How easy would it be for terrorists to disperse a chemical agent effectively?
The options for delivering poison gas range from high to low tech. Theoretically, super toxic chemicals could be employed to foul food or water supplies, put into munitions, or distributed by an aerosol or spray method. Because of safeguards on our food and water supplies as well as the difficulty of covertly disbursing sufficient quantities of agent, this method is unlikely to be an effective means to achieving terrorist aims. Chemical agents could also be the payload of any number of specially designed or modified conventional munitions, from bombs and grenades to artillery shells and mines. However designing munitions that reliably produce vapor and liquid droplets requires a certain amount of engineering skill. Finally, commercial sprayers could be mounted on planes or other vehicles. In an outdoor attack such as this, however, 90 percent of the agent is likely to dissipate before ever reaching its target. Effective delivery, which entails getting the right concentration of agent a
