Description Dr Wilford Lee Lewis first synthesized lewisite in 1918 for use as a vesicant chemical warfare agent. This synthesis was based on the thesis work of Julius Arthur Nieuwland at the Catholic University of America. Its discovery was made too late for use during World War I, but was later weaponized and garnered the nickname ‘Dew of Death.’ Several countries have manufactured and stockpiled lewisite; however, none have officially reported its battlefield use.
Physical properties Lewisite is also a systemic poison, which can result in pulmonary edema, diarrhea, restlessness, weakness, subnormal temperature, and low blood pressure. Severity of symptoms, in order of appearance, are blister agent, toxic lung irritant, tissue absorption, and systemic poison. If inhaled in high enough concentrations, lewisite can cause death in as little as 10 min. Common routes of exposure into the body are through the eyes, skin, and inhalation. Lewisite is an oily colorless liquid when pure. “War gas” is amber to dark brown in color with a geranium-like odor; pure lewisite has little, if any, odor. Lewisite is much more volatile than mustard agents. Often, lewisite is mixed with mustard to lower the boiling point of the mixture. The military designation for the mustard/lewisite mixture is (HL). Lewisite is insoluble in water and has a specific gravity, which makes it heavier than water. It has a vapor density more than seven times heavier than air. Lewisite has a low level of flammability, with no flash point or flammable range identified.
Uses Chemical warfare agent. Lewisite is an arsenical vesicant/blister agent used in chemical warfare.
