Carbonyl chloride inhalation exposure
WebINGESTION EXPOSURE: Phosgene (CG) is present as a gas at room temperature, so ingestion is unlikely. INHALATION EXPOSURE: Mild: No adverse health effects or only mild upper airway irritation; effects may … For higher doses of inhaled phosgene (above 150 ppm × min) a pulmonary edema often develops which can be detected by X-ray imaging and regressive blood oxygen concentration. Inhalation of such high doses can eventually result in fatality within hours up to 2–3 days of the exposure. See more Phosgene is the organic chemical compound with the formula COCl2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. It can be thought of as formaldehyde with … See more Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å, the C−Cl distance is 1.74 Å and the … See more Phosgene was synthesized by the Cornish chemist John Davy (1790–1868) in 1812 by exposing a mixture of carbon monoxide and chlorine to sunlight. He named it "phosgene" from Greek φῶς (phos, light) and γεννάω (gennaō, to give birth) in reference of the … See more • The first major phosgene-related incident happened in May 1928 when eleven tons of phosgene escaped from a war surplus store in central Hamburg.

Exposure to any chemical … WebThe largest-scale human exposures to chlorine occurred during World War I, when the gas was used as a chemical weapon. Chlorine-induced oxidative injury and normal repair of the respiratory epithelium of the airways was critical to preventing the long-term pulmonary pathology that can occur following acute injury [ 39, 40 ].
WebExposure to phosgene results in a latent (1-24 h), potentially life-threatening pulmonary edema and irreversible acute lung injury. A genomic approach was utilized to investigate the molecular mechanism of phosgene-induced lung injury. WebCalEPA (2007) derived an inhalation unit risk value of 4.9E-5 (μg/m3)-1 for benzyl chloride from the EPA oral slope factor of 1.7E-01 per mg/kg-day (U.S. EPA, 2007) by assuming …
