CO₂ Leakage-Induced Contamination in Shallow Potable Aquifer and Associated Health Risk Assessment

Table 4

Kinetic data for selected primary and secondary minerals. Only calcite was treated similar to the equilibrium reaction, and the rest of the minerals were kinetically treated with consideration of neutral, acid, and base mechanisms.
