ANALYSIS OF URBAN TRAFFIC POLLUTION UNDER SUMMER AND WINTER CONDITIONS
Abstract
Urban pollution caused by traffic has become a global issue in recent years. Urban pollution is significantly influenced by weather conditions, and the study examines the impact of meteorological parameters such as temperature, solar radiation, precipitation, atmospheric pressure, and wind speed on the pollution levels of O3, NO, NO2, NOx, and SO2 in summer compared to winter. During summer, the average concentration of O3 is higher than in winter, while the average concentrations of NO2, NO, NOx, which are precursors to ozone formation, are lower than in winter. However, the concentration of SO2 is much higher in summer than in winter. This study indicates that pollution is more pronounced in summer with O3 and SO2. This ozone pollution is primarily due to nitrogen oxides reacting with other chemicals under the influence of solar radiation. The correlation coefficients between O3, NO2, NO, NOx concentrations and meteorological parameters have varied significantly in both seasons. High concentrations of O3 have a strong negative correlation with NO2, NO, and NOx, and a strong positive correlation with solar radiation.
