![]() ![]() Under the easterly prevailing wind in the dry season, the high pollution was more likely to be experienced in the west of Ho Chi Minh. The results show that the center of HCMC could not receive anymore the emission, even needs to reduce half of the emission. The emission zoning was initially studied by calculating and simulating the loading capacities of each pollutant based on the highest concentration and the National technical regulation in ambient air quality. These values also will increase in 20 if the local government does not have any plan for the reduction of emissions, especially, SO 2 in 2030 also will be 1.02 times higher than that in QCVN 05:2013. ![]() The results show that the highest concentrations of CO, NO 2, and O 3 in 2017 exceeded the National technical regulation in ambient air quality (QCVN 05:2013) 1.5, 1.5, and 1.1 times, respectively. The model is then applied to simulate a retire 1-year period to determine the levels of air pollutants in HCMC in 2017, 20. The model performance was evaluated using observed meteorological data at Tan Son Hoa station and air quality data at the Ho Chi Minh City University of Science. Simulations of air pollution were conducted in Ho Chi Minh City (HCMC), the largest city of Vietnam by using the TAPM-CTM model. The objectives of this research are: (i) Air quality modeling over HCMC by using the TAPM-CTM system model by using a bottom up air emission inventory and (ii) Study loading capactities of air pollutant emissions over Ho Chi Minh City. Many zones in HCMC can’t receive more air pollutants. These high pollutant concentrations have destroyed the human health of people in HCMC. Ho Chi Minh City (HCMC) is one of the cities in developing countries where many concentrations of air pollutants exceeded the Vietnam national technical regulation in ambient air quality including TSP, NO x, Ozone and CO. ![]()
