Proton – induced X – Ray emission (Pixe) Analysis of some sea food from Western Niger Delta, Nigeria

Abstract

Periwinkles and crayfish are among the sea foods widely consumed by the people living in the coastal region of Nigeria. The systematic determination of trace -element concentration in periwinkles and Cray fish samples was done by the PIXE method using a 3.0 MeV proton beam obtained from CERD (OAU, Ile-Ife) ion beam analysis (IBA) facility. The following elements where detected and measured in all the samples Na, Ca, Mg, S, CI, K, Si, Fe, Cu, Zn, Br, Sr, the concentration of the elements varied in the different samples, ranging from few ppm to few percent.

PIXE Analysis of NIST and IAEA Biological Reference Materials

“…In particular, the elemental content of K, Ca, Fe, Cu, Zn, As, Se, Sr were 95-108% relative to certified values for SRM Bovine Liver. Agaja and Obiajunwa [21] validated PIXE technique by analysing the SRM Bovine Liver (1577a) and observed 60-100% of recovery for the elements K, Ca, Mn, Fe, Cu, Zn, Br and Rb whereas in the study of Biswas et al [22], 90-110% of recovery was reported for the same elements. Campbell [23] reported that the elements Fe, Cu, Mn, Zn, Se, Br and Rb were within 91-127 % relative to certified values.…”
