| 内容記述 | In our college, Chiba Keiai Junior College(CKJC), the observations of the acid rain have been conducted as a part of environmental education program since April, 1993. The results of the observation in and around Sakura-City from April to September, 1993,are summarized as follows : 1 . The average pH value of the sample of the precipitation which are collected with every rainfall in the period is 5.06,and 77% of the precipitations is occupied by acid rain. 2. All precipitations in April and May can be recognized to be acid rain. The pH values of these are stable, whereas after June the values show violent variation. 3 . When the low pressure passes through stationary front which is on the south coast of Japan Island, all of the precipitations become acid rain, and then, the lowest pH value of the precipitations in all the observations, I.e. , 3. 68,is observed. 4 . Near Narita International Airport, extremely high values of NO_3^- /SO_4^2-> concentration rasio (NS ratio) in rain are observed. | |||||||||||
