| Abstract: | Six elements in soil, herbage and animal (sheep) hair from the region around Lasa in Tibet were analysed. The results indicated that the content of copper, iron, zinc, manganese, magnesium in soil, herbage and animal (sheep) hair was not deficient,but the selenium in soil and grass was at the critical level of selenium-deficiency. Selenium content in sheep hair were under the critical level, and it indicated that sheep herd of the region around Lasa was selenium-deficiency. |
