Sampling and analysis of gaseous pollutants and related particulate matter in a Mediterranean site: Antalya-Turkey

2001-12-01
Gas phase-pollutants, nitric acid (HNO3), sulfur dioxide (SO2), ammonia (NH3) and particulate matter, were collected simultaneously for six months from the Eastern Mediterranean atmosphere (Kucuk Calticak, Antalya) using a "filter pack" system developed in our laboratory. This system is a combination of chemically treated filters for the collection of gaseous ammonia and sulfur dioxide, and Teflon and nylon filters for the collection of particulate matter and gaseous nitric acid, respectively. After pre-treatment, Teflon, nylon and the treated filters were analyzed by ion chromatography (IC) for major ionic species: SO42-, NO3- and Cl-, and by colorimetry for NH4(+) ion. Comparison of the SRM (Standard Reference Material) results with measured concentrations showed a good precision for the IC analyses: 3%, 1% and 2% for Cl-, NO3- and SO42- ions, respectively. Most of the measured parameters were log-normally distributed. Chloride ion had the highest. (4.30 hg m(-3)) and HNO3 had the lowest (0.42 mug m(-3)) concentrations. Total acidity-in the Eastern Mediterranean is controlled by 47.7% HNO3 and 52.8% by H2SO4. Ammonium, nss-SO42- (non-sea salt sulfate) and NO3- did not show a strong correlation, (r(2)=0.4), which means that ammonia is not the major neutralizing species in the Eastern Mediterranean atmosphere.

Erduran, AS; Tuncel, Süleyman Gürdal (2001-12-17)
The concentrations of sulfur dioxide (SO2), ammonia (NH3) and particulate matter were measured for a 6-month period and the concentration of gas phase nitric acid (HNO3) was measured for a 1-month period in the North-eastern Mediterranean atmosphere (Kucuk Calticak, Antalya) using a 'filter pack' system that was developed and optimised in our laboratory. Among all th gas phase pollutants, HNO3 had the lowest concentration (0.42 mug m(-3)) followed by ammonia. Most of the measured parameters showed variation...
Optimization and field application of a filter pack system for the simultaneous sampling of atmospheric HNO3, NH3 and SO2
Karakas, D; Tuncel, Süleyman Gürdal (1997-06-01)
Optimization and field application of a filter pack system for the simultaneous collection of atmospheric gas-phase HNO3, NH3 and SO2 have been studied. A Teflon prefilter was used to remove particulate matter. Nylon filter, oxalic-acid-treated Whatman 41 filter and sodium-carbonate-treated Whatman 41 filter were used for the collection of HNO3, NH3 and SO2, respectively. For the collection of gas-phase HNO3, nylon filters had better efficiency and capacity as compared to NaCl-impregnated Whatman 41 filters...

Indoor concentrations of 34 volatile organic compounds (VOCs), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O-3) were measured at 32 sampling points in classes, offices and hallways of the Environmental Engineering Department (ENVE) in the Middle East Technical University (METU) in Ankara. Outdoor samples were also collected around the department during the sampling campaigns. Two passive sampling campaigns, one in summer and the other one in winter, were conducted. Indoor concentrations of most ...
Determination of ambient elementel and organic carbon concentrations in urban and suburban atmospheres in ankara: estimation of secondary organic aerosol
Koçak, Ebru; Öztürk, Fatma; Aslan Kılavuz, Seda; İmamoğlu, İpek; Tuncel, Süleyman Gürdal (null; 2017-11-04)
The concentrations of organic carbon (OC), elementel carbon (EC) and secondary organic aerosol (SOA) in atmospheric particles were investigated at two sites in Ankara, Turkey. The results show that, mean values of EC, OC, SOA for urban station are 2.30, 10.44 and 13.59 μg/m3 respectively; the mean values of EC, OC, SOA for the suburban station were recorded as 0.85, 5.40 and 7.49 μg/m3 respectively. The summer and winter values of the EC concentration in the urban station were found to be 2.17, 2.48 μg/m3 ,...
Spatial and temporal distribution of inorganic and organic pollutant concentrations at Northwestern Anatolia
Sarısaltık, Ufuk; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2019)
Concentrations of inorganic pollutants including NO2, SO2, O3 and organic pollutants including benzene, toluene, ethylbenzene, o-xylene and m&p-xylene, which are known as BTEX compounds were measured on a seasonal basis in 13 cities located in the Central and Northern parts of Anatolian Plateau. Cities included in measurements were Ankara, Bartın, Bolu, Çankırı, Düzce, Eskişehir, Karabük, Kastamonu, Kırıkkale, Kırşehir, Kütahya, Yozgat, and Zonguldak. Sampling was performed in four seasonal campaigns in eac...
