Abstract

Marine traffic in Osaka Bay is very intensified and much atmospheric pollu- tant (S0% and N0%) from ships is released but there is no regulation about the ship emission. In this paper, we investigated the emission amounts of SO*, NO* and HC from car, factory and ships in Osaka bay area and estimated the influence of the ship emission on the atmospheric pollutant concentration, using both the meteorological prediction model and the at- mospheric pollutant concentration prediction model including the dry depo- sition and the chemical reaction. In Osaka bay area, the emission amounts of SO% and NO% from ships were about 30 % of the
