Materials and Methods: In this cross-sectional study, spatial and temporal changes in PM2.5 concentrations were evaluated. The concentrations of PM2.5 in 6 stations in Isfahan were measured. Data were analyzed using Excel and SPSS software.
Results: The results of the study showed that PM2.5 concentrations were higher in warm months than in cold months, and also in the early days of the week's PM2.5 concentrations were higher than the weekends. The total average of concentration of PM2.5 in Isfahan was 10.9 ± 29.87 μg/m3. The city of Isfahan was healthy for 296 days and for 70 days, it was in an unhealthy condition. Also, concentration of this pollutant was more in the central parts of Isfahan.
