Biological Selenium Removal: Solution To Pollution?

Published on Wednesday, 17 September 2008 05:00 from ScienceDaily

Unsafe levels of selenium, sometimes referred to as an "essential toxin," can be reduced by a microbiological treatment. With this method, microorganisms reduce selenate to the less-toxic elemental selenium, which can potentially be recovered from the process. An estimated 0.5 to 1 billion people worldwide suffer from selenium deficiency, even though many live near areas where levels of selenium have reached toxic levels.
