Origin and source regions of PM10 in the Eastern Mediterranean atmosphere

Koçak, Mustafa
Kubilay, Nilguen
A set of daily PM10 (n=281) samples collected from April 2001 to April 2002 at a rural site (Erdemli), located on the coast of the Eastern Mediterranean, were analyzed applying Mass Closure (MC), absolute principal factor analysis (APFA) and Positive Matrix Factorization (PMF) to determine source contributions. The results from the three techniques were compared to identify the similarities and differences in the sources and source contributions. Source apportionment analysis indicated that PM10 were mainly originated from natural sources (sea salt +crustal approximate to 60%) whilst secondary aerosols and residual oil burning accounted for approximately 20% and 10% of the total PM10 mass, respectively. Calculations for sulfate showed that on average 8% and 12% of its total concentration were originated from sea salt and biogenic emissions, respectively. However, the contribution by biogenic emissions may reach up to a maximum of similar to 40% in the summer Potential Source Contribution Function (PSCF) analysis for identification of source regions showed that the Saharan desert was the main source area for crustal components. For secondary aerosol components the analysis revealed one source region, (i.e. the south-Eastern Black Sea), whereas for residual oil, Western Europe and the western Balkans areas were found to be the main Source regions.


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.
Distribution and abundance of ctenophores, and their zooplankton food in the Black Sea. I. Pleurobrachia pileus
Mutlu, E; Bingel, F (Springer Science and Business Media LLC, 1999-12-01)
The distribution of Pleurobrachia pileus Muller, 1776 in the Black Sea was determined using plankton samples collected above the anoxic zone (maximum of 200 m) in the winter, spring, and summer of 1991 to 1995; The summer samples were collected in 1991 to 1993 (for a previous) and are included in this paper for comparative purposes. High concentrations of P. pileus were found at the northern edges of anticyclonic eddies along the southern coastal regions. The biomass and abundance of P. pileus increased fro...
Distribution of gelatinous Macrozooplankton in the southern Black sea during 1996 1999
Kıdeyş, Ahmet Erkan (2001-01-01)
In this study, spatial and temporal distributions of three gelatinous macrozooplankton, the scyphozoan Aurelia aurita and the ctenophores Pleurobrachia pileus and Mnemiopsis leidyi, were evaluated using the data obtained from seven southern Black Sea cruises carried out from 1996 to 1999. A comparison of nets used for the sampling of gelatinous macrozooplankton illustrated the superiority of the Hensen net with a larger mesh size (300 mum) over the Nansen net (112 mum). P. pileus was mainly concentrated bel...
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...
Occurrence, distribution and sources of polychlorinated biphenyls at selected industrial sites in Turkey
Gedik, Kadir; İmamoğlu, İpek; Department of Environmental Engineering (2010)
In this study, the occurrence and distribution of polychlorinated biphenyls (PCBs) were investigated via sampling studies conducted around a thermal power plant (Seyitömer, Kütahya), a scrap metal yard (Kızılırmak, Kırıkkale), transformer repair and maintenance facility (Lake Eymir, Ankara), and two organized industrial districts (ızmit and Mersin), and 120 samples composed mainly of sediments were collected from those sites. Total PCBs ranged from not detected to 385 ng/g for all samples. Analysis of sampl...
