What are some common blistering agents?

Blistering agents, also known as vesicants, are chemical warfare agents that cause severe blistering and damage to the skin and mucous membranes. They can be absorbed through the skin, inhaled, or ingested, and can have both acute and long-term effects. Some common blistering agents include:

1. Mustard gas (bis(2-chloroethyl) sulfide): Mustard gas is a sulfur-based blistering agent that was first used in World War I. It is a highly toxic and persistent agent that can cause severe blistering and tissue damage.

2. Lewisite (2-chlorovinylarsine oxide): Lewisite is an arsenic-based blistering agent that is also highly toxic. It was developed during World War I but not widely used. Lewisite causes blistering and tissue damage, and can also be fatal if ingested or inhaled.

3. Phosgene oxime (diphosgene): Phosgene oxime is a rarely used blistering agent that is similar in effects to mustard gas.

4. Chloropicrin (trichloronitromethane): Chloropicrin is a lung irritant and vomiting agent that can also cause blistering of the skin and eyes. It was used in World War I and has also been used as a pesticide.

5. Nitrogen mustard (mechlorethamine): Nitrogen mustard is a cytotoxic agent that is used in chemotherapy to treat cancer. It can also be used as a blistering agent in warfare, and was developed by the United States during World War II.
