Bioaccumulation of rare earth elements in juvenile arctic char (Salvelinus alpinus) under field experimental conditions
Few ecotoxicological studies exist on the accumulation and effects of rare earth elements (REEs) in fish, particularly on Arctic species. In southwest Greenland, there are currently several advanced exploration REE mining projects. The aim of this study was to investigate accumulation of REEs in nat...
