Abstract
During winter 1985/86 three profiles through a snow cover located at the Swiss Snow and Avalanche Research Institute Weissfluhjoch (Davos) at 2540 m.a.s.l. were analysed for the main chemical impurities including hydrogen peroxide. The concentration profiles of NO3 -, SO4 2-, Cl-, HCOO-, H+, NH4 +, Na+, K+ and Ca2+ do not change as long as the temperature in the snow field is below zero degree celsius. Only the H2O2 content decreases considerably. The disintegration rate depends mainly upon the availability of sunlight, thus photolysis is probably the most important decay process. Organic peroxides are not recorded in the snow.
