Concentrations of elements and ions measured in aerosol samples collected from March 1992 to the end of December 1993 were investigated to identify source regions affecting chemical composition of aerosols in the eastern Mediterranean atmosphere. Collected samples were analyzed for approximately 40 elements and ions using a combination of atomic absorption spectrometry, instrumental neutron activation analysis, ion chromatography and colorimetry. Statistical techniques, such as enrichment factors and a non-parametric bootstrapped potential source contribution function, were applied on the data set to determine main source types and source regions of anthropogenic particles in the eastern Mediterranean basin. Source regions of two previously defined anthropogenic components, namely a long-range transported component and a local pollution component, were identified. The main source areas for pollutants reaching the eastern Mediterranean basin were determined as southern and western parts of Turkey, central and eastern regions of Ukraine, east of Belarus, Greece, Georgia, Romania, coastal areas along France and Spain and coastal areas around the Black Sea, Russia. More distant source regions in the South of UK and Sweden, the central part of Algeria, the northeastern part of Turkey, Russia, Germany, Hungary, Czech Republic, Bosnia and Herzegovina, and coastal areas of Egypt, Israel and Italy do affect aerosol composition in the eastern Mediterranean, but transport from these regions cannot account for the highest 20% of the measured pollutant concentrations.

Temporal variability of atmospheric trace element concentrations over the eastern Mediterranean Sea GÜLLÜ, GÜLEN; Ölmez, İlhan; Tuncel, Süleyman Gürdal (2000-07-01) Concentrations of elements and ions measured in aerosol samples collected between March 1992 and December 1993 were investigated to understand temporal variability of elemental concentrations. Collected samples were analyzed by atomic absorption spectrometry, instrumental neutron activation analysis, ion chromatography and colorimetry for approximately 40 elements and major ionic species. Concentrations of elements were found to vary greatly on time scales ranging from days to seasons. Short-term variations...
Comparison of sources affecting chemical compositions of aerosol and rainwater at different locations in Turkey Türküm, Ahmet; PEKEY, BEYHAN; PEKEY, HAKAN; Tuncel, Süleyman Gürdal (2008-09-01) In this study, concentrations of elements and ions were measured in atmospheric aerosol and rainwater samples collected at two rural stations on the Mediterranean and Black Sea coasts of Turkey. The relationship between chemical compositions of atmospheric aerosol and rainwater was investigated using receptor-oriented methods utilizing long-term data collected at the Antalya and Amasra stations in Turkey. Factor analysis performed on aerosol and rainwater data sets yielded that source types affecting chemic...
Particulate matter (PM10) in Istanbul: Origin, source areas and potential impact on surrounding regions Koçak, Mustafa; Zarmpas, P.; Im, U.; Bougiatioti, A.; Yenigun, O.; Mihalopoulos, N. (2011-12-01) Water-soluble ions (Cl-, NO3-, SO42-, C2O4-, Na+, NH4+, K+, Mg2+,Ca2+), water soluble organic carbon (WSOC), organic and elemental carbon (OC, EC) and trace metals (Al, Ca, Ti, V. Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb) were measured in aerosol PM10 samples above the megacity of Istanbul between November 2007 and June 2009. Source apportionment analysis using Positive Matrix Factorization (PMF) indicates that approximately 80% of the PM10 is anthropogenic in origin (secondary, refuse incineration, fuel oil and s...
Atmospheric trace element concentrations over the eastern Mediterranean Sea: Factors affecting temporal variability GÜLLÜ, GÜLEN; Olmez, I; Aygun, S; Tuncel, Süleyman Gürdal (1998-09-20) Concentrations of elements and ions were measured in aerosol samples collected between March 1992 and December 1993 at a rural station on the Mediterranean coast of Turkey. Concentrations of pollution-derived elements are lower than corresponding concentrations reported for the western Mediterranean region, due to the longer distances traveled by the particles to reach the eastern Mediterranean region. Concentrations of elements vary on timescales ranging from days to seasons. Short-term variations in the c...
Seasonal variability of optical properties of aerosols in the Eastern Mediterranean Vrekoussis, M; Liakakou, E; Koçak, Mustafa; Kubilay, N; Oikonomou, K; Sciare, J; Mihalopoulos, N (2005-12-01) The aerosol optical properties (scattering and absorption coefficients) were investigated at two remote locations in the Eastern Mediterranean in conjunction with aerosol ion composition measurements: Finokalia in the Crete Island in Greece (March 2001-June 2002) and Erdemli in Turkey (July 1999-June 2000). Ambient light-scattering coefficient (sigma(sp-532 nm)) at Finokalia had a mean value of 50 +/- 23 Mm(-1) while at Erdemli this value was 90 +/- 160 Mm(-1), due to a severe dust event that occurred from ...
