Streszczenie: This study aimed to determine the concentrations of toxic and essential elements in the muscle tissue of 11 common fish species (Black Sea Goby, Sprat, Whiting, M. horse mackerel, Shad, Grey mullet, Bluefish, Turbot, Red mullet, Garlfish, Atlantic Bonito) from the southern Black Sea coast of Bulgaria were determined by Inductively-coupled plasma optic emission spectrometry (ICP-OES). The concentration ranges of toxic metals and essential elements in all samples, based on the overall average, were as follows (mg/kg wet weight): Pb: 0.001- 0.045 mg/kg, Cd: 0.008 – 0.07 mg/kg, Zn: 2.58-10.67 mg/kg, Cu: 0.17-0.58 mg/kg, Fe: 2.5-12.8 mg/kg, Mn: 0.088- 1.52 mg/kg, Cr: 0.006-0.15 mg/kg, Ni: 0.001-0.195 mg/kg, As:0.09-0.84 mg/kg, Hg:0.006-0.14 mg/kg. The metal concentrations in the muscle were below the maximum permissible levels set by international organizations for seafood, except Cd for Sprat and M. horse mackerel. The human risk was assessed by calculating the target hazard quotients (THQ) and hazard index (HI). The target hazard quotient for individual elements and hazard index was lower than 1, indicating no potential risk to humans from fish consumption.
