Abstract: 

Air pollution is a major problem in Tehran. Most important agents responsible for the high pollution include carbon monoxide, sulfur dioxide, nitrogen dioxide, hydrocarbons and suspended particles. Determination of quality and quantity of polluting agents is of great importance for sustaining the inhabitants health level. We studied carbon monoxide, one of the most hazardous air-polluting agents, in 22 urban districts of Tehran. The results showed that in average 4.39% of the air in Tehran has a CO concentration of 15-30 ppm. The 12th district with 17.99% and 11th district with 16.43% had the highest pollution of carbon monoxide. 6th and 7th districts had 11.22% and 9.5% respectively. The lowest level of pollution was found in 21st district (0%) and 1st district (0.11%). Variance analysis of districts of Tehran showed that there is a significant relation between mean air pollution of 11th and 12th districts and other districts.
