A Study on the Method of Air Quality Management Using TCM Model in Industrial Area

This study was performed to evaluate a applicability of TCM(Texas Climatological Model) model to a industrial area sush as CUNSAN and a possibility to provide necessary informaitons for air quality management The air pollutants were measured at 6 sampling sites of GUNSAN industrial area from june to july in 1989 The model was checked by comparing the observed data with estimated data. The meteorological data for wind direction and wind speed were obtained from the observatory station in GUNSAN. The results are summarized as follows 1. Average concentrations of air pollutants at all sampling sites were; S02 0.011-0.019 ppm‘ NO~ 0.012-0.017 ppm. CO 0.6- 1.0 ppm. TSP 45.8-64.2 μg/ m 2. The emission amounts show that point source are in general higher than area source 3. As a results of correlation analysis , relationship between S02 concentration ill the observed value and estimated value showed positive significance.(r = 0766) 4. The sulfer content of the 1.6% at present to 0.8%, which means a 53.3% reduction. By controlling stack height could be lowered 14.5%. but the effective way of emission control is use of the lower sulfer fuels than controlling stack height. 5. The ratio between S02 contration in the observed value and estimated value showed 1.05. Therefore, the TCM model was qui t.e effective in predicting air quality in GUNSAN industrial area.
