Abstract

In this study PMjq profile of Istanbul atmosphere was investigated. The main scope of this study is to determine the effects of long-range PM10 transport and/or regional PM10 transport to Istanbul. For this purpose PMjQ concentration data of 10 air quality monitoring stations belonging to Istanbul Metropolitan Municipality (IMM) were examined. First of all the effects of local sources on Istanbul's PM10 profile were evaluated in detail. Then long-range PM10 transport events were studied. A new method with the data obtained from all the stations, which are simultaneously examined, has been suggested to differentiate effects of long-range PMjq transport (FRPMT) from effects of local PM10 sources. By using this method, FRPMT driven 96 episodic events were determined over Istanbul atmosphere in 2008. Daily PM10 target value of 50 ftg/m3, which will enter into force 01.01.2009 by national regulation, was frequently exceeded during these episodic events. Three of four, about 74%, of the episodic events were observed in winter and spring seasons. Movements of the air parcels causing episodic events were analyzed by using HYSPFIT model. Back trajectories of air masses reaching Istanbul for each episodic event were calculated by this model runs. Finally, individual evaluations were made for each season of 2008. It was found that long-range PM10 transport showed significant seasonal variations.
