开发了大气和雨水中过氧化氢和有机过氧化物的测量方法，并研究了这些过氧化物对森林的影响。京都大气 H 值的季节变化 (0.18 ppbv) 显示夏季最大值和冬季最小值。 6月和9月，甲基氢过氧化物(MHP)主要在大气中检测到，含量为0.07 〜 0.29 ppbv。大气中的有机过氧化物在约.25℃以上增加，并与O 3 浓度和相对湿度相关，而大气中的H 2 O 2 与相对湿度呈负相关。它们与太阳辐射和紫外线辐射无关。夏季雨水中H 2 O 2 浓度高于50 µM。 6 月和 8 月期间，在雨水中检测到羟甲基氢过氧化物 (HMHP) 和 MHP 作为有机过氧化物，浓度低于 2 µM。
The measurement of hydrogen peroxide and organic peroxides in the atmosphere and rainwater was developed, and the behavior of these peroxides affecting forests was investigated. The seasonal variation of atmospheric H in Kyoto (0.18 ppbv) showed a summer maximum and a winter minimum. Methylhydroperoxide (MHP) was mainly detected in the atmosphere with a level of 0.07 〜 0.29 ppbv during June and September. Organic peroxides in the atmosphere increased above ca .25 ℃ , and correlated with the O 3 concentration and relative humidity, while atmospheric H 2 O 2 was inversely correlated with the relative humidity. They were not related to solar radiation and UV radiation. The H 2 O 2 concentration in rainwater was higher than 50 µ M in the summer. Hydroxymethylhydroperoxide (HMHP) and MHP as organic peroxides were detected in rainwater with low concentrations of less than 2 µ M during June and August.
