Content and health risk assessment of selected elements in commercially available fish and fish products

摘要

Selected elements (Na, K, P, Mg, Fe, Zn, Cr, Ni, Cu, Mn, Pb, Hg) in fish and fish products bought in supermarkets in Krakow were investigated. Contents of elements were analyzed using AMA 254 apparatus for Hg, and ICP-AES method on JY238 ULTRACE apparatus after samples digestion (HNO3+HClO4 3:1) for other elements. Elements' concentrations in six fish species and fish products were within the range of (mg/kg w.m.): 2151-6239 for Na; 855-2500 for K; 49.3-183 for P; 353-531 for Mg; 32.6-61.3 for Fe; 4.01-17.6 for Zn; 7.04-12.9 for Cr; 4.25-7.98 for Ni; 1.30-2.27 for Cu; 0.99-1.51 for Mn; 0.09-0.21 for Pb; and 0.01-0.13 for Hg. Human health risk assessment revealed that total non-carcinogenic risk was low to medium with general decreasing order: tuna salmon herring pollock crab sticks iridescent shark-catfish. The carcinogenic risk was acceptable for adults and unacceptable for children. Carcinogenic risk values for all subpopulations for Pb were decreasingly ordered as follows: tuna salmon herring pollock iridescent shark-catfish crab sticks; and for Cr(VI): tuna salmon herring pollock crab sticks iridescent shark-catfish.
