The relationships between fish size (length and weight) and metal concentrations in the tissues were also investigated using Pearson correlation analysis. Concentrations of Al, Fe, Cu, DOI: 10.2478/oandhs-2021-0020 Mn and Zn were higher than those of other metals Category: Original research paper in all tissue samples from four fish species. Fe and Al concentrations were very high, while the lowest Co, Cd Received: October 20, 2020 and Pb concentrations were determined in the muscle, Accepted: December 1, 2020 liver and gill tissues. The results of Pearson correlation analysis showed that significant relationships between heavy metal concentrations and fish size (length and Erzincan Binali Yıldırım University, Kemah weight) were positive (p < 0.01, p < 0.05), except for a few cases. Furthermore, heavy metal concentrations in Vocational School, Erzincan, Turkey the edible parts (muscle) of the studied fish species did not exceed the maximum acceptable concentrations (MACs) proposed by national and international food standards and were safe within human consumption limits, except for Cr.
