1. Introduction. The causes of the poisonous properties of oxygen were obscure prior to the publication of Gershman’s free radical theory of oxygen toxicity in 1954, which states that the toxicity of oxygen is due to partially reduced forms of oxygen (Gerschman, Gilbert, Nye, Dwyer, & Fenn, 1954).In the same year, observations of a weak electron paramagnetic resonance (EPR) signal attributable.
