Toxins There are generally four main groups of explosives: Toxins are poisons produced by living organisms. They Primary, Low, High and Blasting Agents. For purposes of are extremely poisonous and generally have a toxicity 45 this patent, the term “explosive' includes explosives, blast Several orders of magnitude greater than nerve agents. ing agents, and detonators.

Biological Warfare Organisms 55 Low Explosives Biological warfare organisms, as opposed to chemical agents or toxins, are, by definition, alive. These organisms Gunpowder-low explosive used as a propellant. include Viruses, bacteria, rickettsia, and fungi. All of them Fireworks-low explosive used as a propellant. are capable of genetic engineering, which can make them High Explosives more virulent, less treatable, and more difficult to detect. 60 RDX-high explosive made of nitric acid and Known virus warfare organisms include, but are not hexamethylene-tetramine often used in bombs as a limited to, variola virus, Venezuelan equine encephalitis primer or booster.
