Kurşun (Pb) derişimlerinin etkisinde Oreochromis niloticus solungaç dokusunda Na+, K+, Ca++ ve Mg++ iyon düzeyleri 10, 20 ve 30 gün sürelerde incelenmiştir. O. niloticus’lar 0.1, 0.5 ve 1.0 mg /L- Pb derişimlerinin etkisinde 10, 20 ve 30 günlük sürelerle solungaç dokularındaki iyon derişimleri (Na+, K+, Ca++ ve Mg++) Atomik Absorbsiyon Spektrofotometrik yöntemle saptanmıştır. Solungaç dokusu iyon (Na+, K+, Ca++ ve Mg++) düzeyleri kurşundan etkilenmiştir. Kurşun ortam derişimleri solungaç dokusu Na+, Ca++ ve Mg++ iyon düzeylerinde bir artışa neden olurken, K+ iyon düzeylerinde bir azalmaya neden olmuştur. Bu çalışmada iyon düzeylerinin kurşundan etkilenmesi nedeniyle O. niloticus’un metal kirliliğine karşı hassas bir organizma olduğu saptanmıştır.

The Effect of Lead on Ion Levels of Oreochromis niloticus Gill Tissue

Öz

Na+, K+, Ca++ and Mg++ ion levels in Oreochromis niloticus gill tissues under influence of lead (Pb) concentrations were investigated for 10, 20 and 30 days. Ion concentrations of O. niloticus gill tissues were determined by Atomic Absorption Spectrophotometric method for 10, 20 and 30 days in concentrations of 0.1, 05 and 1.0 mg LPb. Gill ion (Na+, K+, Ca++ and Mg++) levels were affected by Pb. Lead concentrations caused an increase in Na+, Ca++ and Mg++ ion levels, but caused a decreased in K+ ion levels. In this study, O. niloticus was found to be an organism sensitive to metal contamination due to Pb influences of ion levels.
