Volatilization of Selenium from 'Astragalus' Plants Irrigated with Selenium-Laden Water.

PB90146606

Publication Date	1989
Personal Author	MacDonald, D. J.; Lujan, M. J.; Ary, T. S.
Page Count	10
Abstract	Living plants of Astragalus bisulcatus and Atriplex canescens were irrigated with solutions containing selenium to investigate the plants' ability to selectively remove selenium from selenium-contaminated water. The plants were grown from seed in an indoor environment and harvested for analysis at the end of a typical 7-month growing season. Of the total selenium applied to soil in which the plants were grown, only about 1% was incorporated in plant tissues of Astragalus, but approximately 18% of applied selenium was dissipated into the air from the living plants. Atriplex plants did not absorb or dissipate detectable amounts of selenium.
