All about selenium

Found 180 links
Page 1 of 12

The EVISA Link database contains information about all aspects of selenium speciation:
- selenium species determination (analytical methods etc)
- toxicity and biological activity of different selenium species
- distribution and fate of selenium species in the environment
- mobility, bioavailability and bioaccumulation of selenium species
- Research groups and their projects related to the chemical speciation of Se
- Standards, rules and legislation related to selenium

If you are looking for something special, please go to the Link Database that will allow for more specific search.
