Metal-organic acid, metal-amino acid, metal-polysaccharide, metal-protein, metal-deoxyribanucleic acid (DNA), etc. are a series of biometals in environmental and biological samples. The major ligand sites for a metal ion bond in these biometals are oxygen-, sulfur-, nitrogen- and phosphorus-containing functional groups. Metallomics is a new idea to integrate metal speciation of biometals and their biological functions in organism. Heavy metal accumulating and hyperaccumulating plant species are environmental biological resources. Elucidation of metal speciation and its biological functions of biometals in these plants is a new field in metallomics. Research subjects in metallomics and analytical techniques required in the metallomics researches are provided, and the prospective for the metal accumulating and hyperaccumulating plant species is presented.
