Essential and Non-Essential Metal Concentrations in Shrimps from Iskenderun Bay, Türkiye

Abstract

Contamination of the aquatic environment and living things with pollutants is increasing day by day. Among these pollutants, heavy metals come to the forefront in terms of toxicological and public health due to their widespread use, toxicity, and resistance to degradation, as well as accumulation and biomagnification in the food chain. The aim of the study is to find essential (Cr, Cu, Fe, Mn, Ni, Zn) and non-essential (As, Al, Cd, Pb) shrimps in Metapenaeus monoceros, Penaeus japonicus, Penaeus semisulcatus (n=30) fished in the Northeastern Mediterranean, Iskenderun Bay was the determination of metal concentrations by ICP-OES. The concentration (ppb) of Cd, Cr, Ni, and Pb were under LOD. The concentration (ppm) ranges were Al: 0.73-38.89, As: 2.18-9.68, Cu: 28.96-69.01, Fe: 7.85-241.36, Mn: 0.44-1.28, and Zn: 51.71-108.51 for all species. Except the As concentrations the differences between mean concentrations of metals in shrimp species were not statistically significant (p
