[Identification and quantitation of selenocompounds in environment and organism].
Identify and quantify of diversity of selenocompounds in environment and organism is necessary to further understand and fairly evaluate the effects of selenium in clinical chemistry, nutrition, toxicity, environment and ecology. For the purpose, many state-of-the-art of analytical techniques are applied with the particular emphasis on the effective isolation, high-sensitively element-selective detection and the identification of the detected selenocompounds. Some practical and recently-developed methods, especially Se speciation by the combination of chromatography with mass spectrography, are here reviewed, which is of benefit to the deep researches on the selenium species in environmental samples and biomaterials.
