Chemical warfare first used in the 5th century BC

Chemical and biological warfare has been used long before World War One. During the Peloponnesian War in the 5th century BC, Spartans used bombs made of sulphur and pitch to overcome the enemy. During ancient and medieval times, soldiers sometimes threw bodies of plague victims over the walls of besieged cities, or into water wells. During the French and Indian wars in North America (1689-1763), blankets used by smallpox victims were given to American Indians in the hope they would carry the disease.

The first deadly gas attack came in April 1915 when the German Army dropped chlorine gas over the Allied trenches in Ypress, Belgium, Within weeks the British retaliated with a chlorine attack. The deadly rally of chemical warfare was on. In 1918 both sides used mustard gas, which seeped through masks, burning skin and searing lungs.

The first international accord on the banning of chemical warfare was agreed upon in Geneva in 1925. Despite the Geneval Protocol the Japanese used chemical warfare against China in 1930. Chemicals were also used during the Iran-Iraq conflict (1980 - 1988), a war that claimed a million victims. Iraq continued to use chemical weapons against the Kurdish minorities in the country. In 1993 another global convention banning the production and stockpiling of chemical warfare agents was signed by more than 100 countries.

The largest chemical weapons factory is in Kazakhstan, a leftover from the Soviet era. It still is ten times larger than any other chemical weapons production plant.

Botulinum toxin (BTX)

One gram of this deadly poison can kill hundreds of thousands of people. It is one of the most feared chemical weapons in excistence. Produced by the Clostridium botulinum anaerobic bacterium, it's seven different neurotoxins attach to proteins inside human nerve cells and block the chemicals used to communicate with muscles, paralyzing breathing muscles, eventually suffocating the victim.

But is also is this very property that has benefits: administered in minute quantities, it reduces painful muscle contractions... and drooling, sweating and wrinkles! It is used as cosmetic treatments under the brand names Botox, Dysport and Myobloc.

Clostridium spores are found in soil all over the world and can easily contaminate food or a wound infection. Theoretically, in the wrong hands a few grams can kill every human on earth.

Antrax

Anthrax is a disease caused by a spore-forming bacterium (Bacillus anthracis) that lives in soil, water, and vegetation. It is most commonly found in agricultural regions. Although it can be transmitted through the air deaths from anthrax is EXTREMELY RARE and it is fairly easily cured when treated early. Most countries have ample supplies of anti-microbial treatments readily available.
