大気中のNO_xおよびSO_2濃度の海上計測 Measurements of Atmospheric Concentration of NO_x and SO_2 in the Sea Areas of Osaka Bay and Seto-inlands Sea
Measurements of atmospheric concentration of NO<I><SUB>x</SUB></I> and SO<SUB>2</SUB> were carried out by using the chemiluminescence method of NO<I><SUB>x</SUB></I> and the ultraviolet-fluorescence method of SO<SUB>2</SUB>, and by using the training ship Fukae-maru of Kobe Universtiy of Mercantile Marine in the Sea Areas of Osaka Bay and Seto-inlands Sea.<BR>Measurements results make clear the followings. (1) The exhausts from ships have obvious impacts on NO<I><SUB>x</SUB></I> and SO<SUB>2</SUB> concentration in the narrow water areas and/or in the ports where marine traffic is congested. (2) The atmosphere of the north-west area of Osaka Bay is highly polluted in some weather conditions such that the wind due to scale pressure systems is weak and the land-and-sea breeze is prevailing.
