Metal levels in Sander lucioperca (Linnaeus, 1758) and their health risk assessment for consumers

Abstract

The current study was conducted to determine the residues of Zn, Fe, Cu, Cd, Hg, Pb, and As in the edible tissues of Sander lucioperca. Total of 20 fish individuals collected from Lake Balık, Samsun were analysed by using ICPMS (Inductively Coupled Plasma Mass Spectrophotometer). All metal values in the muscle of S. lucioperca were quite low. Fe is the highest concentration (4.07 mg/kg), whereas Cd had the lowest Cd (0.007 mg/kg). Therefore, it can be said that the bioaccumulation of metals in pike‐perch did not go over the acceptable limits established for these metals by national and international organisations. The hazard quotients (HQs) for individual elements and the hazard index (HI) were all <1 in S. lucioperca, showing no danger by these chemicals when consumed by infants, children, and adults. The RIs for Pb were between 1.45 × 10−7 and 4.30 × 10−7, indicating their insignificant carcinogenic risks, whereas for As these values were between 2.78 × 10−5 and 1.06 × 10−4, indicating their tolerable or acceptable carcinogenic risks.
