| Research Abstract |
Monochromatic high-energy X-rays (30-37 keV) focused into a microbeam (ca.1 μm) with a Kirkpatrick-Baez mirror allows us for the first time to reveal the striking sub-cellular distribution and the chemical form of cadmium in the cadmium accumulating plant by detecting the Cd Kα line. Micro X-ray fluorescence analysis (μ-XRF) and micro X-ray absorption near-edge structure analysis (μ-XANES) were used for the nondestructive analysis of the Cd distribution and chemical form of Cd at a cellular level in the plant in order to investigate the Cd accumulation mechanism.
