Abstract

Bu çalışma Tatlarin Baraj Gölünün fiziko-kimyasal özelliklerini ortaya koymak ve kirliliğin balıklar üzerine genotoksik etkisini ortaya koymak amacıyla yapılmıştır. Çalışma Nisan 2013-Mayıs 2014 tarihleri arasında aylık periyotlarla yürütülmüştür. Ölçümü yapılmış olan fizikokimyasal parametrelere ait yıllık ortalama değerlerden; su sıcaklığı 15,5 °C, çözünmüş oksijen 6,44 mg/L, elektriksel iletkenlik 622,9 µmho/cm, toplam çözünmüş madde 0,519 mg/L (TÇM), tuzluluk 0,40 mg/L, pH 10,67, nitrit 0,77 mg/L, nitrat 1,14 mg/L, amonyak 2,67 mg/L, amonyum 1,54 mg/L, potasyum 17,56 mg/L, sülfat 63,7 mg/L, flor 0,57 mg/L, klor 48,23 mg/L, askıda katı madde (AKM) 44,75 mg/L, sertlik 10,82 mg/L, CaCO3 195,67 mg/L, fosfat 2,96 mg/L, kimyasal oksijen ihtiyacı (KOİ) 74,05 mg/L ve biyolojik oksijen ihtiyacı (BOİ) 12,5 mg/L olarak belirlenmiştir. Çalışma sonunda barajın Su Kirliliği Kontrol Yönetmeliği kirlilik sınıflamasına göre “çok kirli sular” kategorisine yakın olduğu sonucuna varılmıştır. Kirli suya sahip baraj gölünde yaşayan Carassius gibelio ve Carassius auratus’a ait mikronükleus frekansları ile kromozom anomalilerinden tomurcuklu nükleus, çentikli nükleus, loblu nükleus ve binükleus frekansları belirlenmiştir. Barajda yaşayan C. gibelio ve C. auratus türlerinin eritrositlerinde mikronükleus frekansı sırasıyla 6,12±3,61 ve 5,57±2,3 olarak belirlenmiştir. Buna göre su kirliliğinin balıklar üzerinde genotoksik etki gösterdiği sonucuna varılmıştır.

Determination of the Genotoxic Effect of Water Pollution on Carassius gibelio and Carassius auratus by Micronucleus Test in Tatlarin Dam Lake

Abstract

This study was conducted to identify physico-chemical features of water of Tatlarin Dam Lake and if water pollution is intended to reveal the genotoxic effect on aquatic fish. This study carried out from April 2013 to May 2014 by monthly intervals. The measured physicochemical parameters were given as following: for Tatlarin Dam Lake: water temperature 15.5 oC, dissolved oxygen 6.44 mg/L, conductivity 622.9 µmho/cm, total dissolved solution 0.519 mg/L (TDS), salinity 0.40 mg/L, pH 10.67, nitrite 0.77 mg/L, nitrate 1.14 mg/L, ammonia 2.67 mg/L, ammonium 1.54 mg/L, potassium 17.56 mg/L, sulphate 63.7 mg/L, flüorine 0.57 mg/L, chlorine 48.23 mg/L, suspended solids (SS) 44.75 mg/L, hardness 10.82 mg/L, CaCO3 195.67 mg/L, phosphate 2.96 mg/L, chemical oxygen demand (COD) 74.05 mg/L, biological oxygen demand (BOD) 12.5 mg/L. According to the results, it was identified that Tatlarin Dam Lake which, according to the classification of Water Pollution Control Regulation is said to be very close to the polluted waters category. Micronucleus freqency was found to be 6.12±3.61 in C. gibelio and was found to be 5.57±2.34 in C. auratus in Tatlarin Dam Lake. The water pollution in Tatlarin Dam Lake can say that showed genotoxic effects.
