Abstract
Measurements of atmospheric concentration of NOx and SO2 were carried out by using the chemiluminescence method of NOx and the ultraviolet-fluorescence method of SO2, and by using the training ship Fukae-maru of Kobe University of Mercantile Marine in the sea areas of 0saka Bay and Seto-inlands Sea. Measurement results make clear the folIowings. ( 1) The exhausts from ships have obvious impacts on NOx and SO2 concentration in the narrow water areas and/or in the ports where marine traffic is congested. (2) The atmosphere of the north-east area of Osaka Bay is highly polluted in some weather conditions such that the wind due to large scale pressure systems is weak and the land-and-sea breeze is prevailing.
