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 a maximum somewhere between 9: 00 to 11: 00 am. Then concentration decreased, until the evening rush hour, owing to increasing mixing height during day time. Then concentrations of BTX increased in the afternoon rush hour which extended to 08: 00 pm. BTX concentrations remained low throughout the night. High binary correlations between BTX compounds suggest a common source, which are traffic emissions. However, other non-traffic sources were also found to be effective, for benzene in the November to March campaign.

The levels and sources of VOCs in the atmosphere of Bursa have been investigated by measuring C-2 - C-12 VOCs which include alkanes, alkenes, alkines, aromatics and halogenated hydrocarbons in two different campaigns. The first campaign was carried out between September 14 and November 6, 2005, and the second one between March 17 and May 10, 2006. The concentrations of 112 VOCs were detected in the collected samples. The median total concentrations of VOCs were 115 and 86 mu g m(-3) for the first and second...

Sarısaltık, Ufuk; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2019)
Concentrations of inorganic pollutants including NO2, SO2, O3 and organic pollutants including benzene, toluene, ethylbenzene, o-xylene and m&p-xylene, which are known as BTEX compounds were measured on a seasonal basis in 13 cities located in the Central and Northern parts of Anatolian Plateau. Cities included in measurements were Ankara, Bartın, Bolu, Çankırı, Düzce, Eskişehir, Karabük, Kastamonu, Kırıkkale, Kırşehir, Kütahya, Yozgat, and Zonguldak. Sampling was performed in four seasonal campaigns in eac...

Concentrations of volatile organic compounds (VOCs) and inorganic pollutants including sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O-3) were measured using passive samplers in both indoor and outdoor environments at 2, 5, 8, 13, 17, 24, and 29 m from the ground level at a high-rise building in the Middle East Technical University campus in Ankara, Turkey. The measured indoor concentrations of Sigma 24VOCs were highly variable, ranging from 98g m(-3) (at the ground floor) to 235.3g m(-3) (at the...

Ambient concentrations of volatile organic compounds (VOCs), nitrogen dioxide (NO2), sulphur dioxide (SO2) and ground-level ozone (O-3) were measured at 55 locations around a densely populated industrial zone, hosting a petrochemical complex (Petkim), a petroleum refinery (Tupras), ship-dismantling facilities, several iron and steel plants, and a gas-fired power plant. Five passive sampling campaigns were performed covering summer and winter seasons of 2005 and 2007. Elevated concentrations of VOCs, NO2 and...
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....
