Heavy metal levels in some fish species sold at retail in Elazig

Çalışmada, Elazığ balık pazarında satılan gökkuşağı alabalığı (Oncorhynchus mykiss), sazan (Cyprinus carpio), çipura (Sparus aurata) ve levreklerde (Dicentrarchus labrax) kadmiyum, kurşun, bakır, çinko ve demir düzeyleri belirlenmiştir. Toplam 60 balık örneğinin (her balık türü için 15 örnek) ağır metal düzeyleri atomik absorbsiyon spektrometresi kullanılarak incelendi. Gökkuşağı alabalığı hariç, balık örneklerinin ortalama kadmiyum ve kurşun miktarları Türk Gıda Kodeksi tarafından belirtilen maksimum kabul edilebilir düzeyin üzerinde bulunurken, bakır, çinko ve demir düzeyleri maksimum kabul edilebilir düzeyin altında bulundu. Analiz edilen dört balık türü arasında en yüksek kadmiyum, bakır, çinko ve demir oranı sazan balığında bulunurken, en yüksek kurşun düzeyi levreklerde tespit edildi. Sonuçlarımıza göre, analiz edilen 60 balık örneğinin 50’si (%83.3) insan tüketimine uygun değildi.

Elazığ’da perakende satılan bazı balıklarda ağır metal düzeyleri

In this study, the levels of cadmium, lead, copper, zinc and iron in rainbow trout (Oncorhynchus mykiss), common carp (Cyprinus carpio), gilthead seabream (Sparus aurata) and sea bass (Dicentrarchus labrax) sold in Elazig fish market were determined. A total of 60 fish samples (15 samples for each fish species) were analyzed using atomic absorption spectrometer. Average levels of cadmium and lead in the samples, except rainbow trout, were found higher than the maximum acceptable levels established by Turkish Food Codex while levels of copper, zinc and iron in the samples were below. Among the four types of fish samples analyzed, the highest levels of cadmium, copper, zinc and iron were found in common carp while the highest level of lead was in sea bass. According to our results, 50 of 60 (83.3%) fish samples analyzed were not acceptable for human consumption.
