Title
Application of the AERMOD modeling system for environmental impact assessment of NO 2 emissions from a cement complex
Abstract
We applied the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) as a tool for the analysis of nitrogen dioxide (NO 2 ) emissions from a cement complex as a part of the environmental impact assessment. The dispersion of NO 2 from four cement plants within the selected cement complex were investigated both by measurement and AERMOD simulation in dry and wet seasons. Simulated values of NO 2 emissions were compared with those obtained during a 7-day continuous measurement campaign at 12 receptors. It was predicted that NO 2 concentration peaks were found more within 1 to 5 km, where the measurement and simulation were in good agreement, than at the receptors 5 km further away from the reference point. The Quantile-Quantile plots of NO 2 concentrations in dry season were mostly fitted to the middle line compared to those in wet season. This can be attributed to high NO 2 wet deposition. The results show that for both the measurement and the simulation using the AERMOD, NO 2 concentrations do not exceed the NO 2 concentration limit set by the National Ambient Air Quality Standards (NAAQS) of Thailand. This indicates that NO 2 emissions from the cement complex have no significant impact on nearby communities. It can be concluded that the AERMOD can provide useful information to identify high pollution impact areas for the El A guidelines. © 2011 The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences.
