Daily aerosol samples (PM) were collected at a rural station, which is 5 km away from the Turkish-Bulgarian border between April 2006 and March 2008. Aerosol samples were analyzed for elements by ICPMS, ions by IC and black carbon by aethalometer to provide a multi-species aerosol data set, which can represent aerosol population for Northwestern Turkey and Eastern Europe. Average concentration of SO42-, NO3- and NH4+ was 5.8, 2.9 and 2.0 μg m-3, respectively, while total aerosol mass was 66 μg m-3. Seasonal variation of crustal species had maxima in summer, while most of the anthropogenic species had maxima in winter. Rainfall was found as the only local meteorological parameter affecting aerosols concentrations. The dominant sectors of air masses arriving the Northwestern Turkey were northeast in summer and west-northwest in winter. Air masses were classified into five clusters regarding their wind speed and direction. Most species indicated significant differences between clusters. The influence of forest fires in Ukraine and Russian Federation was identified by cluster analysis using soluble K as tracer. Source apportionment of PM was carried out by EPA PMF model and five sources were resolved. Crustal emissions were found to be the major contributor to PM (41%). The second largest source was distant anthropogenic sources with a contribution of 26%. Traffic was also a remarkable source with 16% contribution. Sea salt and stationary combustion sources accounted for 9% and 8% of PM, respectively. Potential source regions of resolved sources were determined by potential source contribution function (PSCF).

Chemical composition of atmospheric particles as a tool to identify sources affecting aerosol population in the Eastern Black sea atmosphere Balcılar, İlker; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2018) Daily size distributed particulate matter samples were collected at a rural station on Eastern Black Sea region between March 2011 and December 2013. Particulate matter samples were analyzed for trace elements by ICP-MS and ED-XRF and for black carbon by Aethalometer. Mean concentrations of trace elements in the fine fraction varied between 0.0011 ng m-3 for Tm and 1382.42 ng m-3 for SO42-, while mean concentrations in the coarse fraction varied between 0.0017 ng m-3 for Tm and 1441.5 ng m-3 for Si.

Regional and temporal variations in CO2/He-3, He-3/He-4 and delta C-13 along the North Anatolian Fault Zone, Turkey De Leeuw, G. A. M.; Hilton, D. R.; Güleç, Nilgün Türkan; Mutlu, H. (Elsevier BV, 2010-04-01) New He and C relative abundance, isotope and concentration results from nine geothermal locations situated along an 800-km transect of the North Anatolian Fault Zone (NAFZ), Turkey, that were monitored during the period November 2001-November 2004, are reported. The geothermal waters were collected every 3-6 months to study possible links between temporal geochemical variations and seismic activity along the NAFZ. At the nine sample locations, the He isotope ratios range from 0.24 to 2.3R(A), delta C-13 val...
Contributions of natural sources to high PM10 and PM2.5 events in the eastern Mediterranean Koçak, Mustafa; Kubilay, Nilgun (2007-06-01) In total 562 daily PM10 and PM2.5 samples were collected from April 2001 to April 2002 at a rural site (Erdemli) located on the coast of the Eastern Mediterranean. The annual mean PM10 and PM2.5 levels were 36.4 +/- 27.8 and 9.7 +/- 5.9 mu g m(-3), respectively. PM10 and PW2.5 concentrations indicated orders of magnitude change from day to day (PM10 = 2-326 mu g m(-3); PM2.5 = 0.5-28 mu g m(-3)). The highest levels of PM10 were observed during the transition period (March, April and May) due to mineral dust...
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...
Investigation of short and long term trends in the eastern mediterranean aerosol composition Öztürk, Fatma; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2009) Approximately 2000 daily aerosol samples were collected at Antalya (30°3430.54” E, 36°47’30.54”N) on the Mediterranean coast of Turkey between 1993 and 2001. High volume PM10 sampler was used for the collection of samples on Whatman41 filters. Collected samples were analyzed by a combination of analytical techniques. Energy Dispersive X-Ray Fluorescence (EDXRF) and Inductively Coupled Plasma Mass Spectrometry (ICPMS) was used to measure trace element content of the collected samples from Li to U. Major ions...
