| Research Abstract |
In this study, a long range transport and deposition model (OPU-Model) was developed. The source-receptor relationship of acidic pollutants was estimated by the model. The contribution of pollutants emitted at China was larger in Kyushu and Japan Sea-side regions than in Kanto area. Emission inventories of sulfur dioxide and nitrogen oxides in China for 2030 and carbon dioxides for 2010 were predicted. The critical load of Japanese soil for acid deposition was estimated and it was proved that the corrosion of materials due to dry and wet depositions of pollutants was useful as a indicator of environmental impact assessment.
An available control strategy was estimated by the following conditions for Chinese sulfur emission which have not been taken measures nowadays. Those were to minimize the total control cost, to be under the allowable load of soil for deposition of sulfate and under the environmental standard for sulfur dioxides concentration in the atmosphere and to use either fuel exchange or engineering technology as a control method. By the estimation, the emission must be decreased to 40% of 2010's inventory. The control strategy is mainly a shift from crude coal to selected coal. It is recognized that the reduction of sulfur emission leads to the reduction of carbon dioxides. If the control is practiced to satisfy environmental allowable levels of sulfur dioxides and sulfate deposition in China, the contribution rate of acidic deposition on Korea and Japan by Chinese emission source will reduce by half.
