On an environmental spectrum of 0 - 3 Magnesium oxide fume registers 0.8. A score of 3 represents a very high hazard to the environment and 0 a negligible hazard. Factors that are taken into account to obtain this ranking include the extent of the material's toxic or poisonous nature and/or its lack of toxicity, and the measure of its ability to remain active in the environment and whether it accumulates in living organisms. It does not take into exposure to the substance.
Magnesium powder is not suspected of being highly harmful to the environment. As magnesium oxide an aquatic toxicity rating of tlm 1000 ppm has been established. "Water Quality Characteristics of Hazardous Materials", Hann & Jensen, Enviro. End. Div., Texas A&M, vol. 3 (1974).
