Investigating the Air Pollution of Sanandaj whit emphasis on temporal variation of PM10 concentration

This study aimed to examine the relationship between local-regional climatological data and the concentration of suspended particles in Sanandaj. By the use of the index of suspended particles extracted from the DREAM model, the data reported by the weather station in Sanandaj as well as regional climatological data (meteorological data in Middle East) collected through examining various levels of atmospheric synoptic maps and MODIS satellite images, dust transport systems in Kurdistan province were investigated. Correlation analysis between the average monthly temperature and the index of suspended particles revealed that there was a direct correlation between these two parameters so that during this study, the highest amount of suspended particles belonged to May and July. There was also a negative correlation between the average monthly humidity and the index of suspended particles. The overall results of this study indicated that the region has been faced with a drought in recent years. In fact, lack of rainfall and humidity along with seasonal wind patterns in the Middle East, particularly in the warm seasons of the year, have caused the pollution of suspended particles in Sanandaj.
