Goksu Delta is a specially protected area in the Mediterranean region of Turkey. The delta is classified as a Wetland of International Importance according to the RAMSAR Convention on Wetlands of International Importance. Increases in population have recently taken place in this region due to heavy agricultural activities and discharges of anthropogenic wastes. In the present study, frequencies of erythrocytic nuclear abnormalities such as, micronuclei (MN) and nuclear buds (NB) were investigated in peripheral blood of three fish species; Clarias gariepinus (Catfish), Alburnus orontis (Bleak), and Mugil cephalus (Mullet) from Akgol (AG) and Paradeniz (PD) lagoons of Goksu Delta. Concentrations of heavy metals (Cu, Cd, Ni, Pb) were also measured in the water, sediment samples. MN and NA frequencies were elevated in fish from AG and PD lagoons in comparison with those from upstream regions. The results of this study indicate that the lagoons of Goksu Delta contaminated with genotoxic pollutants and that the genotoxicity is related to the agricultural activities and to the discharge of anthropogenic waste waters.

Evaluation of heavy metal contents, polyaromatic petroleum hydrocarbons and some inorganic pollutants in the south Marmara rivers, Turkey
Yılmaz, Ayşen; Yemenicioglu, S; Aksoy, S; Torunoglu, T (1998-05-01)
Nilufer River is the main receiving body of water for the industrial and domestic wastes of 1.000.000 populated Bursa metropolitan area and it combines with Kocasu River before entering the sea at the south Marmara region, Turkey. Variations in concentrations of Na, K, Ca, Mg, Fe, Cl, SO4, PO4, NH4, NO3, NO2, BOD5, COD, polyaromatic petroleum hydrocarbons (PAH), pH and some heavy metals (Hg, Cd, Cr, Zn, Pb) were seasonally determined in 1991-94 period. The results showed that these rivers are included in th...
Simulation of yacht movements in Göcek Bays
Genç (Numanoğlu), Aslı; Özhan, Erdal; Department of Civil Engineering (2004)
Fethiye-Göcek area is one of the nine coastal Specially Protected Area (SPA) in Turkey. Since mid-80̕s Göcek town has developed to be a yachting center, and the bays of Göcek have acquired a well-earned international fame as a paradise for boating vacations. However, the uncontrolled yachting in this bay area presents a growing pressure on the environment, and the coastal and marine ecosystem. In this thesis a computer model for simulating the movements of yachts in Göcek Bays is developed. The computer mod...
Eutrophication of the Izmit bay, Marmara Sea
MORKOÇ, ENİS; Tuğrul, Süleyman; OKAY, OYA; Legovic, T (1997-04-01)
The elongated Bay of Izmit is one of the most heavily polluted semienclosed basins in Turkey. From systematic data obtained during field studies between 1984 and 1988, it is clear that two distinct water masses are present throughout the year. The brackish water which originated in the Black Sea forms a 10 to 15 m thick surface layer. Its salinity and temperature vary from 22-24 ppt and 20-24 degrees C in summer, to 26 ppt and 7 degrees C, in winter. Marine water, which arrived from the Mediterranean, under...
Evaluation of the best management practices to control agricultural diffuse pollution in lake mogan watershed with swat model
Özcan, Zeynep; Alp, Emre; Kentel Erdoğan, Elçin; Department of Environmental Engineering (2016)
Lake Mogan which is located in Gölbaşı County, Ankara, Turkey is one of the most important wetlands of Turkey and it was declared as Special Environmental Protection Region in 1990. Total area of semi-arid Lake Mogan watershed is 970 km2 and dry farming is practiced approximately in 40% of the basin. Therefore, agricultural diffuse source pollution is a serious concern in the watershed. In the context of this thesis, the effects of implementation of different agricultural best management practices on sedime...
Determination of nutrient loads in Mogan watershed through modelling approach
Özcan, Zeynep; Kentel Erdoğan, Elçin; Alp, Emre (null; 2015-09-12)
Lake Mogan which is located in Gölbaşı County, 20 km south of Ankara, Turkey is one of the most important wetlands of Turkey and it was declared as a Special Environmental Protection Region in 1990 because of its ecological value. Mogan Watershed which has an area of 970 km2 is dominated by agricultural land use. The ecological integrity in Lake Mogan is under threat due to high level of urbanization, industrial and agricultural activities. In this study, unit diffuse pollution loads resulting from differen...
