英文摘要
Description: The work proposed focuses on the use of macro and micro-
PIXE for the quantitative determination of several elements
simultaneously in environmental and biological samples. Sample
preparation techniques need to be developed to minimize disruption of
cells and migration of metal species during or prior to analysis.
