Application of Modelling Tools for Air Quality Management in Giao Long Industrial Zone, Ben Tre Province, Vietnam.

The Giao Long industrial zone (IZ) is one of the important IZs in the socio-economic development of Ben Tre Province, Vietnam. Air quality management in Giao Long IZ has yet to achieve high efficiency. This study developed data on air pollution emissions from the production activities of enterprises and applied model system, The Air Pollution Model (TAPM) - The AMS/EPA Regulatory Model (AERMOD), to simulate the distribution of air pollution from the IZ to its surroundings. Research results show the following: (i) the emission load from coal combustion is significantly higher than that of other commonly used fuels, with 75% NO2, 77% CO, 100% SO2 and 99% TSP; (ii) simulation results show that the average 1-hour and 24-hour highest and annual concentrations of NO2, CO and TSP are lower than the National Technical Regulation on Air Quality in Vietnam - QCVN 05:2013/BTNMT; in particular, for SO2, the average 1-hour and 24-hour highest concentrations were 1.6-fold and 1.2-fold higher than QCVN 05:2013/BTNMT; and (iii) based on the results of the simulation and assessment of the impact of air pollution on the surrounding areas, the study proposed some solutions to improve efficiency in air quality management at Giao Long IZ. In addition, the study developed scenarios to reduce SO2 emissions by enhancing SO2 treatment efficiency in enterprise emissions. in addressing water-related problems and for sustainable water resource management.
