The Dangers Of Chemical Warfare Essay, Research Paper

How many people were killed or injured in WWI due to chemical weapons? According to

the Chemical Weapons Convention web page 1,400,000 people were affected by chemical

weapons. The most serious casualties were in Russia with 475,000 injuries and 56,000 killed.

The problems of chemical warfare are upon us yet again. Saddam Hussein is currently trying to

avoid weapon inspections by the United Nations. After it has been discovered that he used

weapons during Desert Storm, can we risk confrontation with him again?

Chemical warfare can be used in many ways. The most common way is gases used in

hand-to-hand combat which are contained in grenades or canisters and thrown or fired from a

launcher. For a more widespread effect, the gas or microorganism can be sprayed from an

airplane, as in crop dusting. Often, bombs containing nuclear centers or poisonous gases are

dropped onto densely populated cities. Recently nuclear warheads and even biological toxins

have been put in missiles, such as the United States? Tomahawk missiles and Iraq?s S.C.U.D.?s.

Chemical weapons are designed to attack a person?s nervous system, eyes, nose, throat, or

skin. Chemical agents are typically airborne. Tear gas is often used by police in riot situations.

Contained in grenades, tear gas irritates the eyes and lungs, causing violent coughing, blurred

vision, and a general inability to fight.

One widely known chemical weapon is mustard gas or 1,1?-Thiobis[2-chloroethane]. It?s

molecular formula is C4H8Cl2S. The chemical structure for mustard gas is:

Cl-CH2CH2-S-CH2CH2-Cl

There is no immediate effect from this substance. In about 4 hours symptoms begin to form.

These include itching, burning, and inflammation of areas where the mustard gas comes in contact

with the skin, followed by swelling of the tissue. After 20-24 hours small blisters form around the

affected areas. Finally, fully developed blisters fill with a colorless to yellow liquid. This liquid

causes severe tissue degeneration in the blisters, which are vulnerable to infection. The wound

may take several months to heal. The estimated lethal dose is 1,500 g min m-3 (50 mg m-3 for 30

min) by inhalation and 10,000 mg min m-3 (50 mg m-3 for 200 min) by dermal exposure. The

lethal dose of liquid mustard gas for a 70 kg man is 7.0 g. Another deadly weapon is sarin. The

dose of sarin which causes death for 50 percent of animals in a test is 0.42 mg kg-1 for mice, 0.30

mg kg-1 for rabbits, and 0.0385 mg kg-1 for guinea pigs. The lethal dose for a 70 kg man is 1.7

g. Sarin?s formal name is Methylphosphonofluoridic acid, (1-methyl ethyl) ester. The molecular

formula is C4H10FO2P. The chemical structure for sarin is:

Nuclear weapons are the newest type of chemical warfare. When atoms split, a

tremendous explosion occurs, raising the temperature of the immediate area to approximately one

million degrees Fahrenheit in less than one second. Everything close by is instantly vaporized, and

a huge blast wave expands out from the epicenter of the explosion. Intense radiation from the

blast can cause damage to the DNA of an organism and improper cell mitosis. Nuclear bomb or

fallout victims can have severe radiation burns, mutations, sterility in men, and birth defects in

pregnant women.

Biological warfare is perhaps the most deadly of chemical warfare methods. Biological

warfare, or germ warfare, is the use of microorganisms, viruses, or the toxins they produce to

cause disease and death of enemy soldiers, civilians, animals, or crops. Biological warfare can be

more dangerous than other weapons because once the disease is caught by one person it may be

spread to others, thus continuing to be effective long after the original sample has been exposed.

One of the more popular biological weapons is Anthrax. There are two major types of

Anthrax. The less dangerous type lives in the soil and can be contracted by humans when

handling infected cattle or sheep. This form of Anthrax can cause nausea and illness. The more

serious form of Anthrax is airborne and can be easily dropped from airplanes. When inhaled, it

causes cardiac and respiratory arrest and immediate death.

Viruses can also be used as chemical weapons. Poxviridae, the smallpox virus, exists

today in only two places on this planet. One place is a freezer in a lab in the United States. The

other is a freezer in a lab in Russia. Each side wants to completely end the threat of smallpox.

however, each side holds the same fear: As soon as they destroy their strain of smallpox, the

other will attack with Poxviridae and defeat their country. Therefore, each side still has their own

little biological weapon. This is an example of the complicity of complete chemical weapon

banning. Everyone fears that if they give up their weapons, they will only be overtaken by
