Description
Air pollution in Kagoshima City from April 2016 to March 2017 was investigated with particular emphasis on the dust fall (volcanic ash fall) from Mt. Sakurajima. The dust fall 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 dust fall at eight locations in Kagoshima City was 21.0 g·m-2·month-1, which was 40% decrease from that observed in the last fiscal year. The concentration of NO2 in the air was measured by using the "filter-badge method". The average NO2 concentration at the eight locations was 6.1 ppb, which was about the same as that observed in the last fiscal year.
