In this study, particulate matters (TSP, PM10, PM2.5 and PM10-2.5) which are hazardous for environment and human health were investigated in Erzurum urban atmosphere at a sampling point from February 2005 to February 2006. During sampling, two low volume samplers were used and each sampling period lasted approximately 24 h. In order for detection of representative sampling region and point of Erzurum, Kriging method was applied to the black smoke concentration data for winter seasons. Mass concentrations of TSP, PM10 and PM2.5 of Erzurum urban atmosphere were measured on average, as 129, 31 and 13 mu g/m(3), respectively, in the sampling period. Meteorological factors, such as temperature, wind speed, wind direction and rainfall were typically found to be affecting PMs, especially PM2.5. Air temperature did not seem to be significantly affecting TSP and PM10 mass concentrations, but had a considerably negative induction on PM2.5 mass concentrations. However, combustion sourced PM2.5 was usually diluted from the urban atmosphere by the speed of wind, soil sourced coarse mode particle concentrations (TSP, PM10) were slightly affected by the speed of wind. Rainfall was found to be decreasing concentrations to 48% in all fractions (TSP, PM10, PM10-2.5, PM2.5) and played an important role on dilution of the atmosphere. Fine mode fraction of PM (PM2.5) showed significant daily and seasonal variations on mass concentrations. On the other hand, coarse mode fractions (TSP, PM10 and PM10-2.5) revealed more steady variations. It was observed that fine mode fraction variations were affected by the heating in residences during winter seasons.

ELEMENTAL COMPOSITION OF PM10 AND PM2.5 IN ERZURUM URBAN ATMOSPHERE, TURKEY BAYRAKTAR, Hanefi; Turalioglu, F. Sezer; Tuncel, Süleyman Gürdal; Zararsiz, Abdullah (2011-01-01) This study investigated the elemental concentrations of atmospheric particulate matter (PM10, PM2.5) and their relationships with meteorological factors in Erzurum urban centre, Turkey. The average elemental concentration PM10 values for Ca, Mg, Si, Al, Pb, Zn, Cu and Ni in Erzurum city atmosphere were 2112, 184, 2134, 746, 6, 44, 38 and 2 ng/m(3), respectively, and that of PM2.5 were 103, 30, 717, 86, 4, 6, 70 and 1 ng/m(3), respectively. Furthermore, during the sampling period, whilst on average 90% of so...

Source Identification of Volatile Organic Compounds and Particulate Matters in an Urban and Industrial Areas of Turkey PEKEY, BEYHAN; PEKEY, HAKAN; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal; Arslanbaşı, Demet; BOZKURT, ZEHRA (2015-06-01) Elevated levels of volatile organic compounds (VOCs) and particulate matters have been observed in recent years in Kocaeli, Turkey, despite improvements in pollution prevention technology that have led to a reduction in gas and particulate emissions. Local authorities should devise alternative strategies to reduce the possible health effects of a variety of pollutants that affect air quality. The objective of this study was to identify potential sources of VOCs, fine particulate matter (PM2.5) and coarse pa...
Determination of source apportionment of volatile organic compounds in Ankara Sert, Ezgi; Tuncel, Süleyman Gürdal; Aslan Kılavuz, Seda; Department of Environmental Engineering (2017) In this study, ambient concentrations of fifty-one volatile organic compounds (VOCs) were measured to determine their current level, emission sources and contributions in both urban and suburban atmosphere of Ankara. Two sampling stations were established in Ankara, one in Ankara University (AU), Faculty of Agriculture, other in Middle East Technical University (METU). AU stations is for representing the urban atmosphere while METU represents suburban atmosphere. In these stations with canister sampling, be...
Source Apportionment of Personal Exposure to Fine Particulate Matter and Volatile Organic Compounds using Positive Matrix Factorization PEKEY, HAKAN; PEKEY, BEYHAN; ARSLANBAŞ, DEMET; BOZKURT, ZEHRA; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal (2013-01-01) The objective of this study was to identify potential sources of personal exposure to fine particulate matter (PM2.5), volatile organic compounds (VOCs), NO2, SO2, and O-3 in an urban and industrial area of Turkey between May 2006 and January 2007. Personal exposures were determined once per person in 28 adults over a 24-h period. Energy dispersive Xray fluorescence and a wavelength dispersive X-ray fluorescence spectrometry were used to measure 15 elements in PM2.5, including Al, As, Ca, Cr, Cu, Fe, K, Mn,...
