4 Deadliest Chemical Weapons

During the World War I, a new, deadly type of weapon was used for the first time; toxic gas. Considered uncivilised prior to the war, the development and military usage of poisonous gas grenades was soon called for by the demands of both sides to find a new way to overcome the stalemate of unforeseen trench warfare. bk-ethyl First used at the Second Battle of Ypres on 22 April 1915, cylinders filled with toxic gas soon became one of the most devastating and effective weapons used in the entire Great War, killing more than 90,000 soldiers and injuring about 1.25 million. In this article, we are going to explore the 4 of most deadly chemical weapons ever conceived, their history, usage, and effects on the human beings.

  1. Mustard Gas (Yperite)

While Germans were releasing the mustard gas in year 1917 near the Belgian city of Ypres for the first time, chemist Frederic Guthrie was most likely turning in his grave. In year 1860, this British professor discovered the mustard gas, and also experienced its toxic effects first-hand for the first time. 57 years later, after its first military usage at Ypres, it got its infamous nickname, Yperite.

In the beginning, Germans planned to use the mustard gas only as a paralyzing agent. However, they soon found out, that when in sufficient concentrations, this gas could be easily lethal to the majority of the enemy soldiers.

Due to its dangerous properties, mustard gas soon became a popular chemical weapon, used in WWII, during the North Yemen Civil War, and even by Saddam Husein in year 1988. Even 150 years after its discovery, antidote is still to be discovered.

Pure mustard gas is colourless, oily liquid at room temperature. When used in its impure form, as warfare agent, it is usually green-brown in color and has an specific odor resembling mustard or garlic, hence the name. Yperite fumes are more than 6 times heavier than air, staying near the ground for several hours, effectively filling and contaminating enemy’s trenches, and killing everyone without proper protection.

Lethal dose for an adult man weighing 160 lbs is approximately 7,5 g of liquid mustard gas, when in contact with his skin for several minutes. However, when used in its gaseous form, lethality greatly depends on its concentration and on the length of exposure. Gas mask is usually not enough to be protected from this gas; it can easily penetrate the skin and kill the victim from inside. It easily passes through most of the clothes, shoes or other materials. For instance, standard rubber gloves could protect the skin for only about ten minutes.

4 or 6 hours after exposure, burning sensation appears in the affected areas, followed by reddening of the skin. After next 16 hours, large blisters appear on the affected skin, subsequently causing severe scarring and sometimes even necrosis. If the eyes were affected, temporary or permanent blindness typically occurs after few days.
