In order to make sure the pollution of these acids, an attempt was made to measure pollutants in snow on road sides by ion chromatography. At the chance of a heavy snowfall, 53 samples in 1 km2 area of the Yokohama National University's campus were collected, and then chloride ion, sulfate ion and nitricion were simultaneously measured on ppm level. The distribution figure of ion concentrations plotted on the map showed that chloride and sulfateions accumulated only near a road, and the background values of these ions of natural origin covered the other area. On the other hand, nitricion was seemed to spead widely in the urban area.}, pages = {61--64}, title = {積雪のイオンクロマトグラフ分析による幹線道路の塩素および硫酸汚染分布結果}, volume = {12}, year = {1985} }
