Phosgene is a highly toxic gas that poses a serious threat to human health and public safety. It is a gas crucial to industrial chemical processes with widespread production (∼1 million tons/year in the USA, 8.5 million tons-a-year worldwide) Phosgne is a rare exposure with strong clinical implications.
Phosgene has also proved to be a useful model for the study of those biochemical mechanisms that lead to permeability-type pulmonary edema (adult respiratory distress syndrome)
