摘要：In recent years, atmospheric models, such as GIS, are used for environmental analysis and the related management for supporting the environmental decision makers in different countries. In this study, concentrations of PM₁₀, PM_2.5 and PM_1.0 are found in urban areas of Tehran in warm and cold seasons and the data applied in the related modelling, using Arc-GIS. For this purpose, samples were collected from 42 sites in an 18 km₂ region located in the west and central parts of Tehran. The mean concentrations of PM_1.0, PM_2.5 and PM₁₀ are found to be 13.14 μg/m³, 22.67 μg/m³ and 95.72 μg/m³ in the warm season; and 50.12 μg/m³, 70.72 μg/m³ and 193.86 μg/m³ in the cold season respectively. In this paper, with the aid of GIS, concentrations of the suspended particles were measured in 22 major hospitals, the patients in which are in contact with these pollutants. It was found the concentrations of the suspended particles were much higher in the cold season
