TRANSFORMATION OF METAL IONS BY PLANTS

对重金属在环境中的命运的理解是 与理解金属离子的形态有关 环境。重金属离子由非生物和非生物共同转化。 生物过程。重金属的生物去除与转化 细菌、真菌和植物对金属有显著的影响 对环境中金属离子命运的贡献 在评估金属离子的迁移率时要考虑到 在环境中，站点是否适合进行补救，或 正在进行修复的场地的进度。我们建议将其描述为 利用XAS研究植物对重金属离子的转化 用植物组织培养鉴定镍和铬的积累 细胞壁和植物细胞内。

An understanding of the fate of heavy metals in the environment is linked to an understanding of the speciation of metal ions in the environment. Heavy metal ions are transformed by both abiotic and biotic processes. Biological removal and transformation of heavy metals by bacteria, fungi and plants can have a significant contribution to the fate of metal ions in the environment which must be taken into consideration when evaluating the mobility of metal ions in the environment, the suitability of a site for remediation, or the progress of a site undergoing remediation. We propose to characterize the transformation of heavy metal ions by plants using XAS to characterize Ni and Cr accumulation by plant tissue culture, both on the cell wall and within the plant cell.
