| Research Abstract |
Snow samples were gathered from Hokkaido Island to Yamagata, Niigata and Toyama Prefectures in the Mainland in winter. By analyzing the chemical characteristics of these samples concerning an acid snow, the actual conditions were investigated.
A lot of findings were obtained concerning the hydrogen peroxide concentration of snow that the reports on its concentration are very little. Some relations were seen among the air pollutant substances, the major ion concentrations, the hydrogen peroxide concentrations, the pH of snow and the snow algae, etc., and the selective elutions of the ion of snowmelt water were observed, though a further observation is necessary for the grasp of a clearer relation.
