Short summary

The granitic material presented lower As(V) adsorption capacity than the mussel shell studied. Fine shell showed moderate As(V) retention (higher than coarse shell). The amendment of 12 and 24 t ha-1 fine shell on the granitic material increased As(V) retention. Most of the adsorbed As(V) did not desorb in a wide range of pH. The adsorbed As(V) was retained mainly on the soluble fraction, with weak bindings, also facilitating release and transfer to water, plants and the food chain.
