    Assessment of Heavy Metal Contamination in Various Tissues of Six Ray Species from A°skenderun Bay, Northeastern Mediterranean Sea
    (Springer, 2013) Turkmen, Mustafa; Tepe, Yalcin; Turkmen, Aysun; Sangun, M. Kemal; Ates, Alpaslan; Genc, Ercument
    This study was performed to investigate the heavy metal concentrations in muscle, liver, gill and intestine of six ray species from A degrees skenderun Bay. The present study is the first for rays in A degrees skenderun Bay, providing valuable preliminary information about heavy metal contents in different tissues of the examined ray species from the bay, and indirectly, indicating the environmental contamination of A degrees skenderun Bay. Heavy metal levels in intestines were generally higher than those in other tissues for all species. Metal levels in ray muscle tissue were below the international maximum allowable levels for fish and fishery products, as well as Turkish national guidelines, with the exception of the highest value for Cd in Dasyatis pastinaca.

    Assessment of Heavy Metals in Fourteen Marine Fish Species of Four Turkish Seas
    (Natl Inst Science Communication-Niscair, 2015) Ates, Alpaslan; Turkmen, Mustafa; Tepe, Yalcin
    Heavy metal concentrations of Cd, Co, Cr, Cu, Fe, Mn, Pb, Ni and Zn in muscles and livers of fourteen fish species from seven stations of four Turkish Seas viz. Mediterranean, Aegean, Marmara and Black Sea, were monitored. Metal concentrations in muscles of fish species were found <0.01-0.43 mg kg(-1) for cadmium, <0.01-0.41 mg kg(-1) for cobalt, 0.03-2.08 mg kg(-1) for chromium, 0.16-10.7 mg kg(-1) for copper, 5.31-115 mg kg(-1) for iron, 0.07-3.62 mg kg(-1) for manganese, 0.01-3.43 mg kg(-1) for nickel, 0.15-1.15 mg kg(-1) for lead, 4.17-22.4 mg kg(-1) for zinc, respectively. All metal concentrations in livers were higher than those of in muscles for the same species. Metal concentrations in the edible parts of fish were assessed for human consumption by comparison with Provisional Tolerable Weekly Intake (PTWI) and Provisional Tolerable Daily Intake (PTDI) values. The values of all metals in muscles of analyzed fish in the present study stayed below the established limit values. Consequently, it might be concluded that these metals in the edible parts of the examined species should not pose any public health problems.

    Determination of metals in fish species from Aegean and Mediterranean seas
    (Elsevier Sci Ltd, 2009) Turkmen, Mustafa; Turkmen, Aysun; Tepe, Yalcin; Tore, Yalcin; Ates, Alpaslan
    Determination of metal levels in muscles and livers of twelve fish species from Aegean Sea and Mediterranean Sea by ICP-AES was made. The levels of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn in muscles of fish were <0.01-0.39, <0.01-0.45, 0.07-1.48, 0.51-7.05, 9.18-136, 0.18-2.78, 0.03-1.72, 0.21-1.28 and 3.51-53.5 mg kg(-1), respectively. Metal levels in muscles were generally lower than those in livers. Metal concentrations in the edible parts of fish were assessed for human uses according to provisional tolerable weekly intake (PTWI) and provisional tolerable daily intake (PTDI). The estimated values of all metals in muscles of fish in this study were below the established values. Therefore, it can be concluded that these metals in edible parts of the examined species should pose no health problems for consumers. (C) 2008 Elsevier Ltd. All rights reserved.

    Some physico-chemical properties of lake Karagol(Erzin-Hatay)
    (Ege Univ, Fac Fisheries, 2006) Tepe, Yalcin; Ates, Alpaslan; Mutlu, Ekrem; Tore, Yalcin
    In this study, it is aim to determine the water quality characteristics of Karagol, located in Gokdere plain of Erzin, Hatay. Karagol, Which is a natural lake and feed by rain and snow, has a total area of 0,15 km(2), and altitude of 273 m. The study was started May 2003, water quality paramaters of pH, dissolved oxygen, temperature, salinity, Chemical oxygen demand (COD), total alkalinity and hardness, ammonia, nitr, te, nitrate, phosphate, sulphate, sulphite, chloride, potassium, sodium, silica were measured monthly for 12 months. According to measured data current water quality characteristics and their monthly variation has determined. Decrease water temperature during the winter months by merging the snow water into the lake and at the same time increased oxygen concentration, similar alkalinity and hardness values through the year has clearly been noticed. As a result, it is concluded that the lake water is not suitable for trout culture but is suitable for warmwater fish culture such as tilapia and carp.

    Water quality of Hasan stream (Erzin-Hatay) and its montly variations
    (Ege Univ, Fac Fisheries, 2006) Tepe, Yalcin; Ates, Alpaslan; Mutlu, Ekrem; Tore, Yalgin
    In the present study, some water quality parameters of Hasan Creek, which source from city of Osmaniye, flow through dense woody area and merge into Iskenderun Bay from Dortyol, Hatay, were investigated. The creek supplies the drinking water of Dortyol and Payas towns. Starting from May 2003 and sampling the water monthly for a year, water quality parameters of pH, dissolved oxygen, temperature, salinity, Chemical Oxygen Demand (COD), total alkalinity and hardness, ammonia, nitrite, nitrate, phosphate, sulphite, sulphate, chloride, potassium, sodium, silica and total dissolved solids were measured in the present study. According to measured study results, changes in water quality parameters of Hasan Creek respect to the months were determined. Measured water quality parameters indicated that the creek water is suitable for the culture of cold-water fish such as trout.
