dc.description.abstract Concentrations of trace metals, viz. mercury (Hg), cadmium (CD), lead (Pb), copper (Cu), zinc (Zn), arsenic (As) and selenium (Se) were monitored in frozen squid (Loligo duvacelii) and cuttlefish (Sepia pharaonis) products. The whole soft parts of cuttlefish and squid often contained high levels of Cd(>2ppm) and As (>1ppm). A high concentration of Cd was always associated with high levels of Cu and Zn in both the molluscs. Hg content was very low and ranged between 50-100 ppb. Pb was present in low concentrations. Liver was found to be the major site of accumulation for Cd, Cu and Zn, in these species. The order of accumulation of the metals, in general was liver> gonad > gills > muscle. Se content often exceeded 3 ppm in the whole soft parts. However a corresponding build up was not found in liver or other organs. en_US
