Chemical composition of atmospheric particles in the aegean region

Munzur, Başak
Daily aerosol samples were collected at the Çandarlı which is located on Aegean coast of Turkey. A rural site was selected to monitor atmospheric pollution by long range transport. Sampling was performed in both summer and winter seasons, and in total 151 samples were obtained. Concentrations of elements in the samples were measured in order to identify sources and possible source locations of pollutants. Measured concentrations of trace elements at the Çandarlı station were compared with those measured at various sites around the world and, also in Turkey. As a result of comparison, level of pollution at the Aegean Region was found to be lower than the Mediterranean Region and Black Sea Region. Air flow climatology at Çandarlı was investigated in order to determine potential source regions for pollutants. Frequency of air flows from Russia and Western Europe are higher suggesting that emissions from these industrial regions affect the chemical composition of particulate matter. Besides these, it was concluded that contributions from Central and Eastern European countries are significantly high because of frequent air mass transport. Concentrations of elements measured at Çandarlı station were found to show short and seasonal variations. Such variations in concentrations are explained by variations in the source strengths and transport patterns. Positive matrix factorization (PMF) was applied to determine sources of elements and contribution of sources to each element. This analysis revealed 5 sources, two local anthropogenic emissions factor, one soil factor, one sea salt factor and one long range transport factor. Distribution of Potential Source Contribution Function (PSCF) values showed that main sources of SO42- are observed in Bulgaria, Romania, Poland, Ukraine and central part of Aegean region.


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...

Almomani, Idrees; GÜLLÜ, GÜLEN; Ölmez, İlhan; ELER, ÜNAL; Ortel, E; Şirin, Gürol; Tuncel, Süleyman Gürdal (1997-01-01)
Daily aerosol and wet-only precipitation samples were collected, between January 1992 and January 1994 at a permanent station established on the Mediterranean coast of Turkey. Collected aerosol and rain samples were analyzed for major ions and a host of trace elements using a combination of analytical techniques, including ion chromatography, atomic absorbtion spectrometry and instrumental neutron activation analysis. The results have demonstrated;hat concentrations of parameters studied are higher than cor...
Chemical composition of precipitation near an industrial area at Izmir Turkey
Idrees F, Al-Momani; OYavuz, Ataman; Mohammad A, Anwari; TUNCEL, SEMRA; Cevdet, Köse; Tuncel, Süleyman Gürdal (1995-05-01)
Wet and dry deposition samples were collected near an industrial area on the Aegean coast of Turkey. Concentrations of major ions (Cl-, SO4(2-), NO3-, H+, Na+, K+, Ca2+, Mg2+, and NH4+) were determined. The pH of the precipitation, calculated from the volume weighted H+ concentration, was found to be 5.6, indicating extensive neutralization of the acidity in the rain. Neutralization was found to be a local process. The main base responsible for the neutralization of acidity was NH3 from fertilizer used in t...
Ionic composition of lower tropospheric aerosols at a Northeastern Mediterranean site: implications regarding sources and long-range transport
Koçak, Mustafa; Mihalopoulos, N (2004-05-01)
Daily bulk aerosol filter samples were collected at Erdemli (36.6degreesN, 34.3degreesE) on the Mediterranean coast of Turkey for a 4-year period between 1996 and 1999. Concentrations of the water-soluble ions (Cl-, Br-, NO3-, SO42-, C2O42- MSA(-), Na+; NH4+, K+, Mg2+ and Ca2+) were measured in a total of 610 samples. In addition, three-dimensional (3-D), 3-day back trajectories of air masses arriving daily at Erdemli were calculated to determine potential aerosol source regions. The results indicated that ...
Chemical composition of the fine and coarse fraction of aerosols in the northeastern Mediterranean
Koçak, Mustafa; Kubilay, Nilguen (2007-11-01)
Two-stage aerosol samples (PM10-2.5 and PM2.5) were collected at a coastal rural site located in the northeastern Mediterranean, between April 2001 and 2002. A total of 562 aerosol samples were analyzed 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 3 4 4 MS-:methane sulfonate). PM10, crustal elements, sea salt aerosols and NO3- were mainly associated with the coarse mode SO42-, C2O42-; whereas non-sea salt (nss) SO42-,...
