Information on daily concentration of air pollutants, including five pollutants SO2, CO, O3, NO2 and PM10 and Validated according to the World Health Criteria. And in the next step Raw data from air pollutants related to each station Using equation and table standard Converts to separate AQI values for each pollutant And the pollutant having the highest index It was introduced as a pollutant responsible for the day.The data analyzes were used by Excel 2007 and R (3.4.3) software. The significant level was considered to be less than 0.05. According to measurements of air pollutants, 349 days in 245 days, the standard air quality index (AQI <100) and 104 days a year above the standard standard (AQI> 100) were observed In 86 days, from 104 days PM10 and CO emissions as pollutants was responsible for introducing. Given that in 104 days of the year, air quality has exceeded the standard In the days when air quality exceeds the standard, children and elderly take caution
