title: GC/MS analysis of volatile organic selenium species produced during phytoremediation.
abstract: The use of plants and microorganisms that can naturally volatilize selenium and remove it from the soil or water has been studied with promising results. It has been shown that selenium can be removed from soils by plant uptake and accumulation, plant volatilization, and removal in the rhizosphere. Preliminary studies indicated that Hydrilla verticillata Royle removed selenium by means of phytovolatilization. Therefore, studies were conducted to examine the volatile products produced during phytoremediation of selenium by hydrilla. Samples were obtained and analyzed by GC/MS. Organoselenium compounds found were dimethyl selenide, dimethyl diselenide, and diethyl diselenide.
