Abstract
© 2015, Thai Society of Higher Eduation Institutes on Environment. All rights Reserved. Contribution of each type of industrial group to ambient concentration of SO2 and NO2 in Maptaphut industrial area, Thailand was evaluated in the study. AERMOD dispersion model was used to simulate for the maximum 1-hr and annual average concentration within modelling domain in the year 2013. Industrial emission sources were grouped into 5 types namely 1) Gas separation plant, 2) Metal, 3) Petrochemical industry, 4) Power plant and 5) Refinery, respectively. Totally, 422 stack sources were used as input data in this analysis. Results revealed that the maximum 1-hr average ground level concentrations of SO2 and NO2 were dominated by contributions from power plant group. Maximum annual average concentrations of these pollutants were mainly from Petrochemical industry group emissions. Therefore, controlling of SO2 emission from Power plant group and NOx emission from Petrochemical industry group should be given priority for appropriate controlling and management of these air pollutants in this industrial area.
