Sulfur Mustard

Sulfur mustard, commonly known as mustard gas, is a chemical warfare agent first used during World War I. Despite its name, it is not a gas but a liquid that can evaporate into a vapor. It causes severe blistering and damage to the skin, eyes, and lungs upon exposure. The compound is odorless or has a somewhat sickly sweet smell, making it difficult to detect. Although primarily associated with military use, it has also been studied for its effects on health, and exposure can lead to long-term health problems. It's classified as a weapon of mass destruction.
