Chemical agents such as sulfur mustard, commonly known as mustard gas, can cause severe tissue damage and lead to the formation of cavities or lesions that may persist for extended periods, ranging from 24 hours to several weeks. Other agents like phosgene gas can also cause respiratory damage and fluid accumulation in the lungs, resulting in similar prolonged effects. These agents can disrupt normal cellular processes and lead to necrosis, necessitating medical intervention for recovery.
