The first symptoms produced by a simple asphyxiant are rapid respirations and air hunger.Mental alertness is diminished and muscular coordination is impaired.However, in all cases studied, the rocks show ages considerably younger than the country rock surrounding them.Among spectral shapes identified in the study are classical plateau spectra, structured plateaus, dual plateau spectra, stepwise rising spectra, humped-shaped spectra, and saddle-shaped spectra. A major cause of the escape of gas from lunar rock is probably the impact event which ejected the rock from its place of origin to its place of discovery.Upper limits for the times at which these impact events occurred have been estimated.

Other uses incude non-reactive blanket in the manufacture of titanium and other reactive elements and as a protective atmosphere for growing silicon and germanium crystals.

Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death.

Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.

The oxygen may be diminished to 75% of it's normal percentage in air before appreciable symptoms develop.

This in turn requires the presence of a simple asphyxiant in a concentration of 33% in the mixture of air and gas.

This chemically inert element is colorless and odorless in both its liquid and gaseous forms. This gas is isolated through liquid air fractionation since the atmosphere contains only 0.94% argon.
