Chemical warfare facts for kids
Chemical warfare has been used since the Stone Age. Since 1899, several international laws have said that using chemical weapons is illegal. But chemical weapons have still been used in wars since then.
Chemical weapons are different than regular weapons (like bombs) or nuclear weapons because they do not explode. Some chemical weapons are meant to kill people; they do this by poisoning them. Other chemical weapons are meant to "incapacitate" people (make them unable to fight back). They do this by causing pain, injuries, or sickness.
However, some living organisms make toxins (poisons). These toxins are not alive. For example, botulinum toxin is made by a bacteria, and ricin is made by the castor oil plant. Because botulinum toxin and ricin are not alive, using them to make people sick is called chemical warfare. This is explained in the Chemical Weapons Convention (CWC). The Convention also says that any toxic chemical is a chemical weapon unless it is used for legal reasons.
About 70 different chemicals have been used or stockpiled (saved up) as chemical warfare agents during the 20th century. The Chemical Weapons Convention says that all of these chemicals should be destroyed.
Although very basic chemical warfare has been used in many parts of the world for thousands of years, "modern" chemical warfare began during World War I (see the page Chemical weapons in World War I).
Since modern chemical warfare started in World War I, countries have tried to research and make chemical weapons. They have had four main goals:
- To make new, more deadly agents (types of chemical weapons)
- To create ways of delivering chemical weapons that will hurt or kill even more people
- To come up with better protections against chemical weapons
- To create better ways of detecting chemical weapons (realizing that chemical weapons are nearby)
Chemical warfare was first used during the Stone Age. Stone Age people used poisoned arrows and spear-tips. These were dipped in poisons, like venom from snakes or scorpions. Sometimes they used poisonous plants.
World War I
Main article: Chemical weapons in World War I
Poison gas was first used in World War I. France was the first country to make this type of gas. However, Germany was the first to use it in battle, on March 15th, 1915. On that day, they used tear gas against France.
The three types of gas used in World War One were:
- Chlorine gas (tear gas): Tear gas makes people cough, have trouble breathing, and go blind until the tear gas wears off
- Phosgene gas: Phosgene caused people to cough and choke much worse than tear gas. Phosgene gas is a very deadly chemical weapon. Historians think about 100,000 people died in World War I from chemical weapons. They also think that 85% of these people (85,000 people) were killed by phosgene.
- Mustard gas: Mustard gas was almost impossible to protect against. It caused very bad, painful sores on the outside and inside of the body.
At first, very basic ways of spreading these gases were used. Even so, many soldiers could be hurt or killed. This was partly because World War I was fought usingtrench warfare, so many soldiers would be in the same place at the same time, and escaping from poisonous gases would be very hard.
Germany was the first country in World War I to use chemical warfare in battle. They simply opened containers of chlorine upwind of enemy soldiers, so that the wind would carry the chlorine gas to their enemies.
Soon after this, the French started using chemical weapons too. They filled artillery projectiles with phosgene and fired them at the Germans. This was a much more effective way of using chemical weapons. It would become the most common way of delivering chemical weapons during World War I.
Chemical weapons were not used very much in World War II, except by the Japanese army during the invasion of China. This was because everybody was afraid that the other side would use weapons like theirs. Also, chemical weapons were not easy to use. They took time to use, and this made it harder for soldiers to move quickly. Also, the raw materials needed to make chemical weapons were not easy to get. This was because World War II was fought in areas which were not connected well by railroads.
It has been reported that many other countries, like the People's Republic of China, Cuba, Egypt, Iran, Israel, North Korea, Pakistan, Sudan, Syria, Taiwan, and Serbia and Montenegro, have chemical weapons.
Laws about chemical weapons
The first international law to make chemical warfare illegal was the Hague Convention in 1899.
After World War I, the Geneva Protocol of 1925 made it illegal to use chemical or biological weapons on people.
In 1997, the Chemical Weapons Convention (CWC) was created. As of the end of 2015, 192 countries had agreed to follow the CWC. According to the Organization for the Prohibition of Chemical Weapons, as of October 2015, 90% of the world's chemical weapons stockpiles had been destroyed.
The main types of agents used in chemical warfare are:
- Nerve agents, like sarin or VX
- Mustard agents
- Hydrogen cyanide-based agents
- Arsines, like lewisite
- Toxins, like Botulinum toxin
- Incapacitating agents (chemicals that make large numbers of people unable to fight back, but without permanently hurting or killing them). Examples include:
If we use chemicals (like Agent Orange or glyphosate) to destroy plants, sometimes human beings may be affected by side effects. But, we will not call it chemical warfare. Chemical warfare covers only direct attacks on human life.
