Annyira baromi bonyolult elõállítani hogy az elsõt totál véletlenül fedezték fel, rovarirtó szer után kutatva.

"One author estimates the start-up costs to produce a biological weapon at less than $1 million. Another points out that "a sophisticated program designed to produce a fissionable device would probably cost hundreds of millions of dollars, whereas type A botulinal toxin, which is more deadly than nerve gas, could be produced for about $400 per kilogram. A group of C/B experts, appearing before a UN panel in 1969, estimated that 'for a large-scale operation against a civilian population, casualties might cost about $2000 per square kilometre with conventional weapons, $800 with nuclear weapons, $600 with nerve-gas weapons, and just $1 with biological weapons'" (Douglass, Joseph D., Jr., and Neil C. Livingstone. America the Vulnerable: The Threat of Chemical and Biological Warfare. Lexington, MA: Lexington Books, 1987.) Another source estimates that the production of 1,000 kilograms of sarin (GB) nerve agent in a small laboratory would cost about $200,000. However, it is unclear if such estimates take into account the added costs that might have to be paid to procure equipment and/or materials on the black, as opposed to the open, market."
