Murododaira(海拔2450米)西坡雾水化学成分的测量。从2004年到2007年，每年秋天都会在日本海海岸附近表演Tateyama。2005年秋季，高山气团频发强酸性雾(pH <； 4)，其中含有高浓度的−。Tateyama主要起源于亚洲受污染的地区。雾水中NO3-−/NSSSO42-−的比值在2004年和2007年较高。2006年检测到来自粉尘颗粒的高浓度nss钙离子。背景KOSA粒子可能在自由对流层中占主导地位，并可能在2006年秋季中和酸性雾。2005年10月还观察到了高浓度的海盐成分。海盐粒子可能是被强台风从太平洋输送过来的，并观察到了明显的镁离子损失。有时还会检测到对植被危害严重的100g/μM以上的过氧化物质。
Measurements of the chemical composition of fog water at Murododaira (altitude, 2,450 m), on the western slope of Mt. Tateyama near the coast of the Japan Sea, were performed each autumn from 2004 through 2007. Strong acidic fogs (pH < 4) containing high concentrations of nssSO42−were frequently observed in the autumn of 2005, when the air mass at Mt. Tateyama originated mainly from the polluted regions of Asia. The ratio of NO3−/nssSO42−in fog water was relatively high in 2004 and 2007. High concentrations of nssCa2+derived from dust particles were detected in 2006. Background Kosa particles might have been predominant in the free troposphere and could have neutralized acidic fogs in the autumn of 2006. High concentrations of sea-salt components were also observed in October 2005. The sea-salt particles might have been transported from the Pacific Ocean by a strong typhoon, and significant Mg2+loss was observed. Peroxides higher than 100 μM, which are seriously harmful to vegetation were sometimes detected.
