标题：Determination of Cu, Zn and Cd Concentrations of Mullet and Perchs Hunted in Büyük Menderes Delta and Investigation of Their Relationship with Metallothionein
摘要：In our study, liver and muscle samples of 15 pieces mullet and perchs fish samples hunted from Büyük Menderes Delta were solubilised in the microwave and Cu, Zn, Cd analyzes were performed by ICP-OES. Metallothionein levels in fish liver tissues were determined by ELISA method. The highest Cu values were found at perch liver (3485.20±543.80 μg/kg), the highest Zn values were found at mullet liver (522.60±91.46 μg/kg), the highest Cd values were found at perch muscle (9.43±1.26 μg/kg). The metallothionein level in mullet liver is 115.62 ± 571.51 mg/kg and in perch liver is 109.44±159.54 mg/kg. When obtained results are compared to the literature data and related ministry regulations with considering the tolerable limits, it is concluded that mullet and perchs samples hunted from Büyük Menderes Delta do not constitude risk for public health in respect to their heavy metal contamination levels. There was no statistical significance between the levels of heavy metals and metallothionein concentrations in tissues.
