| Abstract: | The poplar hybrid Populus tremula x
alba was shown to volatilize significant amounts of
selenium. The volatilization rates were 230-fold higher from
selenomethionine compared to selenite, and 1.5-fold higher from selenite
than from selenate. X-ray absorption spectroscopy showed that selenate was
metabolized slowly, but selenite was quickly converted to organic
selenium. |
