The assessment of volatile organic compounds (VOCs) has become an area of particular interest in the field of atmospheric pollution due to their adverse health and environmental effects. This study is aimed to identify, quantify and characterize VOC in different urban areas and industrial areas in Bursa. The spatial distribution, seasonal variation as well as health risks assessment of VOC were discussed. Air samples were collected by means of sorbent passive sampling at over 50 sampling points in Bursa and analyzed by GC-thermal desorption. A total of seven weekly measurement periods were completed across the city center from 2005 to 2007. The source of VOC was apportioned with the commonly used receptor model, namely Factor Analysis. Motor vehicles and industrial solvent usage are the most abundant VOC sources to contribute to urban atmosphere in Bursa, 63% and 20%, respectively. The health risks of VOC were also evaluated. The questionnaire was filled out by selected people living in Bursa to obtain time-activity pattern for health risk assessment. Lifetime cancer risks were estimated with the measured VOC data. All the statistical parameters used to represent cancer risks for the selected compounds exceeded the stated level. Benzene had the highest adverse health effect among these compounds according to USEPA (2009) calculation with the mean cancer risk 3x10-4. In addition to intensive field sampling campaigns conducted in Bursa, the VOC measurement were completed for a period of six months to evaluate uptake rate of VOC in Ankara. Uptake rate equations depending on relative humidity and wind speed were developed for 25 VOCs.

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...

Volatile organic compounds (VOC’s) attracted attention as air pollutants due to their health effects, particularly with their potential to induce cancer. The levels and sources of VOCs in Bursa atmosphere, which is one of the most heavily industrialize cities in Turkey, were investigated by measuring C2 – C12 VOCs in two campaigns. Concentrations of 148 VOCs were measured with 60 minute intervals using an on-line gas chromatograph. Data generated in this study is the first extensive and high-resolution data...

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...

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 Balikesir city, Turkey. For these assessments, passive sampling of VOCs performed at approximately 50 locations in and around the city of Balikesir. Twenty-five VOCs were regularly monitored and analyzed with the GC-FID system. The sampling periods were carried out for se...

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....
