Abstract

Air pollution in Kagoshima City from April 2008 to March 2009 was investigated with particular emphasis on the falling dust (volcanic ash fall) from Mt. Sakurajima. The falling dust was collected monthly with rainwater at eight locations in Kagoshima City. After the sample had been filtered, the residue was dried and weighed, and the filtrate was analyzed for SO42-, Cl-, and water-soluble matter, as well as for pH. The average monthly falling dust at the eight locations in Kagoshima City was 11.5g•m-2•month-1, which was about twice as much as that observed in the last fiscal year. Although the tendency of low falling dust have continued since 2001, the falling dust increased for this year. The concentration of NO2 in the air was measured by use of the "filter-badge method". The average NO2 concentration at the eight locations was 7.1 ppb, which was somewhat lower than that for the last year.
