In this study the air emission inventory tool is used to calculate the total amount of particulate matter PM10 generated from rice straw burning in the Winter - Spring crop in 2020 in Hanoi city. In the next step the ADMS pollutant diffusion model was used to simulate the possibility of particulate matter transmission caused by the rice straw burning. The results show that with a total amount of tons of PM10 and tons of dispersed into the environment causing local air pollution in the southern area of the city where there is a large cultivated area the rice-yield is high and the amount of straw burned in the field accounts for the majority. To minimize the impact of rice straw burning activities government and local authorities need to be more aggressive in implementing the directive to ban burning straw in the city and provide provide more practical alternatives to farmers.
