We undertook two laboratory experiments to study the change of concentrations and the preferential elution of major ions and hydrogen peroxide during melting of a homogeneous snow pack. The elution sequence was as follows : alkali metals, alkaline-earth metals and protons > anions > NH 4 + > H 2 O 2 . We explain the late elution of Cl-, NH4 + and H 2 O 2 by high ice/water partition coefficients and a more even distribution of the two ions as well as of H 2 O 2 within the ice crystal due to formation processes of snow particles in the atmosphere.
