Myoko and adjacent region from 18-19 March 1991. Conductivity, pH and concentrations of the major ions of the samples were measured. pH was found to range from 4.58 to 5.27, the mean being 4.72. The pH at sites with relatively deeper snowcover was found to be somewhat lower. The obtained concentrations of chloride and sodium ions which strongly affected by seasalt during the northwest monsoon were significantry lower than in the precipitation samples from other sites situated at an equal distance from the northwestern seacoast line in Niigata Prefecture. The lower nitrate to sulfate ratios, expressed as equivarents, indicated sulfate to possibly be largely responsible for the precipitated acidity in this region.}, pages = {105--110}, title = {妙高山麓地域における早春の積雪中に含まれる酸性降下物}, volume = {6}, year = {1991} }
