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 SO_4^<2->, Cl^-, and water-soluble matter, as well as for pH. The average monthly falling dust at eight locations in Kagoshima City was 8.1 g・Em^<-2>・month^<-1>, which was somewhat higher than that observed in the last fiscal year. The tendency of low falling dust has continued since 2001. The concentration of NO_2 in the air was measured by use of the filter-badge method, and it was found that the NO_2 air pollution was not so serious in the city.}, pages = {93--98}, title = {鹿児島市の大気汚染調査(第18報) : 平成16年度調査報告}, volume = {47}, year = {2005} }
