Özet
Bu çalışmada; Türkiye'nin Doğu Akdeniz kıyısında yer alan, İskenderun Körfezi'nde üç istasyonda avlanan has kefal (Mugil cephalus) ve çipura'nın (Sparus aurata) üreme organları, deri ve kas dokularında Fe, Cu, Ni, Cr, Pb ve Zn düzeyleri belirlenmiştir. Ağır metal düzeylerinin, istasyonlara, balık türlerine ve doku tiplerine göre değişim gösterdiği saptanmıştır. Genelde has kefal'deki (M. cephalus) metal birikimlerinin çipura'dan (Sparus aurata) daha yüksek olduğu ve bu durumun türlerin beslenme alışkanlıklarının farklılığından kaynaklanabileceği söylenebilir. Has kefal'in kasında en yüksek Cu, Zn, Fe, Pb, Ni ve Cr düzeyleri sırasıyla 1,39,47,25, 66,38, 10,02, 1,34 ve 1,71 ug/g yaş ağırlık ve gonadında 44,50, 269,06, 332,56, 90,97, 9,17 ve 8,68 ug/g yaş ağırlık olarak bulunmuştur. Körfez içindeki diğer iki istasyonla karşılaştırıldığında, iskenderun'un evsel ve endüstriyel atıklarının en az etkisinde kalan körfez ağzındaki istasyonun, körfezin en az kirlenmiş bölgesi olduğu belirlenmiştir.
In this study Fe, Cu, Ni, Cr, Pb and Zn contents were determined in muscle, skin and gonads of two fish species (Mugil cephalus L and Spams aurata L.) caught at three stations in the iskenderun Bay of the Eastern Mediterranean coast of Turkey. Heavy metal concentrations varied significantly depending on the type of the tissue, fish species, and location of stations. Generally, M. cephalus showed higher levels of metal concentrations than S. aurata in two of the stations in the inner bay; which might have resulted from the difference in foraging habits of the two species. Cu, Zn, Fe, Pb, Ni and Cr concentrations were found to be the highest in M. cephalus with 1.39,47.25, 66.38, 10.02,1.34 and 1.71 ug g'1 w. wt. in muscle, and 44.50, 269.06,332.56, 90.97, 9.17 and 8.68 pg g"1 w. wt. in gonads, respectively. The least amount of contamination was found to be at the station in the opening of the bay. This station does not receive significant levels of effluents from the industrial and domestic sources in iskenderun city when compared to the other two stations.
