Chemical and biological warfare (CBW) refers to the use of toxic chemicals or biological agents with the intent to cause death, injury, or other harmful effects on humans, animals, or the environment. This chapter provides an introduction to the world of chemical and biological warfare, exploring its definition, historical context, and the importance of understanding these threats.
Chemical warfare agents (CWAs) are toxic chemicals that can cause harm to humans, animals, and the environment. These agents can be gases, liquids, solids, or aerosols. Biological warfare agents (BWAs) are living organisms or toxins produced by living organisms that can cause disease or death in humans, animals, or plants. The scope of CBW includes the development, production, stockpiling, and use of these agents, as well as the means to deliver them.
The use of chemical and biological agents in warfare has a long and tragic history. The first known use of a chemical weapon was by the Assyrians in the 7th century BC, who catapulted a mixture of bitumen and sulfur against their enemies. However, the modern era of chemical and biological warfare began in the 19th century with the development of mustard gas by the German chemist Friedrich Wöhler.
During World War I, chemical weapons were used extensively on the battlefields of Europe. The most infamous incident was the release of chlorine gas by the German army at Ypres in 1915, which resulted in the deaths of thousands of soldiers. The use of mustard gas and other agents continued throughout the war, leaving a lasting legacy of suffering and loss of life.
After World War I, the use of chemical weapons was outlawed by the Geneva Protocol of 1925. However, the threat of chemical and biological warfare persisted, and the development of new agents continued throughout the 20th century. The most notorious use of biological weapons occurred during World War II, when Japan attempted to use plague-infected fleas to infect Chinese soldiers.
