摘要: The aim of the study is to assess quality fish imported into Nigeria with samples collected in Zaria. Concentrations cadmium, lead, mercury, iron and nickel (Cd, Pb, Hg, Fe Ni) were determined tissues/organs (skin, muscles, gills, liver, intestine, kidneys, brain bones) Trachurus Murphyi species on basis their import batches across two major fishing origins. Health risks human via dietary intake by assessments hazard quotients (HQ), daily metals (DIM) individual’s health risk index (HRI). Elemental determinations performed AAS microwave digestion method tissues. analysis heavy variations (Post-Hoc) shows there are no significant differences (p Hg > Pb Cd Ni. However, individuals consuming above recommended might be at from ingestion unacceptable concentrations.
