Cıvanın balıkları da içeren sucul organizmalar için tehlikeli bir çevresel kirletici olduğu iyi bilinmektedir. Cıvanın balıklardaki birikimi ve toksik etkileri hem bu organizmaları hem de besin zinciri aracılığıyla diğer canlıların sağlığını olumsuz etkileyeceğinden bu metalin toksik etkilerini azaltacak/önleyecek mekanizmalar ekosistemin sağlıklı işleyişi ve geleceği açısından oldukça önemlidir. Bu nedenle sunulan çalışmada Oreochromis niloticus’un dokularındaki cıva birikimi üzerine selenyum ve zeolitin olası koruyucu etkileri araştırılmıştır. Bu amaçla balıklar 0,01 ve 0,1 mg/L cıva; 0,01 mg/L cıva+0,1 mg/L selenyum, 0,1 mg/L cıva+1,0 mg/L selenyum ve 0,01 mg/L cıva+0,1 g/L zeolit, 0,1 mg/L cıva+1,0 g/L zeolit derişimlerinin etkisine 7 ve 21 gün süreler ile bırakılmış ve solungaç, karaciğer ve kas dokularındaki cıva birikimi belirlenmiştir. İncelenen tüm dokulardaki cıva birikiminin denenen tüm kimyasal gruplarında ortam derişimlerine ve etki sürelerine bağlı olarak arttığı saptanmıştır (P<0,05). Dokulardaki cıva birikiminin cıva+selenyum ve cıva+zeolit karışımlarında cıvanın tek başına etkisine oranla önemli bir şekilde azaldığı belirlemiştir (P<0,05). Araştırmamız selenyum ve zeolitin O. niloticus’un dokularında cıva birikimini önemli düzeylerde azalttığını göstermiştir.

Effects of Selenium and Zeolite on Tissue Mercury Accumulation in Nile Tilapia Oreochromis niloticus (Linnaeus, 1758)

Öz

It is well known that mercury is a dangerous environmental pollutant for aquatic organisms including fish. Since accumulation and toxic effects of mercury in fish will negatively affect both these organisms and the health of other organisms through the food chain, the mechanisms to reduce or prevent the toxic effects of this metal are very important for the healthy functioning and future of the ecosystem. Therefore in the present study, it was investigated and possible protective effects of selenium and zeolite on mercury accumulation in tissues of Oreochromis niloticus. For this purpose fish were exposed to 0.01 and 0.1 mg/L mercury; 0.01 mg/L mercury+0.1 mg/L selenium, 0.1 mg/L mercury+1.0 mg/L selenium and 0.01 mg/L mercury+ 0.1 g/L zeolite, 0.1 mg/L mercury+1.0 g/L zeolite for 7 and 21 days and mercury accumulation in gill, liver and muscle tissues were measured. It was determined mercury accumulation in all examined tissues elevated depending on exposure periods and medium concentrations in all chemical groups tested (P<0.05). Mercury accumulation in tissues significantly reduced in mercury+selenium and mercury+zeolite mixtures than in exposure of mercury alone (P<0.05). Our research showed that selenium and zeolite significantly reduce mercury accumulation in the tissues of O. niloticus.
