Objective : To Compare the contents of inorganic elements in squid ink and sepia ink. Methods: Metal elements were determined by AAS.Hg and As were determined by AFS and Ag-DDC, respectively. Results-Calcium was 0. 34% and 1. 07% in sepia and squid ink, which were highest in routine elements in both inks. Fe,Sr and Cu were relative higher in the trace elements. Toxic element, Pb, Cd and As, were higher in sepia than in squid ink by 121%,127% and 319%,while Hg was similar. The total inorganic substance in squid ink was only one third of that in sepia,while organic substance was much greater than in sepia. Conclusion: Besides Fe and Zn,all the other trace elements determined in sepia were greater than those in squid ink. This obvious difference in elements between the two inks maybe not only related with their biological difference, but also with the element levels of oceans they lives.
