Biogeochemistry of selenium. A review

Popis výsledku v původním jazyce

Selenium levels and speciation in environmental compartments and the dynamics of global Se cycling continue to be a subject of intense interest largely because Se is both an essential element and a toxicant at elevated levels. While Se containing amino acids and proteins are known to be critical for normal metabolic functions in many life forms, selenosis, poisoning due to chronic excessive Se intake, has been associated with neurological impairment. This paper reviews the current understanding of the biogeochemistry of selenium in the natural environment. The factors that affect Se speciation in natural environments are chemical, physical, and biological processes. Several inorganic species of Se (-2, 0, +4, and +6) and organic species (monomethylatedand dimethylated) have been reported in aquatic systems. Both HSeO3 (-) and SeO3 (2-) would be present in natural waters. Under mild oxidizing conditions, HSeO3 (-) and SeO3 (2-) are the major species, while HSe- would be the dominant sp
