空气中的锰：锰元素和锰化合物几乎没有蒸气压力，但锰向周围空气的转运是由于工业来源的悬浮含锰微粒的散发，以及含锰土壤的侵蚀。大气中这些锰微粒的半衰期取决于微粒的大小，并且通常以天为单位计量。在日光下ＭＭＴ经迅速光化学降解为四氧化锰（Ｍｎ３Ｏ４）和半衰期约为?
Manganese in the air: Manganese and manganese compounds have almost no vapor pressure, but the transport of manganese to the surrounding air is due to the emission of industrial-origin suspended manganese-containing particles and the erosion of manganese-bearing soils. The half-life of these manganese particles in the atmosphere depends on the size of the particles and is usually measured in days. In daylight, the photodegradation of MMT to MnO 4 (Mn 3 O 4) and the half-life of ~
