Aims & Backgrounds: The purpose of this study was to evaluate the environmental risk of Tehran's sports spaces and spaces in relation to carbon monoxide pollutants.
Methodology: Initially, the data related to carbon monoxide pollutants were collected and analyzed raw from the Tehran Air Pollution Monitoring Center in the period from the beginning of April 1397 to the beginning of April 1398. Based on Craig's introspection, the corresponding raster was generated and classified. Finally, according to the air quality index table (AQI / PSI), the classification was done and the relevant map was prepared. Through the IO technique in the GIS system, the spatial location layer of the sports complex and the contamination layer of the carbon monoxide contaminant were aligned. William Fine's risk assessment method, based on two different scenarios, was used to determine the level and rank of environmental risk.
Findings: The results showed that the highest and the lowest hourly concentration of carbon monoxide pollutants belonged to Aqdasiyeh (2.39 ppm) and Victory (2.11 ppm), respectively. Most of the clean air belonged to the Aqdasiya station (77 days) and the least to the Victory station (7 days). About 30 percent of the days of the year have "unhealthy" and "unhealthy for sensitive groups". Average hourly and daily concentrations of carbon monoxide pollutants were lower than recommended levels at all stations, indicating that none of the sports complexes in the study area are at risk for hourly concentrations of carbon monoxide pollutants. According to Scenario A, the risk rating is related to the carbon monoxide contaminant 24, which indicates a non-hazardous situation and a "low risk level".
Conclusion: About 12 sports complexes are directly exposed to this pollutant and it is necessary to adopt management strategies to improve the quality of this type of urban land use.
