Plants normally growing on soils in the Northeastern United States contain about 0.05ppM of selenium on a dry weight basis. It has been shown that plants growing on soils amended with coal fly ash or on fly ash alone absorbed notably higher concentrations of selenium. It is well know that certain plant species of the genus Astragalus which grow over a wide area of the Western United States accumulate very high concentrations of the element. Fly ash and some of these western soils contain selenium in the same concentration range. It was of interest therefore to study the availability of this toxic element in fly ash to a selenium accumulator plant. In the work reported, one of the well known Astragalus selenium accumulator species was grown to maturity in pots of soil amended with coal fly ash and then analyzed for total selenium.
