Selenium: ADWG Guideline 0.01mg/L. An element and non-metal mainly found in sulphide ores such as pyrite. 50% of selenium used in the world, is for glass production. “Selenium and selenium salts are widespread in the environment. Selenium is released from natural and human-made sources, with the main source being the burning of coal. Selenium is also a by-product of the processing of sulfide ores, chiefly in the copper refining industry. The major use of selenium is in the manufacture of electronic components. It is used in several other industries, and selenium compounds are used in some insecticides, in hair shampoos as an anti-dandruff agent, and as a nutritional feed additive for poultry and livestock.” ADWG 2011
