Determination of ambient levels and sources of volatile organic compounds in İzmir-Aliağa Region

Doğan, Güray
In this study, atmospheric levels and sources of VOCs at Aliağa industrial area was investigated. For this, VOC concentrations were measured at two monitoring stations through winter and summer campaigns in 2005 and 2006. Sampling stations were located in downtown Aliağa and downwind of industrial facilities, approximately 500 m to the south east of Horozgediği village. After the summer sampling, another temporary station was installed in between PETKİM and TÜPRAŞ, named as TÜPRAŞ Station to generate TÜPRAŞ and PETKİM profiles. More than 50 species were measured in all stations. In all stations, toluene has the highest contribution to total VOC concentration. Toluene is followed by m,p-xylene and benzene. While higher concentrations of traffic related VOCs were measured at Aliağa station, VOCs from industrial solvents and industrial processes were higher at Horozgediği station. The concentration levels in Aliağa and Horozgediği are found to be comparable to the other industrial regions reported in the literature. Investigation of episodes, diurnal variations of VOCs and meteorological parameters showed that PETKİM and TÜPRAŞ emissions affect the concentrations levels at Horozgediği and Aliağa stations. Source profiles of PETKİM and TÜPRAŞ are determined by using the TÜPRAŞ station data set. 2-methyl-hexane, benzene and 2,2,3-tri-methyl-butane+2,3-di-methyl-pentane are found to be good markers of PETKİM emissions. Ten different VOC sources were identified in the region. These were gasoline exhaust, diesel exhaust, natural gas use, gasoline evaporation, industrial emissions-1, natural gas construction, non-industrial solvent use, industrial emissions-2, PETKİM emissions, and mixed emissions from PETKİM and shipbreaking facilities.


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...
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...
Spatial and temporal distribution of inorganic and organic pollutant concentrations at Northwestern Anatolia
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...
Ambient VOC concentrations in the city of Balikesir and its environment
Yalçın, Giyasettin Efdal; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2013)
The assessment of volatile organic compounds (VOCs) has become an important field of interest in atmospheric pollution. This study quantifies and characterizes the ambient levels and spatial distribution of VOCs in urban and rural areas of Balıkesir. In addition, for the city drinking water dam excess flux from the traffic estimation was done. For these assessments passive sampling of VOCs performed at approximately 50 locations in and around the city of Balıkesir and analyzed with GC-FID system. Tenax TA w...
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....
