Trace elements in Antarctic fish species and the influence of foraging habitats and dietary habits on mercury levels
International audience This study aims at describing and interpreting concentration profiles of trace elements in seven Antarctic fish species (N = 132 specimens) off Adélie Land. Ichthyofauna plays a key role in the Antarctic ecosystem, as they occupy various ecological niches, including cryopelagi...
