Evaluation of ozone concentrarion in two metropoitan cities of Iran

摘要

Increasing development of urban communities and increasing of economical and industrial activities nowadays without paying attention to the evaluation of these activities on the human healthiness as the development arbor has been made the air pollution of cities and the dangers resulted from the propagation of various pollutants. This research is performed with comparison of density amount of air ozone of 3 stations in Tehran and Esfahan city with quantitative method by using statistical assumption tests during 2009 to 2010. For reliable obtained results of these tests, numbers of sampling to 100 units increased in different days and hours and then with documentation to central limit theorem (one of the most basic theorems on statistic) has been used from normal distribution rules and application on statistical assumption tests. The obtained results from the evalution showed that in Tehran, Ostandary station, Bakhtiardasht station and Laleh station of Esfahan, the concentration of ozone, is increased during years 2009-2010 also at 2009, the changes of ozone concentration in the station ofLaleh of Esfahan is equal with Shahrerey station of Tehran and in 2010 Bozorgmehr station of Esfahan city due to the similar geographical,urban and traffic situation is equal with Ostandary station of Tehran.
