Abstract :In this study, we investigate the application of peak over threshold (POT)  method on extreme events which usually appears with low frequently but high effects. Daily averages of PM 10 and SO 2 pollutants are measured at 5 permanent monitoring stations in İstanbul (Beşiktaş, Yenibosna, Alibeyköy, Esenler, Aksaray). The SO 2 and PM 10 concentration dataare obtained from İstanbul Municipality through a period from January 2009 to December 2015 . Daily averages of theconcentrations are analyzed by using peaks over threshold methods of extreme value theory and then predicted for the largest concentrations for the following 12 months. We find that POT methods can provide useful information about the occurrence of limit exceedances of air pollution in Istanbul and these models can easily be used to make short term predictions about limit exceedances.As a consequence, we can say that predicting the air pollutant levels of SO 2 and PM 10 will be beneficial for the decision makers which help them to develop advanced policies to control and prevent the air pollution.
