Shipborne samples collected from the Black Sea atmosphere were analysed by instrumental neutron activation analysis, atomic absorption spectrometry and ion chromatography for approximately 40 elements and ions. Concentrations of most of the elements are found to be a factor of two higher in the western part of the Black Sea than corresponding concentrations in the eastern part. Main source regions for anthropogenic elements were in Europe. The WNW, WSW and SSW sectors together account for 70% of observed concentrations of elements. Principal component analysis showed a crustal, a marine and three anthropogenic factors. Two of the anthropogenic factors were the result of long-range transport of particles and the third indicated a local iron and steel industry. Atmospheric fluxes of elements to the Black Sea were calculated using observed concentrations. scavenging ratios and precipitation data and results were compared with riverine fluxes of elements. For crustal elements, riverine fluxes were found to be dominant, but for pollution-derived elements, atmospheric fluxes were comparable to riverine fluxes to the Black Sea.

Stable isotope-based reconstruction of Oligo-Miocene paleoenvironment and paleohydrology of Central Anatolian lake basins (Turkey) Luedecke, Tina; Mikes, Tamas; Rojay, Fuat Bora; Cosca, Michael A.; Mulch, Andreas (The Scientific and Technological Research Council of Turkey, 2013-01-01) Isotope geochemistry of lacustrine carbonate represents a powerful tool to reconstruct paleoclimatic and paleoenvironmental conditions. Here, we present a comprehensive set of long-term oxygen (delta O-18) and carbon (delta C-13) stable isotope records from 5 Chattian to Burdigalian lacustrine sequences distributed over the Central Anatolian Plateau. Field relationships combined with stable isotope geochemistry indicate a relatively humid subtropic Late Oligocene climate with an environment characterized by...
2 toxicants, mercury and tin in the Gulf of Iskenderun Salihoğlu, Barış; Yemeni̇ci̇og̈lu, Semal (Elsevier BV, 1987) The concentrations of total mercury and tin in the sediment samples collected from İskenderun bay were determined by utilizing atomic absorption spectrophotometer. Mercury concentration of the samples was determined by cold vapor, and tin concentration by hydride generation techniques. The highest mercury concentrations were measured infront of İSDEMİR (Iron and stell complex) with a value of 550 μg/g (dry weight). The mercury concentrations were found to decrease with distance from the shore. Sediment samp...
Effect of watershed partitioning on hydrologic parameters and estimation of hydrograph of an ungauged basin: a case study in Gokirmak and Kocanaz, Turkey Kocyigit, Musteyde Baduna; Akay, Huseyin; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2017-08-01) The main goal of this study is to investigate the effect of the size of the subbasins of a watershed on the hydrologic parameters and their spatial variability in an estimation of the hydrologic parameters and hydrograph of a neighbouring ungauged basin. In this paper, Hydrologic Engineering Center-Hydrologic Modelling System (HEC-HMS), a semi-distributed hydrologic model, is used to calibrate and cross-validate two flood events occurred in 1998 and then validate four other flood events occurred in 1991, 19...
THE IMPACT OF TOPOGRAPHY ON ISOTOPES IN PRECIPITATION ACROSS THE CENTRAL ANATOLIAN PLATEAU (TURKEY) Schemmel, Fabian; Mikes, Tamas; Rojay, Fuat Bora; Mulch, Andreas (American Journal of Science (AJS), 2013-02-01) Paleoelevation reconstructions of mountain belts and orogenic plateaus based on stable isotope climate and precipitation records benefit greatly from present-day calibrations that relate the fractionation of hydrogen (delta D) and oxygen (delta O-18) isotopes in precipitation to orographic rainfall. Here, we establish a first-order template of delta D and delta O-18 of modern meteoric waters across the Central Anatolian Plateau (CAP) and its bordering Pontic and Taurus Mountains. We identify key regions in ...
PHYTATE CONTENT OF TAIWANESE DIET DETERMINED BY P-31 FOURIER-TRANSFORM NUCLEAR-MAGNETIC-RESONANCE SPECTROSCOPY WANG, CF; TSAY, SM; LEE, CY; LIU, SM; ARAS, NK (American Chemical Society (ACS), 1992-06-01) Phytate and trace element concentrations of the total daily diet of upper social groups in Taiwan were determined by P-31 FT NMR spectroscopy and by instrumental neutron activation analysis, respectively. Results of 15 samples are 2.21 +/- 0.71 g of phytate/kg of dry diet with the range 1.07-3.76 g/kg. The molar ratios of phytate to Zn and Ca were calculated, and bioavailabilities of these elements are discussed.
