Abstract
Contamination of the aquatic environment and living things with pollutants is increasing daily. Among these pollutants, heavy metals come to the forefront regarding 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 study aimed to determine the essential (Cr, Cu, Fe, Mn, Ni, Zn) and non-essential (As, Al, Cd, Pb) metal concentrations by ICP-OES of Metapenaeus monoceros, Penaeus japonicus, Penaeus semisulcatus (n=30) caught from the Northeastern Mediterranean, Iskenderun Bay. The concentration 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 for the As concentrations, the differences between mean concentrations of metals in shrimp species were not statistically significant. When the results of the study are compared with the findings of other studies on shrimps caught from the Iskenderun Bay, it shows that Cd, Cr, Ni, and Pb contamination levels decreased, while Cu, Fe, and Zn contamination levels increased.
