Simulation of CO2 leakages during injection and storage in sub-seabed geological formations: Metal mobilization and biota effects
To assess the potential effects on metal mobilization due to leakages of CO2 during its injection and storage in marine systems, an experimental set-up was devised and operated, using the polychaete Hediste diversicolor as the model organism. The objective was to study the effects of such leakage in...
