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: 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

merfish Simple and rapid formic acid sample treatment for the isolation of HgSe nanoparticles from animal tissues

Analytica Chimica Acta DOI 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 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, […]
