Abstract

Bu çalışma Ekim 2012 ve Temmuz 2013 tarihleri
arasında yapılmış ve Işıklı Gölü'nde yaşayan turna balığı'nın kas, karaciğer ve
solungaçlarındaki bazı ağır metallerin seviyelerinin belirlenmesi
amaçlanmıştır. Cihazımızın çalışma doğruluğunu saptamak amacıyla DORM-3 ve
DOLT-4 standart referans materyallerinden de metal analizi yapılarak, elde
edilen değerler Kanada Ulusal Konseyi tarafından verilen değerlerle
kıyaslanmıştır. Cr dışındaki tüm metaller her mevsimde her dokuda tespit
edilmiştir. Cr'un karaciğerde yaz ve sonbaharda, kaslarda yaz mevsiminde analiz
limitinin altında olduğu tespit edilmiştir. Genel olarak, metallerin en fazla
karaciğerde biriktiği, kaslarda ise en düşük seviyede olduğu belirlenmiştir.
Ağır metal seviyeleri yaz ve kış mevsimlerinde artmış, sonbahar ve ilkbahar
mevsimlerinde azalmıştır. Sonuçların bazıları WHO, EC ve Türk Gıda Koteksi
tarafından verilen limit değerlerin üstünde bulunmuştur. Bu çalışma, gelecekte
tarımın gelişmesine bağlı olarak bu bölgede bir tehlikenin oluşabileceğini göstermektedir.

The Seasonal Variations of Heavy Metal Levels in Muscle, Liver and Gill of Pike (Esox lucius L., 1758) Inhabiting Işıklı Lake (Turkey)

Abstract

This study was carried
out between October 2012 and July 2013 and the aim of the current study is to
investigate to determine levels of some heavy metals in muscle, liver and gills
of pike in Işıklı Lake, Turkey. To determine the accuracy of our device, metal
levels were analyzed in DORM-3 and DOLT -4 standard reference materials, the
resulting values ​​were compared with values ​​given by the National Council of
Canada. Except Cr, all metals were determined in all tissues in all seasons. Cr
was below detection limit in liver in autumn and summer and in muscle in
summer. Generally, higher metal levels were found in liver, while the lowest
were determined in muscle tissue of pike. Heavy metal levels in tissues
increased in summer and winter, but decreased in autumn and spring. Some of the
results were above the limits for fish given by WHO, EC and Turkish Food Codex.
This study shows that a potential danger may occur in this region in the future
depending on the agricultural development.
