Marine air pollution (NOx,SOx) from ships have an advance effect on the environment causing acidification, formation of ozone, nutrient and contributes to adverse health effects globally. The emissions evaluation of air pollutions from the ships to the land have been one of the important subjects because those emissions plays an important role in relation to regional area such as Osaka Bay. The 1st stage regulation for NOx value is now being put into practice (from May 2005) by IMO. The 2nd & 3rd stage regular forms will come into force on coming 2011 & 2016. The NOx exhausted quantities in Japan is 72,000ton (SOx: 27,000ton) in 2000, occupies for 30% of the total quantities. The existence of diffusion date on the land is with metrological phenomenon, but there exists no the diffusion date on the sea surfaces nowadays. Because there are so many influencing parameters for diffusion model on the sea surfaces, it is not easy to determine quantitatively. This study is simulated by Off-shore and Coastal Dispersion Model of Godden. This input date for simulation is measured in Osaka Bay by A.I.S. of T.S “Fukaemaru”.
