Abstract: Air pollution exhibits a very complex and non-linear behaviour as a result of positive and negative changes in time and space, depending on the meteorology and topographic structure, in the transportation of the emissions released into the receiving environment as a result of the activity of air pollution sources. The aim of the study is to monitor the behaviour of air pollutants over VAN in 2019 through statistical analysis of data, to contribute to increasing air quality. PM10 and SO2 parameters have been observed to have the highest average hourly value of 72.5-25.1 µg / m³, and the lowest value (24.8 µg / m³ at 22:00 hours,11.4 µg / m³ at 16:00 hours) respectively. It can be seen 64% of the measured PM10 data were observed in the range of 0.1-40.7 µg / m³. 80% of the same data is less than 56.4 µg / m³ and 91% of the data has the highest density observed in the range 1.1-82.1 µg / m³. while 77% of the measured SO2 data was observed in the range of 1.5-22.7 µg / m³. 80% of the same data is less than 25.1 µg / m³ and 90% of the data has the highest density in the range of -4.7-37.8 µg / m³. The results also showed Wind plays an effective role in the horizontal transport of pollutants in the atmosphere. If the wind is calm, the polluted air stays where it is, and the precipitation help collapse Pollutants in the atmosphere, Because of this feature, precipitation is described as the cleaner of the atmosphere.
