Researching the Potential Impact of Industrial Stacks of the Bright International Vietnam Company on the Ambient Environment

Abstract

Air pollution due to stacks emission is the biggest problem threatening the sustainable development of Bac Ninh province. As one of the economic development centers of the country, Bac Ninh has many industrial zones and major factories, causing air pollution to become more and more serious. In this study, the AERMOD model was used to evaluate the impact of the stack emission from 72 industrial stacks of the Bright International Vietnam factory. Hourly monitored emission data for five consecutive days is fed in the AERMOD model with the hourly meteorological data taken from the ERA5 dataset from 1/1/2018 to 31/12/2020.  The maximum 1-HR, 24-HR, 99th percentile, and annual average concentrations of TSP, SO2, and NO2 were simulated within the 20km x 20km domain of 100m x 100m grid resolution. Air dispersion simulation is performed on the observed background gas concentration of the everyday environment. The simulated spatial distribution of gases indicates the strong fluence of the mountainous topography on the dispersion of stack emission. Results also revealed that the emission potentially causes serious TSP pollution over the region if the exhausted gases are not properly treated.
