Exciting New Study Reveals Insights into Mercury and Selenium Interaction in Fish
Assessment of dietary Selenium and its role in Mercury fate in cultured fish rainbow trout with two sustainable aquafeeds. We are thrilled to announce the publication of a groundbreaking peer-reviewed paper from the MERFISH project, shedding light on the intricate relationship between mercury (Hg) and selenium (Se) in fish. This paper marks a significant step […]
Marius BIDON defended his PhD thesis on Friday, October 6, 2023 at NUMEA, INRAE-UPPA, Saint-Pée-sur-Nivelle, Congratulations!
Title of the Thesis: Interactions between dietary selenium and mercury in rainbow trout Supervisors: Stéphanie Fontagné-Dicharry and Jérôme Roy.
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 […]
Simple and rapid formic acid sample treatment for the isolation of HgSe nanoparticles from animal tissues
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. […]
First Time Identification of Selenoneine in Seabirds and Its Potential Role in Mercury Detoxification
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, […]
New insights into the biomineralization of mercury selenide nanoparticles through stable isotope analysis in giant petrel tissues.
Journal of Hazardous Materials DOI: https://doi.org/10.1016/j.jhazmat.2021.127922 New article has been published in Science direct in New insights into the biomineralization of mercury selenide nanoparticles through stable isotope analysis in giant petrel tissues. Multipartner research article (IPREM-CNRS, PS Analytical, CEBC, LIENS) Abstract Tiemannite (HgSe) is considered the end-product of methylmercury (MeHg) demethylation in vertebrates. The biomineralization […]
