Determination of Mercury Levels in Edible Tissues of Various Fish Samples from S›r Dam Lake

Mercury (Hg) levels in Cyprinus carpio (carp) (n: 20) and Siluris glanis (wels) (n: 13) from S›r Dam Lake, Kahramanmarafl,were measured during 2002 and 2003. The fish samples were obtained from fishermen. Hg levels ranged from 0.03 to 0.18 ìg/gdry weight in carp samples and from 0.16 to 0.38(mu)g/g dry weight in wels samples. Even though no high levels of Hg weredetermined in the fish, a possible hazard may occur in the future depending on the agricultural and industrial development in thisarea.
