Selenium fractionation and speciation in a wetland system
Article Abstract:
Selenium is a leading contaminant of natural water systems especially lakes and reservoirs. Bioaccumulation of selenium in organisms living in these waters poses serious harm to fish and waterfowl. The movement and toxicity of selenium depend on its oxidation states, which are mediated by microbes. Selenium fractionation studies at a wetland ecosystem separated major selenium species biogeochemical cycling. Selenium is removed from the water as the microbes oxidize selenate to elemental selenium.

Environmental conditions controlling selenium volatilization from a wetland system
Article Abstract:
A study aimed at investigating the rates of selenium volatilization, particularly in wetland systems, is presented. Water samples from Benton Lake, MT are examined to determine their natural selenium volatilization. It was found out that selenium volatilization happened in water, sediment, and wetland plants. It was noted that algae and high-selenium sediment register a higher rate of selenium volatilization than watermilfoil and low-selenium sediment. It is believed that efforts in removing selenium in wetland systems can benefit from natural selenium volatilization process.
