Based on a study of the literature and our own experience treating fisherman poisoned fry mustard gas, this article outlines the clinical effects, and toxicological and mutagenic properties of the agent. Mustards are very persistent chemical agents that easily penetrate clothing. Mustard gas usually causes clinical symptoms after the liquid penetrates the skin or the vapor is inhaled. Skin lesions are similar to first- or second-degree burns and usually heal spontaneously in 4 to 6 weeks. Eye symptoms are photophobia and reduced vision. Following inhalation of the agent, pulmonary edema and long-term dyspnea may be seen. As mustard gas is an alkyldting substance, it is conceivable that the risk of developing cancer may be increased, as observed in people who were involved with the production of mustard gas and in animals exposed to the gas. Also, transient significantly increased sister chromatid exchange rates have been found in fishermen exposed to mustard gas.Patients exposed to mustard gas must be treated immediately after exposure. Treatment should consist of cleaning of the exposed skin and clothes with an antigas powder and water and soap. The skin lesions should be treated as bums. Eye lesions and respiratory problems should be treated symptomatically.
