Air is considered one of the most important environmental challenges in different parts of the world ، especially in industrial and densely populated cities ، which can lead to social consequences for the health of humans and other creatures. Particulate matter is one of the main air pollutants due to its adverse effects on local ، regional and global air quality. In recent years ، with the increase in population and the increase in industrial activities in metropolises like Isfahan، suspended particles، especially with an aerodynamic diameter smaller than 2.5 and 10 microns PM2.5 and PM10، have become one of the most important pollutants. This study was conducted in order to monitor suspended particles in indoor environments at different stations in the city of Isfahan at the beginning and end of the week and eva‎luate the health assessment. Sampling was done in summer August and autumn November in 6 different stations residential houses in 5 different places، multistorey parking، educational space، commercial spaces، cultural spaces and traditional markets using a portable environmental dust meter. Sampling was done at the stations of residential houses، girls' high school، parking lot، arcade and City Center and Naqshjahan cinema complex for PM2.5 and PM10 and the number of suspended particles was reported. In the summer season، for houses ، Baharestan station was introduced as the most polluted station during the week، and in the second place was the apartment located in Shiraz Gate، which was placed in the first week. According to Shiraz، on top of the pollutants in the Daruzah area، Azaram High School، which was located in this area، had the same early days as last week compared to last week. In the City Center complex، the cinema hall، indoor theaters and parking lot were sampled and it showed suspended particles in the first week due to the increase in population. The last sampling stations were Naqsh Jahan Square ، which had more suspended particles during the week than other stations due to several reasons ، including market structures، crowding، and the presence of markets. In the autumn season، the highest amount of suspended particles was related to Naqshjehan Square stations and the lowest amount was related to the residential house located on Jayshir Street، Isfahan. These results indicate 73 that the control management of suspended particles and the necessity of planning to reduce the emission of these sources are necessary to maintain the health of the residents of Isfahan city.
