Web2. Phosphine Mechanisms of Action. Nath et al. [] summarized three proposed mechanisms to explain phosphine toxicity: oxidative stress, metabolic crisis and neurotoxicity.It ought to be noted that the mechanisms proposed are not mutually exclusive, a possibility that is supported by the observation that at very high concentrations, phosphine is a fast-acting …
