Discovered in 1817 as a byproduct of sulfuric acid production, Selenium is a non-metal, chemically related to Sulfur and Tellurium. Prior to the discovery of silicon semiconductors, Selenium was an essential material in the drums of laser printers and copiers. Currently it is used primarily in glass manufacturing and pigments.
Although toxic in large doses, selenium is an essential micro-nutrient in our diets, contributing to thyroid function and a healthy immune system. Selenium is an antioxidant found in the highest levels in Brazil nuts, tuna, crab and lobster.
Recent research has proven that high concentrations of Selenium in salt water, neutralizes the negative effects of Mercury in ocean fish, making it safe for human consumption. This fact inspired the underwater imagery and the “safe fish”.
