Özet:

In order to determine air quality of cities and to prepare clean air action plans, concentrations of air pollutants should be continuously measured and assessed. In 2019, Turkey has started to use the same limit values for particulate matter (PM10) as European Union use (40 µg m-3 yearly and 50 µg m-3 daily). In this study, PM10 concentrations recorded in all air quality monitoring stations (except mobile and test stations) in Turkey in 2019 are evaluated according to the limit values in Turkish air quality regulation. Insufficient data producing stations are removed from the dataset. Geographical Information Systems are used to create limit exceedance maps and PM10 pollution distribution map. Exceedances of limit values for both yearly and daily are determined for 176 stations. As a result, 71 stations satisfied yearly threshold value whereas 105 stations exceeded annual limit. Muş, Iğdır and Kahramanmaraş - Elbistan stations have the highest PM10 values in 2019. Daily PM10 measurements at 145 stations exceeded the regulation limit value. Better air quality is observed near the Sea of Marmara. Muş and Iğdır are the most polluted cities in terms of particulate matter pollution. 49 of 81 provinces of Turkey have inhaled polluted air in terms of particulate pollution in 2019. As a result of the evaluation made according to the station types, it was determined that the annual average limit value was exceeded highest at the traffic stations (72%).
