Sources and Wet Deposition Fluxes of Polycyclic Aromatic Hydrocarbons (PAHs) in an Urban Site 1000 Meters High in Central Anatolia (Turkey)

Tuncel, Süleyman Gürdal
Wet-only precipitation samples were collected using an Andersen wet only sampler (Andersen Samplers, Inc., Atlanta, GA, USA), between December 2000 and June 2002, in Ankara, Turkey. Polycyclic aromatic hydrocarbons (PAHs) were first pre-concentrated using solid phase (SPE) and ultrasonic extraction procedures. They were then analyzed using gas chromatography-mass spectrometry (GC-MS). Phenanthrene (Phe), fluoranthene (Flt), benzo (b+k) fluoranthene (B (b+k) F) and pyrene (Pyr) were the major components of Sigma 14PAH concentrations during both winter and summer seasons. Concentrations of PAHs did not show a statistically significant relation with meteorological parameters, such as mixing height, wind speed, and wind direction. However, they showed a strong linear relation with the ventilation coefficient (VC), signifying the importance of local sources on measured PAH concentrations. Concentrations of PAHs in winter season were higher than their corresponding concentrations in summer season due to seasonal variations in meteorology and emissions. Sources of PAHs in rainwater were apportioned using principal component analysis. Three factors with eigenvalues 1.0 were extracted. The two factors that explained the largest fraction of system variance represented coal and gas combustion whereas the third factor represented motor vehicles. Half of the rain events accounted for approximately 90% of the wet deposition fluxes of PAHs, demonstrating the highly episodic nature of wet PAH deposition.


Rain water chemistry in Ankara, Turkey
Tuncel, Süleyman Gürdal (1996-08-01)
Samples of rain water were collected in Ankara for the period between September 1989 and May 1990, by using wet-only sampler. Concentrations of major cations (H+, Na+, K+, Ca2+ and NH4+) and major anions (Cl-, NO3- and SO42-) were determined for the first time in Turkey. The rain water was not acidic owing to high concentrations of alkaline soil particles in the atmosphere. However, the concentrations of acid forming ions, such as SO42- and NO3-, were higher than the concentrations expected in a typical urb...
Sources and source regions effecting the aerosol composition of the Eastern Mediterranean
DOĞAN, GÜRAY; Guellue, G.; Tuncel, Süleyman Gürdal (2008-04-01)
Positive matrix factorization (PMF) was used to deduce the aerosol sources at a rural site on the Mediterranean coast of Turkey, using sample collected between February 1992 and December 1993. Approximately 600 daily aerosol samples were collected and 40 elements and compounds were analyzed by atomic absorption spectrometry, instrumental neutron activation analysis, ion chromatography and colorimetry.
Pah composition of snow samples in Ankara city
GAGA, EFTADE EMİNE; Tuncel, G; Tuncel, Süleyman Gürdal (2004-01-01)
Surface snow samples were collected in different sites of Ankara in the winter of 2002 to investigate their concentrations of Polycyclic Aromatic Hydrocarbons (PAHs). The collected samples were pre-concentrated by Solid Phase Extraction (SPE) and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS). Extraction procedure and analysis parameters were optimized and a sampling apparatus for collection of surface snow samples was developed. Phenanthrene was found to be dominant at all sites examined. The maj...

Bulk aerosol samples were collected using a high volume sampler at a rural site (Erdemli) on the coast of Eastern Mediterranean. The sampling was carried out on a daily basis between April 1 – 30 2015 and July 20 – August 20, 2015, and intermittently before April (n=68). The sampling periods were chosen to reflect the aerosol population such as, Saharan dust dominated, mixed and anthropogenic dominated. In addition to high-volume sampling, wet deposition samples were also collected covering the same period ...
Concentration and chemical composition of PM2.5 and PM10-2.5 in the Northeastern Mediterranean
Kubilay, Nilguen; Koçak, Mustafa; Mihalopoulos, Nikos (2006-09-01)
Two stage aerosol samples (PM10-2.5 and PM2.5) were collected at a rural site (Erdemli) located on the coast of the Northeastern Mediterranean, between April 2001 and April 2002. A total of 581 aerosol samples were analysed for trace elements (Fe, Ti, Mn, Ca, V, Ni, Zn, Cr) and water soluble ions (Na+, NH4+, K+, Mg2+, Ca2+, Cl-, Br-, NO3-, SO42-, C2O42- and MS-). The annual mean PM10 and PM2.5 levels were 36.4 +/- 27.8 mu g m(-3) and 9.7 +/- 5.9, respectively. The highest levels of PM10 were observed during...
