The Facts About Nerve Agents (General Information)
... What are nerve agents? Nerve agents are chemicals that affect the nervous system. The health effects are similar to those produced by some pesticides. The main nerve agents are the chemicals sarin (GB), soman (GD), tabun (GA) and VX. These agents are man-made and have been manufactured for use in ch ...
