Özet:
This study was conducted to identify physicochemical features of water of Tatlarin Dam
Lake which located within the boundaries of Avanos-Nevşehir and if water pollution is
intended to reveal the genotoxic effect on aquatic fish. During the study, the water samples were taken monthly periods. The measured data were given as following: for Tatlarin Dam Lake: water temperature 15.5 C, 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 (WPCR) its 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.
