Limited effects of increased CO2 and temperature on metal and radionuclide bioaccumulation in a sessile invertebrate, the oyster Crassostrea gigas
The combined effects of reduced pH and increased temperature on the capacities of the Pacific cupped oyster Crassostrea gigas to bioconcentrate radionuclide and metals and the bio-accessibility of Mn, Zn and 241Am were found during experimental in vitro simulation of human digestion.
Ocean acidification increases cadmium accumulation in marine bivalves: a potential threat to seafood safety
The results obtained suggested that all species tested accumulated significantly higher Cd in the CO2 acidified seawater during the 30 days experiment and the health risk of Cd via consumption of M. meretrix at pH 7.8 and 7.4 significantly increased 1.21 and 1.32 times respectively, suggesting a potential threat to seafood safety.
Evaluation of the Effect of Local Water Chemistry on Trace Metal Accumulation in Puget Sound Shellfish Shows That Concentration Varies With Species, Size, and Location
Global climate change is causing ocean acidification (OA), warming, and decreased dissolved oxygen (DO) in coastal areas, which can cause physiological stress and compromise the health of marine
Investigations of temperature and pH variations on metal trophic transfer in turbot (Scophthalmus maximus)
Assimilation efficiencies of Co and Ag in juvenile turbot, determined after a 21-day depuration period, were not affected by pre-exposition to the different environmental conditions, while pH variations did not affect the assimilation of any of the metals studied.


Effects of increased pCO2 and temperature on trace element (Ag, Cd and Zn) bioaccumulation in the eggs of the common cuttlefish, Sepia officinalis
The results suggest that pH and temperature affected both the permeability properties of the eggshell and embryonic metabolism, and the need to further evaluate the likely ecotoxicological impact of the global change on the early-life stages of the cuttlefish.
Contrasting bioaccumulation and transport behaviour of two artificial radionuclides (241AM and 134CS) in cuttlefish eggshell
The bioaccumulation of both radionuclides displayed saturation kinetics with steady state in uptake being reached in 10 d for Am-241 and 6 d for (CS)-C-134, indicating a poor affinity of Cs-134 for the embryonic tissues of cuttlefish.
Biokinetics of zinc and cadmium accumulation and depuration at different stages in the life cycle of the cuttlefish Sepia officinalis
Food is the likely primary pathway for Zn and Cd bioaccumulation in S. officinalis, and the digestive gland plays a major role in the subsequent storage and presumed detoxification of these elements regardless of the uptake pathway, tracer experiments indicate.
Uptake, transfer and distribution of silver and cobalt in tissues of the common cuttlefish Sepia officinalis at different stages of its life cycle
This observation demonstrates that substantial metal transfer takes place from several organs to the digestive gland, and further highlights the major role this organ plays in metal storage and detoxification processes in these cephalopods.
