title: Multielemental analysis of purpleback flying squad using high resolution inductively coupled plasma-mass spectrometry (HR ICP-MS).
abstract: Forty-four elements were analyzed in 21 tissues of purpleback flying squid, Sthenoteuthis oualaniensis, by high resolution inductively coupled plasma-mass spectrometry (HR ICP-MS) and inductively coupled plasma atomic emission spectrophotometry (ICP-AES). Greater concentrations of V, Fe, Co, Ni, Cu, Ag, Cd, Pb, and Bi were found in liver, pancreas, and ink sac than in other tissues. Ink sac concentrated remarkable levels of Ca and Sr in addition to the above-mentioned elements. Several alkalis, alkaline earth, and rare earth elements preferentially accumulated in muscle. Among the hard tissues, accumulation of V and U in beak, Ni, Zn, and Cd in gladius and Cr in skin was prominent. K, Rb, Cs, Pb, Bi and some transition elements (V, Co, Cu, Zn, Ag, Cd) were significantly (p < 0.05) higher in the livers of adult than in juvenile squids. Sodium, alkaline earth, and rare earth elements were higher in the livers of juveniles than in adult squids.
