Trace element and major ion composition of wet and dry depositon in Ankara Turkey
Kaya, Güven; Tuncel, Süleyman Gürdal (1997-12-01)
Daily, wet-only precipitation samples collected over a two year period were analyzed for SO42-, NO3-, Cl-, NH4+, H+, Ca, Mg, K, Na, Al, Cu, Cd, Cr, Zn, V and Ni. Weekly dry-deposition samples collected on petri-dishes over the same period were analyzed only for major ions. Concentrations of ions and elements in Ankara precipitation are comparable with concentrations reported in literature for other urban areas. However, the wet deposition fluxes are the lowest among literature values, owing to small annual ...
Multielement analysis of iliac crest bone by neutron activation
Aras, NK; Ertaş, Gülay; Korkusuz, F; Olmez, I; Sepici, B; Eksioglu, F; Bode, P (2000-04-01)
Bone samples from iliac crest were obtained from apparently healthy female (n=4) and male (n=8) subjects with ages between 15-50. Cortical and trabecular parts were separated and soft tissues like fat, muscle and blood were removed. Calcium, Mg, Na, Cl, Fe, Zn, Br, Sr, and Cs were determined by instrumental neutron activation analysis and other techniques, and their relations were discussed. Fairly good agreement was obtained with literature data. These values may serve as reference values for subjects from...
Quantifying trace elements in the emitted particulate matter during cooking and health risk assessment
Gorjinezhad, Soudabeh; Kerimray, Aiymgul; Torkmahalleh, Mehdi Amouei; Keles, Melek; ÖZTÜRK, FATMA; Hopke, Philip K. (2017-04-01)
Particulate matter (PM) measurements were conducted during heating corn oil, heating corn oil mixed with the table salt and heating low fat ground beef meat using a PTFE-coated aluminum pan on an electric stove with low ventilation. The main objectives of this study were to measure the size segregated mass concentrations, emission rates, and fluxes of 24 trace elements emitted during heating cooking oil or oil with salt and cooking meat. Health risk assessments were performed based on the resulting exposure...
Source apportionment of trace elements in Ankara
Çelik, İlke; Sanin, Faika Dilek; Department of Environmental Engineering (2014)
In this study, chemical composition of aerosol samples in Ankara is identified through receptor modeling. Within the scope of the study, 24-hr aerosol samples are collected by ‘Stack Filter Unit’ with using Nuclepore filter for 9 months at Middle East Technical University campus as a suburban sampling location. Collected filters are analyzed for fifty-seven major and minor trace elements, between z=3 Li and z = 92 (U) and black carbon. Measured concentrations of fine and coarse fractions are compared with c...
Dağlı, Tugay; Türk, Önder; Department of Scientific Computing (2023-1-25)
In this thesis, edge-based finite element method (FEM) approximations of Maxwell's equations describing the relationship between the space variables and sources along the electromagnetic field are considered. In particular, the lowest-order Nédélec basis functions are implemented to construct the FEM model of the Maxwell source problem, Maxwell eigenvalue problem (EVP), and electromagnetic wave propagation problem. A computational model is constructed to conduct all these problems in the same framework of a...
