Manganese Dioxide Powder functions as an enzyme activator for steps in photosynthesis. Manganese deficiency in oat is known as gray speck. This is not a pathogenic disease but a breakdown of leaf tissue. Gray speck usually starts as a gray ovalshaped spot on the edge of a new leaf when the oat plant is in the three- to four-leaf stage. The speck appears away from the tip and may gradually spread across the entire leaf, or many such spots may appear.

Manganese Dioxide Powder is released to air mainly as particulate matter, and the fate and transport of the particles depend on their size and density and on wind speed and direction. Some manganese compounds are readily soluble in water, so significant exposures can also occur by ingestion of contaminated drinking-water. Manganese in surface water can oxidize or adsorb to sediment particles and settle to the bottom. Manganese in soil can migrate as particulate matter to air or water, or soluble manganese compounds can be leached from the soil.

Manganese Dioxide Powder is a naturally occurring element that is found in rock, soil, water, and food. Thus, all humans are exposed to manganese, and it is a normal component of the human body. Food is usually the most important route of exposure for humans. Estimated Safe and Adequate Daily Intakes of 1–5 mg manganese have been established for children 1 year of age and older through to adults; these levels generally parallel amounts of the compound delivered via the diet.

Furthermore, the most active areas of the semiconductor industry involve the use of oxides. Thus, most of the chips used in computers contain an oxide component. Till now, there are still many potential applications of materials under continuous investigation and new synthesis methods being developed.

Manganese Dioxide Powder absorption occurs primarily from the gastrointestinal tract after ingestion and from the alveolar lining after inhalation of manganese-containing dust or fumes. Several studies in animals indicate that key determinants of absorption are the absorption pathway and the specific compound in which manganese is present.
