Determination of mercury levels in edible tissues of various fish samples from from sır dam lake

Çalışmada 2002-2003 yıllarında Kahramanmaraş Sır Barajı’nda balıkçılığı yapılan Cyprinus carpio (sazan) (n:20) ve Siluris glanis (yayın) (n:13) örneklerinin kaslarında civa (Hg) analizleri yapılmıştır. Analiz sonuçları μg/g kuru ağırlık olarak verilmiştir. Buna göre civa düzeyleri, sazan örneklerinde 0,03-0,18, yayın örneklerinde 0,16-0,38 μg/g kuru ağırlık şeklindedir. Çalışmada incelenen balık örneklerindeki civa düzeyleri düşük olmasına rağmen bölgede gelecekte endüstri ve tarımın gelişmesine bağlı bir kirlilik olabileceği düşünülmektedir.

Sır barajı’ndaki bazı balık örneklerinin yenilebilen kısımlarımda civa düzeylerinin belirlenmesi

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 μg/g dry weight in carp samples and from 0.16 to 0.38 μg/g dry weight in wels samples. Even though no high levels of Hg were determined in the fish, a possible hazard may occur in the future depending on the agricultural and industrial development in this area.
