investigation of temporal variations of pm10 concentration and influence of meteorological parameters on it during 2005-2010

one of atmospheric phenomena of dry and semi-dry areas and areas adjacent to these areas is the phenomenon of dust and production of particulate matter (pm10) that have a lot of environmental hazards. in this research, the purpose is investigation of temporal variations of pm10 concentration during 2005-2010 and influence of meteorological parameters on it. meteorology information have obtained from april 2005 to august 2010 at synoptic station in kermanshah and also, pm10 samples were collected from april 2005 to august 2010 at air quality monitoring station in kermanshah. then, data have analyzed using excel and spss software. the results of monthly variations of pm10 concentration show that july and january months have minimum and maximum pm10 concentration, respectively. highest pm10 concentration have been related to april 2009 to april 2010. also, the results indicate that the relationship of relative humidity, precipitation and percentage of calm wind with pm10 concentration are inverse and the relationship of temperature, percentage of prevailing wind and velocity of prevailing wind with pm10 concentration are direct. therefore, it can been concluded that meteorological parameters have effected pm10 concentration.
