The spatial distribution, degree of pollution and major sources of polychlorinated biphenyls (PCBs) were evaluated in surficial sediments of Ankara Creek, located in the capital of Turkey and serving as one of the tributaries in the third largest watershed in Turkey. Sediment sigma PCB concentrations analyzed on Aroclor and congener basis (seven indicator congeners) range from 5.5 to 777.6ng g1 and 3.7 to 743.3ng g1 dw as Aroclor and congener based concentrations, respectively. High concentrations of sigma PCBs were observed in the samples located at the downstream sections of the Creek, after discharge from Ankara municipal wastewater treatment plant. Using a chemical mass balance receptor model (CMB), major sources of PCBs affecting the sediments were investigated. The CMB model identified Aroclor 1254 and 1260 to be the major PCB sources affecting sediments. The potential sources for the PCBs were briefly discussed in terms of their use in various industrial applications.

Hydrogeological and hydrochemical investigation for below-sea-level quarrying at cement raw material site (Kocaeli-Darica, Turkey) Doyuran, Vedat; Karahanoğlu, Nurkan; Çamur, Mehmet Zeki; Topal, Tamer; Süzen, Mehmet Lütfi; Yesilnacar, Ertan (Informa UK Limited, 2003-01-01) A research has been carried Out to investigate the effects of below sea level mining on the cement raw material quality of a limestone quarry located adjacent to the shoreline near Darica-Kocaeli-Turkey. Field studies involved rock mass characterization through discontinuity surveys performed at the working benches of the quarry as well as on the core samples, monitoring of groundwater levels, performance of water pressure tests, and in-situ hydrochemical measurements. Hydrogeological data suggest that the ...
Distribution of tin in the northeastern Mediterranean Yemeni̇ci̇ğlu, Semal; Saydam, Cemal; Sali̇hoğlu, İlkay (Elsevier BV, 1987) Concentrations of tin, one of the naturally methylated elements, was determined in sea water, sediments and organisms, collected from the Northeastern Mediterranean. A hydride generation technique was employed, in which the tin and methyltin, were converted to their hydrides. The hydrides produced were detected by atomic absorption spectrophotometer. On the average, the inorganic tin content of sea water samples ranged between 1.1–236 ng/1. Although the dominant methyltin species was dimethyltin, all forms ...
Levels, Distribution, and Sources of Polychlorinated Biphenyls in Sediments of Lake Eymir, Turkey Gedik, Kadir; İmamoğlu, İpek (Springer Science and Business Media LLC, 2013-08-01) Little information is available on the occurrence and fate of persistent organic pollutants in lakes of Turkey. The present study was performed as a first step to assess the occurrence, spatial distribution, and potential sources of polychlorinated biphenyls (PCBs) in surface sediments of Lake Eymir located in a special protection area. I 41PCB pound concentrations range from 1.09 to 2.33 ng g(-1) in 62 sediment samples collected from the lake. The spatial homogeneity of the PCBs along the whole lake sugges...
Sediment and water phosphorus characteristics in a pond of spring origin, Sakaryabasi springs basin, Turkey Pulatsü, Serap; Akçora, Akasya; Köksal, Fatma (Springer Science and Business Media LLC, 2003-03-01) The purpose of this study was to determine the changes in concentrations of phosphorus and iron in pondwater and porewater in the littoral zone of Sakaryabasi-Kirkgiz pond in central Turkey. The pond supplies water to the Rainbow Trout Fish Culture and Research Station in four months in which temperatures do not show a strong variation (16degreesC-22degreesC). Concentrations of soluble reactive phosphorus were 4- to 5-fold higher in porewater than in pondwater; thus, diffusion of SRP from porewater to pondw...
Emission characteristics of co-combustion of sewage sludge with olive cake and lignite coal in a circulating fluidized bed Toraman, OY; Topal, H; Bayat, O; Atımtay, Aysel (Informa UK Limited, 2004-01-01) In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800 trim height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and Sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90. 15/85, 20/80) were tried. On-line concentrations of major components (O-2, SO2, CO2, CO, NOx, CmHn) were measured in the flue gas, as well as temperature and pressure distribut...
