Interaction between dietary selenium and methylmercury on growth performance, deposition and health parameters in rainbow trout fed selenium-rich tuna-based diets or selenium-poor plant-based diets

Aquaculture DOI: https://doi.org/10.1016/j.aquaculture.2023.739550 Multipartner research article (INRAE, IPREM-CNRS, IMR) Abstract This study evaluated the effect of dietary mercury (Hg) and selenium (Se) sources and levels on growth performance, Hg and Se accumulation, pro-inflammatory cytokine levels and global health parameters in rainbow trout juveniles. A 6-month feeding trial was carried out with a control plant-based diet (containing analyzed Se and […]

Analytica Chimica Acta DOI https://doi.org/10.1016/j.aca.2023.340952 Multipartner research article (IPREM-CNRS, UCM, CEBC, LIENS) Abstract The present work explores for the first time the potential of formic acid on the extraction of tiemannite (HgSe) nanoparticles from seabird tissues, in particular giant petrels. Mercury (Hg) is considered one of the top ten chemicals of major public health concern. […]

Environmental Science & Technology DOI https://doi.org/10.1021/acs.est.1c04966 Multipartner research article (IPREM-CNRS, PS Analytical, CEBC, LIENS) Abstract Birds are principally exposed to selenium (Se) through their diet. In long-lived and top predator seabirds, such as the giant petrel, extremely high concentrations of Se are found. Selenium speciation in biota has aroused great interest in recent years; however, […]
