This study was aimed to investigate the influence on the vicinity by air pollutant generated from facility of the district heating located in local small town. We selected the seven areas around the surroundings of facility of the district heating, compared the air quality evaluated before ,md after operations of the facility, and estimated the diffusion of air pollutant exhausted from the facility using a ISC model. The result was that the concentration of TSP before and after operations of the facility 89~94μg/m³ and 72~81μ g/m³, respectively and the latter showed a decline in concentration. Also, there was no relationship between straight distance from the facility of the district heating and the concentration of TSP. This result was applicable to cases of PM -10 and S0₂. We also investigated the influence on the air around the neighbor area by air pollutant produced from facility of the district heating using ISCLT3 model. The adding-concentrations of TSP, S02, N02, and CO were 0.0019~0.00183μg/m³, 0.0029~0.5648ppb, 0.2924~1.9837ppb, and 0.0087~0.0590ppb, respectively. It is predicted that each concentration is added to pollutant exhausted from facility of the district heating and is about 1/100~1/180, 000 of present air quality. This has a tiny influence on general air quality. According to this analysis, the concentration of air pollutant is less effected to pollutants expected by the facility of the district heating than other pollutants emitted from mobil source or industrial complex, and etc.
