Description
Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for manganese. Manganese may be found in over 100 minerals, primarily in the form of oxides, silicates and carbonates. It is also found in coal and crude oil. Manganese is used primarily in making steels and nonferrous alloys. Other uses for manganese and manganese compounds include in the manufacturing of batteries, fertilizers, pesticides and ceramics, as a gasoline additive and as a dietary supplement. Manganese compounds are also used in animal feeds, pharmaceutical products, and wood preservatives and as catalysts.
