摘　　要：环境和生物体中含硒化合物尤其是有机含硒化合物种类繁杂,为深入探讨和公证评价硒在临床化学、营养学、毒理学以及环境和生态学等领域中的作用或影响,对其不同含硒化合物化学的鉴定和定量是必要的。为此,现代高效分离、高灵敏度元素选择性检测和结构鉴定技术的选择和应用至关重要。本文对目前环境和生物材料中有机硒定性和定量分析技术资料予以综述和简评,期望对有效地进行环境和生物材料中不同有机硒分析研究能有所帮助。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.
