The fish or the egg : maternal transfer and subcellular partitioning of mercury and selenium in Yellow Perch (Perca flavescens)
Khadra, Mélissa; Caron, Antoine; Planas, Dolors; Ponton, Dominic; Rosabal, Maikel; Amyot, Marc (Elsevier, 2019-04-17)Mercury (Hg) is a trace element of particular concern since it is ubiquitous in the environment and because its methylated form (MeHg) readily bioaccumulates and biomagnifies in food webs. This latter process leads to elevated Hg concentrations in fish ... -
Mapping metal (Hg, As, Se), lipid and protein levels within fish muscular system in two fish species (Striped Bass and Northern Pike)
Charette, Tania; Rosabal, Maikel; Amyot, Marc (Elsevier, 2020-11-19)Current guidelines tend to limitfish consumption based on mercury (Hg) or monomethylmercury(MeHg) content infishflesh, without considering the presence of antagonist chemical elements thatcould modulate Hg toxicity. However, it is difficult to assess ... -
Role of prey subcellular distribution on the bioaccumulation of yttrium (Y) in the rainbow trout
Cardon, Pierre-Yves; Roques, Olivier; Caron, Antoine; Rosabal, Maikel; Fortin, Claude; Amyot, Marc (Elsevier, 2019-12-13)Our knowledge of the processes leading to the bioaccumulation of rare earth elements (REE) in aquatic biota is limited. As the contamination of freshwater ecosystems by anthropogenic REE have recently been reported, it becomes increasingly urgent to ... -
Toxicity and subcellular fractionation of yttrium in three freshwater organisms : Daphnia magna, Chironomus riparius and Oncorhynchus mykiss
Cardon, Pierre-Yves; Triffault-Bouchet, Gaëlle; Caron, Antoine; Rosabal, Maikel; Fortin, Claude; Amyot, Marc (American Chemical Society, 2019-08-15)The demand for rare earth elements (REEs) has increased since the 1990s leading to the development of many mining projects worldwide. However, less is known about how organisms can handle these metals in natural aquatic systems. Through laboratory ...
