    Sakarya River with a length of 824 km is one of the most important lothic ecosystems of Turkey. Sariyar, Gokcekaya and Yenice Dams were constructed on the Sararya River for the purpose of electric supply and utility water for agricultural and fishery activities. In this study, sediment samples were collected from 14 stations selected on areas seasonally (2015-2016). Also, cyprinidae species (Carassius gibelio (Bloch, 1782), Capoeta baliki) (Turan, 21 Kottelat, Ekmekci & Imamoglu 2006) were caught from Dam Lakes and Sakarya River. Cr, Ni, Cu, Zn, Pb levels in sediment samples and in tissues (liver, gill and muscle) of fish were analyzed in samples by Analytic Jena ContrAA 700 (high-resolution continuum source atomic absorption spectrometer). The data observed were evaluated with national and international quality criteria. According to the data in the study results, heavy metal accumulations in the gill and liver of fish were determined higher than muscle. Zn levels in muscle of C. gibelio caught from Yenice Dam Lake were higher than the permissible limit stated by Turkish legislation and FAO. Also, Cr and Ni levels in sediment samples especially during rainy seasons were higher to dry seasons and Cr and Ni levels were detected higher than sediment quality guidelines.

    Boron and Arsenic Levels in Water, Sediment, and Tissues of Carassius Gibelio (Bloch, 1782) in a Dam Lake
    (Hard, 2014) Cicek, Arzu; Kose, Esengul; Emiroglu, Ozgur; Tokatli, Cem; Baskurt, Sercan; Sulun, Sule
    The Seydisuyu River one of the tributaries of Sakarya River which is the third largest river system in Turkey. The Seydisuyu Basin includes one of the most important boron mines in world. Boron sources in the Seydisuyu Basin, fertilizers, and pesticides used in agricultural applications; geological structure of the basin and mining applications are resources important for boron and arsenic. Kunduzlar Dam Lake, which is one of: the most important reservoirs of the Seydisuyu basin, was constructed for the Seyitgazi Plain in 1983. Boron and arsenic values were the two important contaminants determined around the region. B and As levels were determined in water and sediment of Kunduzlar Dam Lake and also B levels were identified in tissues of Carassius gibelio. Water and sediment samples were collected seasonally between 2011-12. Also, muscle, gill, and liver tissues of Carassius gibelio (Bloch, 1782) were examined in spring 2012. Arsenic and boron levels in water were found higher than permissible levels. In all tissues of Carassius gibelio bioaccumulation factors (BAFs) for boron were remarkably high and boron accumulation levels in the muscle were lower than other tissues.

    Sediment Quality Assessment in Porsuk Stream Basin (Turkey) from a Multi-Statistical Perspective
    (Hard, 2018) Kose, Esengul; Emiroglu, Ozgur; Cicek, Arzu; Tokatli, Cem; Baskurt, Sercan; Aksu, Sadi
    Porsuk Stream Basin is a significant aquatic habitat located in the middle of the Aegean and Central Anatolian Regions of Turkey. Similar to may aquatic habitats, it is exposed to intensive agricultural, domestic, and industrial pollution. The aim of this study was to determine the toxic element levels in Porsuk Stream Basin sediment and evaluate the detected data using a multi-statistical technique. For this purpose, sediment samples were collected from 18 stations selected on the basin (three of them located on Porsuk Dam Lake) in summer 2015, and zinc, copper, lead, cadmium, nickel, and chromium accumulations in sediment samples were determined. All the detected data were compared with the consensus-based threshold effect concentrations (TEC), and factor analysis (FA) also was applied to detected data in order to evaluate the contamination grades in the basin. According to detected data, although Cu, Pb, and Cd concentrations were detected below the limit values, Zn, Cr, and Ni concentrations exceeded the limit values in general. According to results of FA, 3 factors - industrial, agricultural, and lead - explained 81.56% of the total variance.

    ZINC AND COPPER BIOACCUMULATION LEVELS IN MUSCLE, GILL AND LIVER TISSUES OF AN ENDEMIC FISH SPECIES (SEYDISUYU STREAM BASIN / ESKISEHIR / TURKEY)
    (Yildiz Technical Univ, 2017) Cicek, Arzu; Tokatli, Cem; Kose, Esengul; Baskurt, Sercan; Ermiroglu, Ozgur
    Seydisuyu Stream, which is one of the most important branches of Sakarya River, is located on the Central Anatolia Region of Turkey. Seydisuyu Stream Basin has a globally important boron mine on its watershed area and the system exposed to an intensive agricultural, domestic and industrial pollution. In the present study, zinc and copper bioaccumulation levels in muscle, gill and liver tissues of Sakarya chub species (Squalius pursakensis (Hanko, 1925)) living in Seydisuyu Stream were investigated. The data obtained were compared with Turkish Food Codex (TGK) and Food and Agriculture Organization (FAO). According to detected data, the highest zinc and copper levels were recorded in gill and liver tissues Sakarya chub species in general and zinc levels recorded in muscle of Sakarya chub species were higher than the limits of TGK and FAO.
