Abstract
The actual status of air pollution in HCM City is alarming and causing many impacts on human health. The sources of air pollution are classified into four main sources: industrial (point source), transport (line source), area and biological source. The study focused on emission inventory for the area source, including domestic cooking activities, restaurants, cafeterias, petrol stations, photocopy, construction materials stores, construction works, garages, pagodas, straw burning... Emissions inventory method make accurate, reliable and well-defined assessment decisions that show that the use of large amounts of coal and charcoal produces large amounts of gaseous pollutants: TSP, NO2, SO2, CO, CH4 and NMVOC... in which household activities account for about 90% of total emissions and 38% TSP amount of total emissions in the source. Application of GIS tools to develop emission maps for identifying high emission areas. The aim of the study was to point out the main cause of emissions in the source area and areas with high emissions (such as District 3, District 4, District 8, Binh Chanh and Cu Chi) so that solutions created to minimize emissions from the burning of fossil fuel for cooking activities of Ho Chi Minh City’s people would be economical and highly effective...
