Trace elemental characterization of some food crustacean tissue samples by EDXRF technique
2007
The trace elemental analysis of two species of mud crab and three species of prawn samples from Chilika lagoon, Orissa, India has been carried out by using Energy Dispersive X-ray Fluorescence (EDXRF) technique available at Institute of Physics, Bhubaneswar. Elements namely K, Ca, Mn, Fe, Cu, Zn, Se, Br, Sr and Pb have been measured in the present investigation. The study indicates the effectiveness of the technique in analyzing biological materials like tissue samples and opens a door for easy analysis of seafood items with a easy, fast, sensitive, simultaneous multi-elemental technique with a simple sample preparation procedure without any chemical treatment. Though all the specimens were collected from the same environment of the lagoon the elemental variation might be due to the differential migration pattern and metabolism or other biological factors.
