 note = {The falling vocanic ashes erupted from Mt.Sakurajima were monthly collected together with rain water from April 1981 to March 1982 at 14 locations in Kagoshima city and 7 locations in Sakurajima.
The mixed sample were filtered and the filtrates were analyzed for SO^<2->_4, Cl^- and water-soluble matter.
Some residual ashes were analyzed for the content of acetone-extractive matter and the grain cize distribution.
Heavy metal ions in both the residual ashes and the filtrates of some locations were determind.
The amounts of salfur oxides absorbed on a PbO_2-candle which had been set at 19 locations for a month were also determined.
The results obtained showed that the volcanic ashes falled in this period at Sakurajima 1521 ton/km^<2> a month, on the average. This value was higher than that obtained in last period.
Maximum arsenic of the residual ashes was 32 ppm, which was detected at Arimura - haisuichi in September.
Three locations, Sakurajima hospital, Sakurajima-so, and Arimura - haisuichi were polluted by sulfur oxides more extensively than the other locations being polluted.},
