説明

Samples of volcanic ashes from Mt. Sakurajima were collected monthly at l4 locations in Kagoshima City and at 7 locations in Sakurajima from April 1, 1983 through March31, 1984. The samples collected were filtered, the residues were dried and weighed, and the filtrates were analyzed for pH, SO_4^{2-}, Cl^-, and water-soluble matter. The amounts of sulfur oxides absorbed by PbO_2-candles which had been placed at 19 of the above mentioned locations were also determined monthly. The highest amount of volcanic ashes in this fiscal year was 19,393ton/km^2/month, which was recorded at Kurokami Middle School in October. This is also the highest value recorded during the last 6 years. The highest amount of sulfur oxides absorbed by the PbO_2-candles in this fiscal year was 2.26mg/100cm^2/day, which was observed at Sakurajima-so in December. Acidification of rain was observed at all locations, and the strongest acidity of the rain collected was pH2.8 which was recorded at Sakurajima Middle School in November.
