Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems.
The music video starts with a warning by a voice saying, "In everyday life, there is more than meets the eye. To reach the depths of truth, we must drag the waters." This song is the first single released from the album, and the only one to have a music video. The video was directed by Darrell. [2]
Reports also mention such sources as contaminated drinking water, [11] and fuel additive methylcyclopentadienyl manganese tricarbonyl (MMT), [12] which on combustion becomes partially converted into manganese phosphates and sulfate that go airborne with the exhaust, [13] [14] [15] and manganese ethylene-bis-dithiocarbamate , a pesticide. [16]
Manganese superoxide dismutase (MnSOD) is the principal antioxidant in mitochondria. Several enzymes activated by manganese contribute to the metabolism of carbohydrates, amino acids, and cholesterol. [2] A deficiency of manganese causes skeletal deformation in animals and inhibits the production of collagen in wound healing. [3]
A 25-foot (7.6 m) wall of coal fly ash from the release of 5.4 million cubic yards ash slurry into the Emory River, Tennessee, in 2008. [1] The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2]
Manganese is also important in photosynthetic oxygen evolution in chloroplasts in plants. The oxygen-evolving complex (OEC) is a part of photosystem II contained in the thylakoid membranes of chloroplasts; it is responsible for the terminal photooxidation of water during the light reactions of photosynthesis , and has a metalloenzyme core ...
In 1917, three men—B.R. Jefferson, B. Edwards, and J. Marrs—discovered a manganese deposit with a high concentration of 20% to 40%. [6] Coinciding with World War I, open-pit mining operations began at the mine the same year, supplying the United States military with manganese for military equipment such as steel combat helmets.
