Abstract
Nagasaki is located in the western end of Japan, and receives aerosol factors from the Eurasian Continent such as Asian dusts first in Japan and directly with almost no mixing of the domestic factors. With attention to this geographical situation of Nagasaki area and for the environmental study of Omura bay, we have measured the aerosol size and the concentration of 210Pb and 7Be adhering to the aerosol. Seasonal variation of these data was analyzed combined with the weather data, of the rainfall and the wind direction. We observed simultaneously at two points, in city and in the suburbs, to estimate refloat and the effects of human. We analyzed elements in rainfall and atmosphere. We will present and discuss some result from the analysis.
