A total of 34volatile organic compounds (VOCs) were measured in the indoor of laboratories, offices and classrooms of the Chemical Engineering Department of Hacettepe University in Ankara in 2week-day passive sampling campaigns. The average concentrations ranged from 0.77 to 265g m(-3) at the different indoor sites, with the most abundant VOC found to be toluene (119.6g m(-3)), followed by styrene (21.24g m(-3)), 2-ethyltoluene (17.11g m(-3)), n-hexane (10.21g m(-3)) and benzene (9.42g m(-3)). According to the factor analysis, the evaporation of solvents used in the laboratories was found to be the dominant source.


Source apportionment of volatile organic compounds in Ankara atmosphere
Uzunpınar, Elif Sena; İmamoğlu, İpek; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2015)
In this study, ambient concentrations of volatile organic compounds (VOCs) of Photochemical Assessment Monitoring Stations (PAMS) in Ankara atmosphere were measured to determine the current level and sources of these compounds. Sampling was performed at METU Department of Environmental Engineering from January, 2014 to December, 2014 with stainless-steel canisters. Mean VOC concentrations ranged between 0.04 μg m-3 (cis-2-pentene) and 10.30 μg m-3 (toluene) with average benzene concentration of 1.49 μg m-3....
Source Apportionment of Ambient Volatile Organic Compounds in Bursa, a Heavily Industrialized City in Turkey
CİVAN, MİHRİBAN; Kuntasal, Oznur Oguz; Tuncel, Süleyman Gürdal (2011-01-01)
Weekly passive sampling campaigns were carried out over two sample periods to measure volatile organic compounds (VOCs) in Bursa, one of the most heavily industrialized cities in Turkey. The measurements, taken at 40 points in October 2005 and 49 points in April 2006, revealed concentrations of 34 VOCs, including aromatics, olefins, paraffin and halogenated compounds; with benzene, toluene, ethylbenzene, and o, m, and p-xylene polymers (BTEX) being the most abundant compounds detected at all sample points. ...
Sources of volatile organic compounds at urban and rural Kütahya atmosphere
Bek, Tuğçe; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2015)
This study is a part of a fairly extensive study to investigate contributions of the two thermal power plants, Tunçbilek and Seyitömer, on air quality at Kütahya atmosphere. VOCs were measured at two sampling stations, one was established in the down-town of Kütahya and the other one in the Northeast of the Kütahya. Samples were collected using canisters and they were analyzed using GC-FID system. Average concentrations of VOCs varied between 0.12 g/m3 and 23 g/m3 at urban station and 0.06 g/m3 and 33 g...
Temporal variations of BTX compounds in Bursa/Turkey atmosphere
Yurdakul, Sema; CİVAN, MİHRİBAN; Kuntasal, Oznur Oguz; Tuncel, Süleyman Gürdal (2013-01-01)
Ambient concentrations of C2-C12 volatile organic compounds (VOCs) were measured at Bursa, which is the fourth largest city of Turkey. Two measurement campaigns were carried out between September 14 to November 6, 2005 and March 17 to May 10, 2006. Fifty one VOCs were regularly determined in each chromatogram. However, only BTX compounds are discussed in this study. Concentrations of BTX compounds showed well-defined diurnal cycles. Concentrations increased starting at 06: 00 am in the morning, reaching to ...

Indoor concentrations of 34 volatile organic compounds (VOCs), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O-3) were measured at 32 sampling points in classes, offices and hallways of the Environmental Engineering Department (ENVE) in the Middle East Technical University (METU) in Ankara. Outdoor samples were also collected around the department during the sampling campaigns. Two passive sampling campaigns, one in summer and the other one in winter, were conducted. Indoor concentrations of most ...
