Air pollution in Kagoshima City from April 2002 to March 2003 was investigated with particular emphasis on the falling dust (volcanic ash fall) from Mt. Sakurajima. The falling dust was collected monthly together 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 SO_4^<2->, Cl^-, and water-soluble matter, as well as for pH. The average monthly amount of falling dust at eight locations in Kagoshima City was 6.9 g・m^<-2>・month^<-1>, which was slightly decreased than the value observed in the last fiscal year. Thus, the tendency of low falling dust amount continued, after a period (1999-2000) of relatively high falling dust amount (ca, 50g・m^<-2>・month^<-1>). The weight of water-soluble matter which fell was considerably higher than that for the last fiscal year. NO_2 air pollution was measured by use of the filter-badge method. The highest value for NO_2 concentration was observed at Kagoshima City Hall, however, this figure still meets the value established as the national environmental standard.
