Читать книгу Selenium Contamination in Water - Группа авторов - Страница 34

The occurrence of Se in the environment is mostly in two forms, i.e. organic and inorganic Se. The organic form includes selenoaminoacids, selenopeptides, and selenoproteins whereas different minerals contain it in the form of selenites and selenates, which are inorganic forms of Se. The inorganic forms are more toxic than organoSe compounds and have less bioavailability. The main classes of organoSe compounds include selenols, diselenides, selenoxides, selenones, Se acids, selenides, Se halides, and selenaheterocyclic compounds (Back 2006).
