The speciation of natural tissues by electrospray-mass spectrometry. II: Bioinduced ligands and environmental contaminants

Speciation analysis of biological materials is an emerging field in modern analytical chemistry. Identification and quantification of elemental species gives information about bioaccumulation, detoxification and toxicological implications. Analytical tools employed for speciation are often hyphenated. Structural information for the identification of an elemental species can be obtained with a mode of molecular specific detection. ES-MS is one of the most popular techniques and this review supplies bibliographical information on its application to speciation of bioinduced ligands and exogenous contaminants in biological tissues. The first part of this review dealt with the speciation of arsenic- and selenium-containing biosynthesized species [1].
