This study focuses on a laboratory experimental injection of CO2through calcareous and siliceous sediments both in freshwater and seawater aimed to identify the physical and chemical effects of CO2seepage and to assess the ability of the system to return towards the original conditions once the CO2injection is stopped. A rapid acidification of the water column during the CO2injection and reduction in the dissolved oxygen concentration was measured as well as enhanced weathering of the sediments. A partial recovery towards the initial values of pH has been recorded following the stop of the CO2injection.
