A very qualitative term which includes any and all trace gases which have a greater @O04362@ potential than oxygen (for example, ozone, peroxyacetyl nitrate, hydrogen peroxide, organic @P04510@, NO3, etc.). It is recommended that alternative, more definitive terms be used which define the specific oxidant of interest whenever possible.
