Mark I, Nerve Agent

Nerve agents are the most toxic of the known chemical warfare agents. They are chemically similar to organophosphate pesticides and exert their biological effects by inhibiting acetylcholinesterase enzymes.

  • G-type agents are clear, colorless, and tasteless liquids that are miscible in water and most organic solvents.
    • GB (Sarin) is odorless and is the most volatile nerve agent; however, it evaporates at about the same rate as water.
    • GA (Tabun) has a slightly fruity odor, and
    • GD (Soman) has a slight camphor-like odor.
  • VX is a clear, amber-colored, odorless, oily liquid. It is miscible with water and soluble in all solvents. It isthe least volatile nerve agent.
