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 ...
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.
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]
Additionally, chemical burns can be caused by biological toxins (such as anthrax toxin) and by some types of cytotoxic chemical weapons, e.g., vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime. Chemical burns may: need no source of heat; occur immediately on contact; not be immediately evident or noticeable; be ...
Sulfur mustard, commonly known as mustard gas, was used as a chemical weapon in World War I and more recently in the Iran–Iraq War. Sulfur mustard is a vesicant alkylating agent with strong cytotoxic, mutagenic, and carcinogenic properties. After exposure, victims show skin irritations and blisters.
Delivered in artillery shells, mustard gas was heavier than air, and it settled to the ground as an oily liquid. Once in the soil, mustard gas remained active for several days, weeks, or even months, depending on the weather conditions. [44] The skin of victims of mustard gas blistered, their eyes became very sore and they began to vomit.
“The existing evidence suggests that this compound can cause liver, developmental, blood and endocrine effects in the human body,” Jamie Alan, an associate professor of pharmacology and ...
A chemical weapon agent (CWA), or chemical warfare agent, is a chemical substance whose toxic properties are meant to kill, injure or incapacitate human beings.About 70 different chemicals have been used or stockpiled as chemical weapon agents during the 20th century, although the Organisation for the Prohibition of Chemical Weapons (OPCW) has an online database listing 35,942 chemicals which ...
