Rain water chemistry in Ankara, Turkey

Samples of rain water were collected in Ankara for the period between September 1989 and May 1990, by using wet-only sampler. Concentrations of major cations (H+, Na+, K+, Ca2+ and NH4+) and major anions (Cl-, NO3- and SO42-) were determined for the first time in Turkey. The rain water was not acidic owing to high concentrations of alkaline soil particles in the atmosphere. However, the concentrations of acid forming ions, such as SO42- and NO3-, were higher than the concentrations expected in a typical urban atmosphere. Most of the SO42- in rain water was in the form of CaSO4. Rain-aerosol coupling were examined by simultaneous sampling of aerosols with rain. The ions most efficiently scavenged from the atmosphere were found to be SO42- and Ca2+. (C) 1996 Elsevier Science Ltd


Chemical composition of precipitation at different parts of Turkey
Ayaklı, Gül; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2014)
In this study major ion composition of rain water samples collected at General Directorate of Meteorology Antalya, Balıkesir and Trabzon rain sampling stations were analyzed. The major ions SO42-, NO3-, NH4+, Cl-, Ca2+, K+ and Na+ were analyzed by ion chromatography. Data generated in these stations are compared to evaluate how chemical composition of rainwater changes as air masses travel on the Anatolian plateau. Data also demonstrate how rainwater composition varies seasonally at different parts of Turke...
Chemical composition of rainwater at EMEP station in Ankara, Turkey
Topcu, S; Incecik, S; Atımtay, Aysel (2002-11-01)
The chemical characteristics of rainfall and its seasonal variation at the EMEP (The Cooperative Programme for Monitoring and Evaluation of the Long-Range Transmission of Air Pollutants in Europe) station located in Cubuk, Ankara were studied for the period between September 1994 and December 1996. The station is located in a rural area about 50 km north of Ankara and is considered as a background station for air pollution. The rainwater samples collected were analyzed for pH, major ions concentrations and ...
Sources and Wet Deposition Fluxes of Polycyclic Aromatic Hydrocarbons (PAHs) in an Urban Site 1000 Meters High in Central Anatolia (Turkey)
GAGA, EFTADE EMİNE; Tuncel, Süleyman Gürdal; TUNCEL, SEMRA (2009-01-01)
Wet-only precipitation samples were collected using an Andersen wet only sampler (Andersen Samplers, Inc., Atlanta, GA, USA), between December 2000 and June 2002, in Ankara, Turkey. Polycyclic aromatic hydrocarbons (PAHs) were first pre-concentrated using solid phase (SPE) and ultrasonic extraction procedures. They were then analyzed using gas chromatography-mass spectrometry (GC-MS). Phenanthrene (Phe), fluoranthene (Flt), benzo (b+k) fluoranthene (B (b+k) F) and pyrene (Pyr) were the major components of S...
Chemical composition of Eastern Mediterranean aerosol and precipitation: Indications of long-range transport
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...
Ionic composition of precipitation at the Central Anatolia Turkey
Tuncer, Burcu; Bayar, Banu; Canan, Yeşilyurt; Tuncel, Süleyman Gürdal (2001-12-01)
Concentrations of major ions, SO42-, NO3-, Cl-, H+, Ca2+, K+, Mg2+, Ca2+ and conductivity were measured in approximately 300 daily, wet-only rain samples collected at a permanent rural station between 1993 and 1998. Concentrations of anthropogenic ions NH4+, SO42- and NO3- were among the highest values reported in whole EMEP network, suggesting that the Anatolian plateau is under strong influence of distant emission sources. Although transport of pollutants have significant influence on the chemical composi...
