Abstract

Background and Aim: Carbon Monoxide (CO) that is a toxic gas often has no warning signs for people who are at risk of this pollutant owing to its colorless, odorless and tasteless nature. This study focused on the spatial distribution of CO using the Interpolation methods in Mashhad city. Material and Methods: In this study, data were collected from 19 stations of Mashhad metropolitan area. Then the inverse weighing intervals, ordinary Kriging, and universal Kriging methods were used. To determine the best spatial distribution, the root mean square error was applied. Finally, the best Interpolation method was selected. Monthly zoning map was prepared using geostatistical technics in Arc GIS during 2017-2018. Results: The results showed that ordinary Kriging was a better method rather than universal Kriging and inverse weighteing methods due to the lees error. By providing monthly zoning map in 2017-2018, it was cleared that in the months of April, May and June, the middle belt of the city, where is from northwest to southeast, was more polluted than other sites. The estern part of the city was more contaminated than other parts in July, August and September. The central part of the urban area was more polluted than other sites in October, November and December months. The western and southwestern parts of the city were more polluted than other ones in December, February and March. Conclusion: Among the metropolitan stations for measuring Air Pollution, southern part of Khayam and Sadaf had highest levels of CO and Khaghani and Elahie were lowest rate. Also, monthly zoning maps indicated that the highest pollution rate in hot season was in the eastern and in cold season was in the western part of the city. However, the amount of CO was less than standard level during 2017-2018.
