All blister agents currently known are denser than air, and are readily absorbed through the eyes, lungs, and skin. Effects of the two mustard agents are typically delayed: exposure to vapors becomes evident in 4 to 6 hours, and skin exposure in 2 to 48 hours. The effects of Lewisite are immediate.
Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the skin, and silver nitrate produces noticeable black stains. Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion.
Lewisite was replaced by the mustard gas variant HT (a 60:40 mixture of sulfur mustard and O-Mustard), and was declared obsolete in the 1950s. Lewisite poisoning can be treated effectively with British anti-lewisite (dimercaprol). Most stockpiles of lewisite were neutralised with bleach and dumped into the Gulf of Mexico. [25]
The US military conducted experiments with chemical weapons like lewisite and mustard gas on Japanese American, Puerto Rican and African Americans in the US military in World War II to see how non-white races would react to being mustard gassed, with Rollin Edwards describing it as "It felt like you were on fire, Guys started screaming and ...
