects in invertebrates. The present study investigated the effects of chlordecone on a hormone and a protein having key roles in reproduction and growth of the decapod crustacean Macrobrachium rosenbergii, by measuring the 20-hydroxyecdysone concentration, vitellogenin, and vitellogenin receptor gene expression, as well as the bioconcentration of chlordecone in exposed prawns. First, the results revealed that chlordecone was accumulated in M. rosenbergii. Then, it was found that Vg and VgR gene expression were increased in male and female M. rosenbergii exposed to chlordecone for 90 and 240 days, while the 20-hydroxyecdysone concentrations were decreased. This work suggests that chlordecone accumulates in prawn tissues and could affect key molecules involved in the reproduction and the growth of the invertebrate M. rosenbergii. However, many questions remain unresolved regarding the impacts of chlordecone on growth and reproduction and the signaling pathways responsible for these effects, as well as the potential role of confounding factors present in in situ studies.
