Item Metadata only The applications of the air dispersion model (ISCST) and geographic information systems (GIS) for determining the areas affected by an emission source case study : the Bangpakong power plant(Mahidol University. Mahidol University Library and Knowledge Center, 2002) Ornprapa Pummakarnchana; Sudhin Yoosook; Sura Pattanakiat; Prayoon FongsatitkulItem Metadata only Air assimilative capacity for sulfur dioxide and nitrogen dioxide in the Eastern and Southern regions of Thailand(Mahidol University. Mahidol University Library and Knowledge Center, 2014) Jaeraya Ruangkawsakun; Sarawut Thepanondh; Suphaphat Kwonpongsagoon; Wanida Jinsartand nitrogen dioxide. Screen View was applied to verify the assimilative capacity result by mean of air pollution dispersion theory. Meteorological characteristics of the study area in the year 2010 were selected in the analysis. For spatial analytical results..., both the Eastern and Southern regions of Thailand were aligned with the coast which has an influence on potential of pollutant dispersion. Overall results indicated that the closer the area to the sea, the higher potential for air pollution dispersionItem Metadata only Assessment of hydrogen sulfide emission and concentration in ambient air using AERMOD model from Saen Saeb canal in Bangkok, Thailand(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Piyapat Saenpao; Sarawut Thepanondh; Suphaphat KwonpongsagoonThis study aims to determine emission of hydrogen sulfide (H2S) from Saen Saeb canal and to assess concentration and dispersion of H2S using AERMOD model, as well as to estimate the potential effect on human health over a lifetime of exposure... to estimate H2S concentrations using the AERMOD dispersion model. Results of the study showed that H2S concentrations under the scenario with 24 and 14 hours canal-boat operation were about 67.6% and 67.5% higher than that scenario without canal-boat operationItem Metadata only Using PRTR database to assess human toxicity and eco-toxicity : a case study on emissions source in Rayong province, Thailand(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Krisda Chidsanit; Sarawut Thepanondh; Sopa Chinwetkitvanichaims to apply the USEtox Model and AERMOD Model for evaluating human toxicity and ecological toxicity respectively. Concentrations and dispersions of pollutants are evaluated based on the data achieved from the Pollutant Release and Transfer Registers... CTUe) and paraquat dichloride (2.48E+07 CTUe). It was found that these harmful substances are mainly emitted from agricultural activities. Assessment of atmospheric concentrations and spatial distributions was carried out using the AERMOD dispersionItem Metadata only Assessment of re-suspended road dust in the Na Phra Lan pollution control zone(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Tipawan Phetrawech; Sarawut Thepanondh; Suphaphat Kwonpongsagoon.5 dispersion from different scenarios. Diurnal pattern of ambient PM-10 and PM-2.5 concentrations were evaluated to reveal the contribution of road dust emissions to particulate concentrations in the air. Results indicated that road dust greatly influencedItem Metadata only A study of AERMOD tiering approach for nitrogen dioxide prediction in Maptaphut Industrial Area(Mahidol University. Mahidol University Library and Knowledge Center, 2015) Supitchaya Tunlathorntham; Sarawut Thepanondh; Suphaphat Kwonpongsagoonfor their ability in predicting NO2 ambient concentration in the study area. The performance evaluation of the AERMOD dispersion model in predicting 1-hour average concentrations in the vicinity of the Maptaphut industrial complex was conducted for the years 2012Item Metadata only Application of Aermod in evaluation of assimilative capacity of air pollutants in Maptaphut industrial area(Mahidol University. Mahidol University Library and Knowledge Center, 2016) Apiwat Thawonkaew; Sarawut Thepanondh; Sopa Chinwetkitvanich; Chutarat ChompunthAssimilative capacities of sulfur dioxide (SO2) and oxides of nitrogen (NOx) from industrial and vehicular sources in Maptaphut industrial area in Thailand were evaluated in this study. AERMOD dispersion model (Version 9.1.0) was simulated
