“…In this way, different approaches have previously been used to simulate acidification scenarios due to CO 2 leakages from CCS [13][14][15][16][17]. A set of leaching tests developed by the Nederlands Normalisatie-instituut-NEN, (NEN 7341) or the European Committee for Standardization-CEN, through Technical Specifications-TS, (CEN/TS 15364, CEN/TS 14405 and CEN/TS 14429) or European Standards-EN, (EN12457) are commonly used to determine the influence of pH on the release of inorganic constituents from solid materials.…”

This study provides a better knowledge of key parameters controlling the mobility of Dissolved Organic Carbon (DOC), As, Cd, Cr, Cu, Ni, Pb and Zn from contaminated marine sediment in contact with acidified seawater using static and dynamic standard leaching tests. These procedures have been modified in order to use different leaching agents, L/S ratios, contact times and pH values that simulate seawater acidification under CO 2 leakages scenarios. Studied sediment from a potential area of CO 2 storage, shows a high acid neutralisation capacity (ANC pH=4 =3.58 eq/kg) for deionised water as well as for seawater (ANC pH=4 =3.97 eq/kg). The availability control mechanism is shown by releasing Cd with seawater at pH values 6, 7 and 8 and by the releasing of Zn with seawater at pH 6; the solubility control mechanism appears for Ni release using natural seawater. Experimental results of metal release from the pH dependence leaching test are modelled with Visual MINTEQ geochemical software to predict metal release from sediment, obtaining minor differences with experimental values. An improvement in the metal release results has been obtained considering in the model the influence of the DOC, Fe-and Al-(hydr)oxides, humic acids and fulvic acids. The obtained results would be useful as a line of evidence input for the risk assessment of a Carbon Capture and Storage site where acidified seawater at different concentrations of CO 2 is in contact with sediment.

“…The automotive industry originates wastes such as shredder residue (Péra et al, 2004), paint (Arce et al, 2010) or phosphate coating sludge (PS) (Dogan and Karpuzcu, 2010;Ucaroglu and Talinli, 2012). Phosphating is the most widely applied system for metal pretreatment process.…”

Phosphate coating hazardous wastes originated from the automotive industry were efficiently encapsulated by an acid-base reaction between phosphates present in the sludge and calcium aluminate cement, yielding very inert and stable monolithic blocks of amorphous calcium phosphate (ACP). Two different compositions of industrial sludge were characterized and loaded in ratios ranging from 10 to 50 wt.%. Setting times and compressive strengths were recorded to establish the feasibility of this method to achieve a good handling and a safe landfilling of these samples. Short solidification periods were found and leaching tests showed an excellent retention for toxic metals (Zn, Ni, Cu, Cr and Mn) and for organic matter. Retentions over 99.9% for Zn and Mn were observed even for loadings as high as 50 wt.% of the wastes. The formation of ACP phase of low porosity and high stability accounted for the effective immobilization of the hazardous components of the wastes.
