| influence of biological and ecological factors on the bioaccumulation of polybrominated diphenyl ethers in aquatic food webs from french estuaries. | previous studies have shown the worldwide presence of six congeners of polybrominated diphenyl ethers (pbdes) in marine biota (bde-28, -47, -99, -100, -153 and -154). the objective of the present study was to document their presence, their level and their transfer in the food web of two major estuaries in france, the loire and the seine. pbdes were quantified in eight principal species from the loire, representing primary consumers (the bivalve scrobicularia plana), omnivores (the worm nereis di ... | 2006 | 16764911 |
| thyroid endocrine status of wild european eels (anguilla anguilla) in the loire (france). relationships with organic contaminant body burdens. | in teleost fish, thyroid function is involved in various critical physiological processes. given the complexity of the hypothalamo-pituitary-thyroid (hpt) axis, a large number of genes and proteins can be the potential target of endocrine-disrupting compounds (edcs). the aim of this study was to evaluate, in yellow and silver european eels (anguilla anguilla), potential effects of edcs on thyroid status by analyzing the associations between edc body burdens and thyroid hormones (ths). in yellow ... | 2016 | 26845177 |
| occurrence of pops and other persistent organic contaminants in the european eel (anguilla anguilla) from the loire estuary, france. | the chemical contamination of the loire estuary by three classes of persistent organic pollutants (pops): the polychlorinated biphenyls (pcbs), the polybrominated diphenyl ethers (pbdes) and the perfluorinated and polyfluorinated alkyl substances (pfas), and three families of organic contaminants, the alkylphenols (aps), the polycyclic aromatic hydrocarbon metabolites (oh-pahs) and the bisphenol a (bpa) were investigated in the muscles and bile of european eel (anguilla anguilla). yellow eels (n ... | 2015 | 25461022 |
| dioxin-like, non-dioxin like pcb and pcdd/f contamination in european eel (anguilla anguilla) from the loire estuarine continuum: spatial and biological variabilities. | to characterize the eel contamination by dioxin-like (dl) and non dioxin-like (ndl) polychlorinated biphenyls (pcbs) and polychlorinated dibenzo-p-dioxins and furans (pcdd/fs), sixty-two eels from the loire estuary (france) were analyzed. pcb contamination significantly increased from glass eel stage (3.71 ± 1.85 and 15.2 ± 4.2 ng g(-1) dw) to other life stages (for yellow eels: 62.8 ± 34.4 and 382 ± 182 ng g(-1) dw; for silver eels: 93.7 ± 56.3 and 463 ± 245 ng g(-1) dw respectively for dl and ... | 2014 | 24317164 |
| vg mrna induction in an endangered fish species (anguilla anguilla) from the loire estuary (france). | estuarine zones are extremely fragile due to increasing stress from anthropogenic activities. among those, the loire estuary (france) is potentially exposed to various contaminants including endocrine disruptors compounds (edcs) able to impact the reproduction physiology of fish. the european eel (anguilla anguilla), endangered fish species, is apparently not relevant, in its yellow stage, to monitor the effects of endocrine disruption. despite this weakly responsiveness, this study aimed to inv ... | 2013 | 23993220 |
