Mezgit Merlangius merlangus ve Barbunya Mullus barbatus Balıklarında Ağır Metal Düzeylerini Etkileyen Faktörler

Bu çalışmada, Doğu Karadeniz’de Türkiye ekonomik öneme sahip en önemli iki demersal balık türü olan barbunya ve mezgit balıklarındaki ağır metal birikim düzeylerinin tespit edilmesi ve metal birikim düzeylerinin balık türü, örnekleme yeri, avlanma dönemi ve boy grubu gibi faktörlerle ilişkilerinin ortaya konulması hedeflenmiştir. Balık kas dokularında krom Cr , mangan Mn , kobalt Co , nikel Ni , bakır Cu , çinko Zn , arsenik As , kadmiyum Cd ve kurşun Pb derişimleri indüktif eşleşmiş plazma kütle spektrometresi ICP-MS ile ölçülmüştür. Barbunya ve mezgit balıklarının kas dokularındaki Co, Zn, As ve Cd birikim düzeyleri farklılığı istatistiksel olarak önemli bulunmuştur P

The Factors Affecting Heavy Metal Levels in the Muscle Tissues of Whiting Merlangius merlangus and Red Mullet Mullus barbatus

This study aims to determine heavy metal accumulation levels in the muscles tissues of two economically most important demersal fish species in the Eastern Black Sea, Turkey, red mullet Mullus barbatus and whiting Merlangius merlangus , and evaluate the effects of fish species, sampling locations, fishing season and size groups on heavy metal accumulation levels. Chromium Cr , manganese Mn , cobalt Co , nickel Ni , copper Cu , zinc Zn , arsenic As , cadmium Cd and lead Pb concentrations in fish muscle samples were measured with Inductively Coupled Plasma Mass Spectrometry ICP-MS . Co, Zn, As and Cd accumulation levels in both species differed significantly P
