Description

Phosgene: A highly toxic gas that has been used as a chemical warfare agent. It is an insidious poison as it is not irritating immediately, even when fatal concentrations are inhaled. (From The Merck Index, 11th ed, p7304) [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Overview

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.

Toxicity

The aim of the present study was to investigate toxic effects following phosgene exposure of human epithelial lung cells (A549) in vitro using a CULTEX® system. In this investigation, we have found that sensitivity to CHCl3 correlates with the capacity of the kidney to metabolize CH Cl3 to the toxic metabolite phosGene (COCl2)

Dosage Studied

The signals of the 35Cl+ and 37Cl+ ions were clearly observed with high dose-response relationships in the parts-per-billion level. The calculated alveolar molar dosage of phosgene was 9 µmol/kg. Animal studies with phosGene show a steep dose- response curve for pulmonary edema and mortality.
