Trace elements in squid determined by coupled Plasma mass spectrometry

Abstract

Trace elements in the edible parts, and in the internal organs of squid collected from Binh Thuan Sea were analvzed, using inductively coupled plasma mass spectrometry (ICP-MS). The analyzed data on squid samples  show the difference  in the concentrations of trace elements in the edible parts and internal organs of squid. The distribution of trace elements including bio-essential elements such as Cu, Zn, Se, Cr and Fe and non-essential elements such as Cd, Ag, Th, U and rare earth elements (REE) in squid samples provided the evidence on the role of the squid on the ocean bioaccumulation and detoxification processes. The accuracy of the method was checked by the analvsis of standard samples and the analyzed results obtained were in good agreement with those in the certified materials. From results obtained, it could be concluded that squid can be used as a bio-indicator for monitoring the marine environment.
