Abstract
Elimination of environmental pollution has become today one of the major human concerns. Daily human exposure to pollution, especially urban air pollution endangers human health as well as other creatures in some cities and the problem is more significant in developing countries. Air quality in cities is dependent on weather conditions and the amount of air pollution. Today, air pollution is one of the most complex problems of human society that has left negative effects on the health of many living organisms. In this research, Monthly and annual average concentrations of air pollutants recorded in the stations of Tehran Province Department of Environment during the period of 2012 to 2016 were studied. The results showed that rate of carbon monoxide of 2016 decreased compared to the 2015, while the pollutant ozone in 2016 in most months increased compared to the 2015 and the pollutants nitrogen dioxide and sulfur dioxide increased in 2016 as well. Carbon monoxide rate in 2016 at most stations were less than 2015 and the rate of pollutant ozone in 2016 other than Sohanak station decreased compared to previous years. Regarding the standards of the country this study shows that the average concentrations of pollutants nitrogen dioxide, sulfur dioxide, particulate matter with a diameter less than 10 microns and 2.5 microns in air pollution monitoring stations are higher than the standard.
