| 内容記述 | In order to clarify the regional characteristics of acid rain in Chiba Prefecture, data of precipitation obtained during the period from April 1998 to March 1999 with the aid of the environmental monitoring volunteers of the Institute of Environmental Studies of Keiai University were analyzed. The results of the analyses are summarized as follows : 1) For pH mean value distribution diagram in the warm period in fiscal 1998,the highest with over pH5.25 was in Kurimoto and near Mobara, and the pH value decreased for the circumference. 2) The highest value for pH mean value distribution diagram in the cool season was over pH5.5 in the inland from Kurimoto to Yachimata is distributed, and pH5.0 or less near Funabasi in the West. 3) NO_3^-/nss-SO_4^<2-> ratio (N/S ratio) of the Northern Region in Chiba Prefecture was generally higher than the preceding year. N/S ratio of the region in the north was under 1.0 in the warm period. A value under 0.8 was together distributed near Kashima marime industrial district and Keiyo industrial area in the cool season. 4) The pH distribution and fractional acidity [H^+]/([nss-SO_4^<2->]+[NO_3^-]) distribution in the warm period showed very good correlation. The relationship between pH and fractional acidity (A) in the warm period in Choshi is shown in the following equation. pH=-3.18A+5.90 r=-0.83 And, the relationship between pH and fractional acidity (A) in cool season is shown in the following equation. pH=-3.57A+5.82 r=-0.93 | |||||||||||
