摘要

In the present study, skipjack tuna ( Katsuwonus pelamis ) from the Karachi coast between 2006 and 2011 were chosen and analyzed for the Fe, Mn, Cu and Zn levels in the edible dorsal tissues, livers, kidney, gills and gonads. The liver tissues had the highest concentrations of metals (623±103 mg kg-1 for Fe, 49±13 mg kg-1 for Mn, 67±17 mg kg-1 for Cu and 68±21 mg kg-1 for Zn). The muscle maximum concentrations of Fe, Mn, Cu, and Zn were 46±17, 6±2, 7±2 and 7±2 mg kg-1, respectively. The results revealed that Fe concentrations were higher than those of other metals. The values obtained were compared with the international regulation maximal allowable standards in seafood. The current work attested that calculated diurnal and hebdomadal intakes of Fe, Mn, Cu and Zn levels by way of consumption of skipjack tuna were not in excess of the Permissible Tolerable Daily Intake (PTDI) and Provisional Tolerable Weekly Intake (PTWI) values established by FAO/WHO. In conclusion, K. pelamis appears to be useful bioindicator due to their accumulation of the metals and continued sampling and pollution effects on food chain organisms comparatively are required for further investigations.
