Is selenium a human health hazard?
No, not in the concentrations present at Smoky Canyon. In fact, selenium is an essential nutrient. The concentrations being measured during monitoring at Smoky Canyon indicates that while selenium is elevated, there is no human health risk. This was confirmed in a study conducted in 2002 by an inter-agency government review. The results of this study can be accessed at: http://giscenter-ims.isu.edu/SISP/Area_Wide_Reports.html.
