Abstract: The Northern Key Economic region of Vietnam is a dynamic economic center that is an important economic locomotive of the North and the whole of Vietnam. In this area, large industrial parks are concentrated, attracting many large FDI projects. Key industries: cement production, cars - motorcycles, electronics,... Economic development entails environmental problems. The industrial sector has been identified as the number one driving force driving the growth of Hanoi city and neighboring provinces. Therefore, industrial development is one of the main causes of environmental pollution. In addition, the growth rate of industry in neighboring provinces significantly affects the air quality in Hanoi city. Some factories in Vinh Phuc, Hung Yen, Bac Ninh and Hai Duong provinces have large sources of gas emissions, potentially affecting air quality around Hanoi city. Monitoring results show that air pollution in Hanoi city is mainly caused by dust pollution, especially PM2.5 superfine dust. This is a very harmful dust to health; it is necessary to determine the cause and control solution. Therefore, the objectives of this study are: (1) inventory of potential emissions sources for industrial activities in the northern key economic region around Hanoi; (2) Simulate air spread by AERMOD model to get an overall picture of the industrial impact of surrounding provinces in Hanoi city; (3) Propose solutions to manage air quality for the city in the coming time. Simulation results for pollutants with the highest concentration of NOx for 1 hour , 24 hours and the average of the year is 7.94; 1.02; 0.222 (µg/m3); of CO for 1 hour and 8 hours are 27.616; 8.89 (µg/m3); of SO2 for 1 hour, 24 hours and the average of the year is 4.005; 0.288; 0.038 (µg/m3); of PM2.5 for 1 hour, 24 hours and the average of the year is 0.32; 0.023; 0.003 (µg/m3); of PM10 in 1 hour, 24 hours and year average are 1.03; 0.074; 0.098 (µg/m3).
