EVALUATION OF THE MAJOR AIR POLLUTANTS LEVELS AND ITS INTERACTIONS WITH METEOROLOGICAL PARAMETERS IN ANKARA

The aim of this study is to examine levels, temporal changes and interactions major air pollutants with meteorological variables in Ankara, Turkey. level namely PM10, PM2.5, SO2, NO, NO2, NOX, O3, CO was evaluated monthly, seasonally, annually during 2019. statistical relationship between ambient temperature, relative humidity pressure examined discussed. concentrations started rise the morning evening hours (excluding O3) when traffic at its peak highest 10:00 -14:00 22:00-02:00. It seen lowest values daylight hours. A strong positive correlation reported PM10 both PM2.5 CO. Also, it NO NOX. On other hand, negative O3 all parameters. Moreover, paired comparisons selected parameters seasons were investigated. statistically significant difference found different CO/NOX, SO2/NOX PM2.5/PM10. results revealed that mentioned has a impact on behavior pollutant
