Abstract

Concentrations of ten essentials and non essentialstrace metals Hg, Mg, Fe, Zn, Cu, Ni, Cr, Cd, Pb and Co were determined in the muscles of two squids (Loligoduvauceli; n=24, Sepioteuthislessoniana; n=27) and one cuttlefish (Sepia latimanus; n=12) species collected from Kalpitiya and Mannar area of Sri Lanka in 2010. Trace metals were analysed using Varian Atomic Absorption Spectroscopy (VGA, GTA and Flame AAS). The mean values of all trace metals in muscles of studied species were within the international safety limits and pooled mean concentration of trace elements were following order; Mg > Zn > Cu > Fe > Cr > Ni > Hg > Cd > Co >Pb.
