Chemical and Biological Weapons

Period 9/10

Kristen Sposetta, Aaron Mohr, DestaneeGoosby, Taylor Host


Chemical Weapons (also called “the poor man’s atomic bomb”) - chemical substances that can be delivered using munitions and dispersal devices to cause death or severe harm to people, animals, and plants

Biological Weapons (also called “germ weapon”) - a weapon of mass destruction that uses a biological agent or pathogen such as bacteria or a virus that is harmful to people and plants

The use of biological weapons against an enemy for hostile purposes or during armed conflict is called biological warfare

pros advantages

Easy to produce and quantify

Cheaper than nuclear weapons and overall cheapest weapon

Easy to conceal

Conventional weapons (bombs, grenades, etc.) explode once, kill a few hundred people, mutilate thousands of others. Biological agents, on the other hand, can spread from person to person, killing more of the enemy

Chemical weapons can give an army a tactical, battlefield advantage

cons disadvantages

Backfire, since containment is difficult once a contagious disease has begun spreading

Difficult to deliver to the enemy

Does not immediately incapacitate an enemy, other weaponry is more effective

Unpredictable, you may infect your own troops

Lasts for a long time, for example, anthrax can live in soil for up to 50 years

examples of biological weapons

Bacteria- such as anthrax, brucellosis, tularemia, and plague

Viruses- intracellular parasites, smallpox, and yellow fever

Fungi- pathogens that can be weaponized for use against crops to cause disease

Toxins- poisons that are weaponized after extraction from snakes, insects, spiders, marine organisms and other animals

Examples of biological weapons
examples of chemical weapons

Mustard gas, Sarin, Chlorine, hydrogen cyanide, tear gas, poisoned arrows, boiling tar, and arsenic smoke

Substances such as inflammatory or combustible mixtures, smokes, or gases that can irritate, burn, incapacitate, and poison

The first chemical weapon used effectively in battle was chlorine gas, which burns and destroys lung tissue

Examples of chemical weapons

Chemical Weapon Examples

Mustard gas

Tear gas
