Air in Ho Chi Minh city is polluted by PM2.5 (particle matter with the diameter is less than 2.5 μm, so-called PM2.5), O₃, CO, NO₂ and TSP which greatly affects public health. Ho Chi Minh City (HCMC) had 8,640,000 inhabitants with a total of 7,339,552 motorcycles and 637,323 automobiles. There are about 2,807 factories releasing air emission, 2,061,957 household and 5,096 restaurants in the city. A comprehensive study is required to evaluate causes of air pollution and the impacts of air pollution level to public health in this city. The aim of this study is to: (i) Application EMISENS model and other tools to calculate air emission in HCMC and (ii) Modelling the Impact of Air Pollution on Public Health in Ho Chi Minh City for Policy Making and Awareness Creation using Machine Learning. The results showed that comprehensive EI and GHG over HCMC in 2019 was conducted in this project by following the top-down and bottom-up approaches and IPCC-2006 methodology. The estimation of the emission of different types of sources including line, point, area, and the biogenic source was conducted. Traffic sources accounted for the largest emissions for almost all pollutants. Motorcycles were the dominant emission source of all pollutants for on-road sources, accounting for 35.3%, 91.4%, 65.4%, 70.4%, 99.4% and 79.9% of the total line sources emissions for NOx, CO, SOx, NMVOC, CH₄ and PM2.5, respectively. Industrial activities contributed the highest emission of PM2.5 about 39.7% of the total of PM2.5 in HCMC in 2019. The area sources accounted for 38.9% of TSP and 23.5% of PM2.5 in HCMC, whereas, others were negligible sources. Biogenic sources, particularly from greenery, agriculture, mangroves, etc. of the HCMC emitted 4.6% of total NMVOC emissions of the whole city. Motorcycles contributed the highest emission of PM2.5 for all single sources of emission in HCMC. For PM2.5, motorbikes contribute 24.5% of HCMC"s total PM2.5 emissions, Households, Textiles, Metal Production, Food, Restaurants, Seaports, Manufacturing Paper respectively is 15.1, 10.0, 9.1, 6.8, 6.7, 5.8 and 3.8, respectively. With SO₂, motorcycles, Thermo-electricity, Seaports, Textile, Cars, Food, Metal production and HDVs contribute 24.6, 20.7, 11.7, 8.6, 6.6, 5.5, 5.0 and 3.8% of total SO₂ emission of HCMC. Study also develop air quality automatically monitoring network and install 6 air quality stations around HCMC, then apply Machine Learning to analysis/extrapolate hourly air quality data for HCMC, then modeling the the Impact of air Pollution on hospital admission in HCMC. The 13 measure to reduce air pollutants should be based on this detailed EI emission.
