    Seasonal investigations were conducted on 640 Cyprinus carpio specimens obtained through commercial fishing at four different stations (Gerger, Sitilce, Hosirge, and Samsat) in the Atatürk Dam Lake. MDA (malondialdehyde) levels were measured in the liver and muscle tissues of male and female fish; the results revealed a significant increase in MDA levels at stations exposed to point-source discharge. This indicates that pollution-induced oxidative stress in fish varies significantly across seasonal and regional scales. Among the stations compared, the lowest MDA values were detected in fish tissues from the Gerger station, while the highest values were recorded at the Sitilce and Hosirge stations. Analysis of SOD, GSH-Px, and GSH values across all stations showed that these parameters fluctuated in correlation with MDA levels thereby maintaining the oxidant-antioxidant balance. This study investigated seasonal and spatial variations in oxidative stress biomarkers in common carp (Cyprinus carpio) collected from four stations in Atatürk Dam Lake. A total of 640 specimens were analyzed for malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and reduced glutathione (GSH) levels in liver and muscle tissues. Results showed that MDA levels were significantly higher in fish collected from Sitilce and Hosirge stations, indicating elevated lipid peroxidation associated with point-source pollution. In contrast, the lowest MDA levels were observed at the reference station, Gerger. Antioxidant enzyme activities (SOD, GSH-Px, and GSH) exhibited tissue-, season-, and site-dependent variations, suggesting adaptive responses to oxidative stress. Overall, the findings demonstrate that anthropogenic pressures in Atatürk Dam Lake significantly alter the oxidant–antioxidant balance in fish, highlighting the usefulness of these biomarkers for environmental monitoring.

    Examination Water Quality of Karkamış Dam Lake

    Tepe, Rıdvan; Kutlu, Banu

    This study was conducted in order to reveal the physico-chemical properties of the Karkamis Dam Lake located within the boundaries of Sanliurfa and Gaziantep, water samples were taken from 5 stations at 4 and 8 m depths between January and December 2015. Temperature, pH, dissolved oxygen, electrical conductivity, ammonium nitrogen, nitrate nitrogen, ortho phosphate, phosphorus, total nitrogen and total phosphorus values of water were measured during the year. The detected values were found as temperature (14.3-21.6°C average: 9.4), pH (8.4-9.1-7.8), dissolved oxygen (9-10-11.8 mg L-1 ), electrical conductivity (251-332-412 ,00S cm-1 ) ammonium nitrogen (0,003-0,069-0,194 mg L-1 ), nitrate nitrogen (1,549-2,292-3,473 mg N L-1 ), nitrite nitrogen (0.001-0.006-0.053 mg L-1), ortho phosphate phosphorus (0.007-0.034-0.076 mg L-1 ), total nitrogen (0.722-1.1514-1.696 mg L-1 ), total phosphorus (0.007-0.016-0.026 mg L-1 ). The Karkamis Dam Lake has a Class I high quality water class according to the Quality Criteria for Inland Water Resources Classification according to the Surface Water Quality Management Regulation.

    2013 yılında Birecik Baraj Gölün de dört farklı noktada mevsimsel olarak yerinde ölçümler yapılmış, yüzey ve farklı derinliklerden su örnekleri alınmıştır. Alınan su örneklerinde fiziksel ve kimyasal parametreler incelenmiştir. Mevsimsel değişimler araştırılarak atık suların ve diğer kaynakların baraj gölü sahasına etkisi araştırılmıştır. Bu çalışmada elde edilen parametrelere ait veriler Su Kirliliği Kontrol Yönetmeliğinde bildirilen kıta içi su kalite standartlarına göre değerlendirildiğinde, genel olarak Birecik Baraj Gölü sularının I. sınıf yani yüksek kaliteli su sınıfında yer aldığı sonucuna varılmıştır. Su Kirliliği Kontrol Yönetmeliğinde I. sınıfa dahil olan suların yalnız dezenfeksiyon ile içme suyu temini, rekreasyonel amaçlar, alabalık üretimi, hayvan üretimi, çiftlik ihtiyacı ve diğer amaçlar için uygun olduğu bulunmuştur.
