In this study, ionic compositions of 350 aerosol samples collected between April 2006 and May 2008 in a rural area at Northwestern Turkey (Black Sea coast of Turkey) were discussed. Ions accounted for approximately 30% of PM mass. Contributions of secondary aerosol species (NO3-, SO42- and NH4+) were higher than the ions with crustal origin. This indicated that sampling station was under the influence of long range transport because there were no industrial emissions around. Concentrations of ions demonstrated a large variation from day to day. Mann-Whitney W test was applied to compare the medians of summer and winter concentrations of ions. All ions, except for NH4+ and SO42-, showed statistically significant difference between seasons with 95% confidence level.


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 characteristics of atmospheric aerosols in a rural site of northwestern Anatolia
Yenisoy-Karakas, S; Tuncel, Süleyman Gürdal (1997-09-01)
Aerosol samples were collected daily at a rural mountainous site of northwestern Anatolia during September 1993-April 1994. Concentrations of SO42-, NO3-, Cl-, NH4+, Na+, K+, Ca2+ and Mg2+ have been determined. Sulfate made up the 30% analyzed aerosol mass with a 2.14 mu gm(-3) average concentration. Measured concentrations were comparable with other rural area data except Ca2+ which was higher in our station with an average concentration of 1.12 mu gm(-3). Monthly concentrations of major ions fluctuate dep...
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...
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...
Thermal characteristics and kinetics of crude oils and SARA fractions
Kök, Mustafa Verşan (Elsevier BV, 2013-10-10)
In this study, two Turkish crude oils from southeastern part of Turkey and their saturate, aromatic and resin fractions were analyzed by thermogravimetric analysis (TGA). The experiments were performed at three different heating rates (5, 10, 15 degrees C/min) under air atmosphere. Two different reaction regions were observed from thermogravimetry (TG), differential thermogravimetry (DTG) curves due to the oxidative degradation of crude oil components. From TGA curves, it was detected that the heavier fract...
