Methods have been developed for the analyses of trace metals in various areas of porcine brains, (temporal, parietal, frontal
cortex, both right and left hemispheres). Determinations were carried out using inductively coupled plasma-mass spectrometry
(ICP-MS) and electrothermal atomic absorption spectrometry (ETAAS). The elements investigated were Li, Mn, Cu, Zn, Cd, Hg,
and Pb by ICP-MS and Cu, Cd, and Mn by ETAAS. For determination by ICP-MS, a method of standard additions calibration coupled
with internal standards was used, and for ETAAS, standard additions calibrations were prepared. The accuracy of all methods
was determined using NIST and IAEA certified reference material.
A small number of pig brains were analyzed by instrumental neutron activation analysis for Cr, Co, Cs, Fe, Rb, Se, Sc, Sb,
and Zn using the comparator method of analysis. Four separate NIST standard reference materials have been used to examine
the validity of the comparator method. 相似文献
