P>This study presents indoor/outdoor PM2.5 and PM10 concentrations measured during winter and summer in 15 homes in Kocaeli, which is one of the most industrialized areas in Turkey. Indoor and outdoor PM2.5 and PM10 mass concentrations and elemental composition were determined using an X-ray fluorescence spectrometer. Quantitative information was obtained on mass concentrations and other characteristics such as seasonal variation, indoor/outdoor (I/O) ratio, PM2.5/PM10 ratio, correlations and sources. Average indoor and outdoor PM2.5 concentrations were 29.8 and 23.5 mu g/m3 for the summer period, and 24.4 and 21.8 mu g/m3 for the winter period, respectively. Average indoor and outdoor PM10 concentrations were 45.5 and 59.9 mu g/m3 for the summer period, and 56.9 and 102.3 mu g/m3 for the winter period, respectively. A varimax rotated factor analysis (FA) was performed separately on indoor and outdoor datasets in an effort to identify possible heavy metal sources of PM2.5 and PM10 particle fractions. FA of outdoor data produced source categories comprising polluted soil, industry, motor vehicles, and fossil fuel combustion for both PM fractions, while source categories determined for indoor data for both PM2.5 and PM10 comprised industry, polluted soil, motor vehicles, and smoking, with an additional source category of cooking activities detected for the PM2.5 fraction.

Vertical variation and source evaluation of VOCs and inorganic pollutants in a university building YURDAKUL, Sema; CİVAN, MİHRİBAN; DOĞAN, GÜRAY; Uzmez, Ozlem Ozden; Gaga, Eftadeo O.; Dogeroglu, Tuncay; Ayakli, Gul; Tuncel, Süleyman Gürdal (2018-01-01) Concentrations of volatile organic compounds (VOCs) and inorganic pollutants including sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O-3) were measured using passive samplers in both indoor and outdoor environments at 2, 5, 8, 13, 17, 24, and 29 m from the ground level at a high-rise building in the Middle East Technical University campus in Ankara, Turkey. The measured indoor concentrations of Sigma 24VOCs were highly variable, ranging from 98g m(-3) (at the ground floor) to 235.3g m(-3) (at the...
ELEMENTAL COMPOSITION OF PM10 AND PM2.5 IN ERZURUM URBAN ATMOSPHERE, TURKEY BAYRAKTAR, Hanefi; Turalioglu, F. Sezer; Tuncel, Süleyman Gürdal; Zararsiz, Abdullah (2011-01-01) This study investigated the elemental concentrations of atmospheric particulate matter (PM10, PM2.5) and their relationships with meteorological factors in Erzurum urban centre, Turkey. The average elemental concentration PM10 values for Ca, Mg, Si, Al, Pb, Zn, Cu and Ni in Erzurum city atmosphere were 2112, 184, 2134, 746, 6, 44, 38 and 2 ng/m(3), respectively, and that of PM2.5 were 103, 30, 717, 86, 4, 6, 70 and 1 ng/m(3), respectively. Furthermore, during the sampling period, whilst on average 90% of so...
Geothermal energy potential and utilization in Turkey Taşdemiroğlu, Ersoy (Elsevier BV, 1988-3) The regional distribution of the geothermal energy potential in Turkey, recent surveys, and utilization areas are described. The present and future roles of geothermal energy and their economic aspects are discussed. The implications of geothermal energy exploration and utilization are noted. Recommendations are made to expand geothermal-energy development.
Air quality impacts of electricity use in domestic heating: A comparative study for Ankara Kayin, S; Yavuzdemir, F (1997-09-26) In this study, existing air quality affects of current domestic heating systems in comparison to the electricity use alternative in Ankara have been analysed. For the winter season 1991-1992 heat energy used in Ankara for domestic heating has been calculated. For the hypothetical case of electricity use instead of the current domestic heating systems in the city, Industrial Source Complex - Short Term dispersion model has been used for six site alternatives and for two different thermal power plant technolo...
Integrated Watershed Management for Lake Mogan with the focus of Agricultural Diffuse Pollution Özcan, Zeynep; Başkan, O; Düzgün, Hafize Şebnem; Kentel, Elçin; Alp, Emre (2015-09-25) Lake Mogan located 20 km south of Ankara, Turkey has a watershed area of 970 km2, and it is dominated by areas with dry agricultural practices (50%) and graze lands (31%). Intense agricultural activities and fast urbanization rates are the most important factors affecting the water quality in Lake Mogan. There has been several management alternatives suggested to improve the water quality in Lake Mogan. In 2008, the municipality implemented lake augmentation strategy to increase the water level since it dro...
