Subsequently, it presents recommendations and suitable solutions to minimize air pollution in Ba Ria - Vung Tau Province (BR-VT). To conduct this research, emission factor inventory tools and GIS tools are employed. The results indicate that the significant use of large quantities of LPG, charcoal, and diesel fuel leads to substantial emissions of various pollutants: TSP, NOx, CO, SO2, PM10, PM2.5, and NMVOC. The primary causes of air pollution in BR-VT province stem from mining activities, with major pollutants being TSP, PM10, and PM2.5, having emission loads of 1,860.29
920.19, and 106.61 tons per year, respectively, constituting 97-95% of the total pollution load across the province. Additionally, NOx and CO emissions result from fuel combustion for cooking in households, contributing to 55-78% of the total pollution load. High pollution load areas encompass the towns of Phu My, Chau Duc District, Long Dien District, and Vung Tau City. This study assesses the current emission status of various pollutants and proposes economically viable and effective solutions for air quality improvement in BR-VT province.
