Abstract:

The increase in energy consumption has made air pollution an important problem in residential areas, especially in cities. The widespread use of natural gas in our country and tendency to use high quality coal have partially prevented the increase of the problem but have not eliminate it. The effect of topographic and climatic factors on air pollution, which is a consequence of human activities, is very important. The topography affects temperature inversion due to the stability of the air and also affects pollution as a factor that directs the wind speed. In this study, sulfur dioxide (SO2) and Particulate Matter (PM10) data electronically downloaded from Air Quality Monitoring Station (37˚ 46' 41'' North-30˚ 32' 51'' East) in Isparta city center were used. These data were compared with the National and European Union upper limit value criteria and the daily data of the months when the limits were exceeded (November-December-January-February-March of 2006-2016) were analyzed using the SPSS 23 program. In the study, temperature inversion values were calculated from the data of High Atmosphere Balloons and the relationship between pollutants was analyzed. Multiple Regression and Pearson Correlation tests were used in the data analyzes. According to the regression analysis, the temperature inversion alone gives 38% control over the PM10 density, the temperature inversion and the wind speed together control 47.7%. On the SO2 density, 14.4% of the wind speed; temperature inversion with wind speed has a 23.9% control. Pearson Correlation test results show that there is a moderate and positive correlation between the SO2 and PM10 concentrations which are important parameters of air pollution and the temperature reversal there is also a weak and negative relationship between wind speed and cloudiness in Isparta province. There has been a downward trend in the concentration of both pollutants in recent years. This is thought to be due to the widespread use of natural gas, the upgrading of fuel quality and the increase in the standard of transport vehicles.
