Assessment of pollution in Ataturk Dam Lake (Adiyaman, Turkey) using several biochemical parameters in common carp, Cyprinus carpio L.

ABSTRACT

Ataturk Dam Lake, the largest impounded lake in Turkey, has been contaminated by domestic, industrial and agricultural effluents coming from Adiyaman city. In this study, we investigated the possible effects of pollutants on several biochemical parameters in the cyprinid fish, Cyprinus carpio, by comparing the parameters in fish collected from a polluted area (Sitilce) to a relatively clean area (Samsat) in August 2011. The activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and lactate dehydrogenase and levels of cortisol, glucose, and K increased while total protein, cholesterol, Ca, Na and Cl levels decreased in fish from the Sitilce site when compared to the Samsat site. The observed alterations in these biochemical parameters indicate that the Ataturk Dam Lake is affected by untreated wastewater discharges.
