WebMay 11, 2015 · Know Your World War I Chemical Weapons Three substances were responsible for most chemical-weapons injuries and deaths during World War I: chlorine, phosgene, and mustard gas. Chlorine gas, used on the infamous day of April 22, 1915, produces a greenish-yellow cloud that smells of bleach and immediately irritates the eyes, … WebIn 1980, ACGIH recommended a TLV for phosgene of 0.1 ppm for an 8-h working day (ACGIH, 1980). This figure is based on data obtained by the Chemical Warfare Service before 1921 that indicated that at 1 ppm phosgene may be safe for prolonged exposure (Cucinell, 1974). It is also based on the studies of Gross et al. (1965) that showed that ...

WebThe public's health and safety are gravely jeopardised by phosgene, a highly toxic gas. In this study, phosgene was detected by excited-state intramolecular proton transfer (ESIPT) and photoelectron transfer (PET) mechanisms utilising a fluorescent probe built from a triphenylamine-anthraquinone core structure (TPAAQ) with carbonyl and imidazole … 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.
