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.

说明：拟议的工作侧重于使用宏观和微观的 PIXE法定量测定多种元素 同时在环境和生物样品中。样品 需要开发制备技术，以尽量减少对 在分析期间或分析之前，细胞和金属物质的迁移。
