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 pct was incorporated in plant tissues of astragalus, but approximately 18 pct of applied selenium was dissipated into the air from the living plants. Atriplex plants did not absorb or dissipate detectable amounts of selenium.
