Phosgene is a highly toxic chemical warfare and industrial choking agent that primarily damages the respiratory system. It is a colourless or pale yellowish gas at ordinary conditions, although its characteristic odour may be noticed at sufficiently high concentrations. Chemically, phosgene is carbonyl chloride, with the formula COCl₂. It is relatively reactive and hydrolyses in the presence of water to form hydrochloric acid and carbon dioxide. Its toxicity is mainly associated with its strong reactivity with biological components of the respiratory tract. The pathological effects of a lethal exposure to phosgene are dominated by severe injury to the lungs. Unlike many rapidly acting poisons, phosgene may produce relatively few dramatic symptoms immediately after exposure. This latent period is clinically important because serious pulmonary injury can continue to develop after the person has left the contaminated environment. Following a sufficiently severe exposure, the progressive damage can result in pulmonary oedema, respiratory failure, hypoxia and death. When inhaled, phosgene reaches the moist surfaces of the respiratory tract. Because the lungs contain a very large surface area and extensive blood supply, they are particularly vulnerable. Phosgene reacts with components of cells and tissues, including proteins and ________ __________ __________ __________ _______ _____ _____ ____ ________.
