Trace element composition of atmospheric particles collected at a high altitude site on the Eastern Black Sea coast of Turkey was investigated to understand atmospheric transport of pollutants to this semi-closed basin. Aerosol samples were collected at a timber-storage area, which is operated by the General Directorate of Forestry. The site is situated at a rural area and is approximately 50 km to the Black Sea coast and 200 km to the Georgia border of Turkey. Coarse (PM2.5-10) and fine (PM2.5) aerosol samples were collected between 2011 and 2013 using a "stacked filter unit". Collected samples were shipped to the Middle East Technical University in Ankara, where Na, Mg, Al, Si, S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Ba, Pb were measured by Energy dispersive x-ray fluorescence technique (EDXRF). Comparison of measured concentrations of elements with corresponding data generated at other parts of Turkey demonstrated that concentrations of pollution derived elements are higher at Eastern Black Sea than their corresponding concentrations measured at other parts of Turkey, which is attributed to frequent transport of pollutants from north wind sector. Positive matric factorization revealed four factors including three anthropogenic and a crustal factor. Southeastern parts of Turkey, Georgia and Black Sea coast of Ukraine were identified as source regions affecting composition of particles at our site, using trajectory statistics, namely "potential source contribution function" (PSCF).

Size distribution of trace elements and major ions in the eastern Mediterranean atmosphere Kuloglu, E; Tuncel, Süleyman Gürdal (2005-10-01) Size distribution of trace elements is measured at the Mediterranean coast of Turkey, by analyzing hi-vol impactor samples collected between August 1993 and May 1994. Mass median diameters of marine elements are between 4.6 and 5.3 mu m, and those of crustal elements are between 3.0 and 3.5 mu m. Mass median diameters of crustal elements are 30% smaller in samples impacted by Saharan Dust. Pollution derived elements, As, Cd, Mo, Pb, Se, and Zn have MMD's between 1.25 and 1.01 mu m. Although 70-90% of the ma...
Composition of atmosphere at the Central Anatolia Yörük, Ebru; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2004) Concentrations of elements and ions measured in samples collected between February 1993 and December 2000 at a rural site in central Anatolia were investigated to evaluate the chemical composition of atmosphere at central Anatolia, to determine pollution level of the region, to study temporal variability of the pollutants and to investigate the sources and source regions of air pollutants in the region. Level of pollution at central Anatolia was found to be lower than the pollution level at other European c...
Trace metal composition of particulate matter of the Danube River and Turkish rivers draining into the Black Sea Yigiterhan, Oguz; Murray, James W. (2008-08-16) We determined the composition of particles from several rivers entering the Black Sea as part of a broader study of the composition of suspended matter and sediments in the Black Sea. Suspended matter and surface sediment samples were collected from the Danube River draining from Europe and from four Turkish rivers (Sakarya, Yenice (Filyos), Kizilirmak and Yesilirmak Rivers) in Anatolia. All samples were digested and analyzed by inductively coupled plasma-mass spectrometry and atomic absorption spectrometry...
Seasonal chemical and mineralogical variability of atmospheric particles in the coastal region of the Northeast Mediterranean Kubilay, NN; Saydam, AC; Yemenicioglu, S; Kelling, G; Kapur, S; Karaman, C; Akca, E (1997-02-01) A time-serial analysis of atmospheric particles collected since 1990 at a coastal site bordering the northeastern Mediterranean Sea shows that the collected samples display seasonal patterns in both concentration and color. The 1990-91 and 1992 collections yield an annualised average of around 0.5 g/day dust loading reducing to around 0.3 g/day when the sea-salt contribution is excluded. The highest concentrations of atmospheric particles of continental origin for both natural (e.g. Fe, Mn) and anthropogeni...
SIMILARITIES AND DIFFERENCES IN COMPOSITIONS OF EASTERN AND WESTERN BLACK SEA AEROSOL Balcılar, İlker; ZARARSIZ, ABDULLAH; KALAYCI, YAKUP; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal (2017-01-01) In this study daily aerosol samples were collected at two different sampling stations at the Black Sea Region of Turkey. Western Black Sea sampling station is located at the Bulgarian border of Turkey and approximately 50 km from the Black Sea coast. The station on the Eastern Black Sea is located at a high altitude site which is approximately 75 km from the Black Sea coast. Both stations are situated at relatively remote rural locations. Nearest large settlement area is at least 50 km away from both sites....
