Phosphine toxicity

WebJan 25, 2024 · Because phosphine toxicity is based on oxidative respiration, the involvement of energy metabolism in phosphine toxicity/resistance was hypothesized [30,42,43,44]. Phosphine’s action of generating oxygen-derived free radicals, leading to cellular damage, appears to be one of the important factors associated with phosphine toxicity in insects. WebClinical signs of phosphide poisoning can include lethargy, severe GI distress that may be hemorrhagic in nature, ataxia, tremors, seizures, hyperesthesia, pulmonary edema (tachypnea or dyspnea), pallor, shock, tachycardia or bradycardia, renal and hepatic damage, disseminated intravascular coagulopathy, and methemoglobinemia.
