In this study, the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) was applied for investigation of PM10 emission rate from Plasco building fire in Tehran city, capital city of Iran. Using reverse engineering approach the PM10 emission rate of Plasco building fire was estimated. Reverse modeling was determined using the AERMOD model and measured PM10 information at the Tehran Municipality Crisis Headquarters Station. The results indicated that the simulated concentration of PM10 using the AERMOD followed the same increase in value as observations in Tehran Municipality Crisis Headquarters Station did due to the Plasco building fire incident in 19th January, 2017. The modeled maximum ground level concentration of 100 ʽg/m3occurred near to emission source for 1- day PM10 dispersion with emission rate of 80 g/sec at the day of accident. The PM10 concentration did not exceeded the limit set by the Iranian Ambient Air Quality Standard even at the day of accident
