Limited effects of increased CO2 and temperature on metal and radionuclide bioaccumulation in a sessile invertebrate, the oyster Crassostrea gigas
International audience This study investigated the combined effects of reduced pH and increased temperature on the capacities of the Pacific cupped oyster Crassostrea gigas to bioconcentrate radionuclide and metals. Oysters were exposed to dissolved radiotracers (110mAg, 241Am, 109Cd, 57Co, 54Mn, an...

Oysters were exposed to dissolved radiotracers (110mAg, 241Am, 109Cd, 57Co, 54Mn, and 65Zn) at three pH (7.5, 7.8, 8.1) and two temperatures (21°C and 24°C) under controlled laboratory conditions.
