Chemical warfare involves the use of toxic chemicals specifically designed to harm or kill humans. These chemicals can be dispersed in various ways, such as through aerial bombs or artillery shells.

The use of chemical agents like nerve agents, blister agents, and choking agents can cause immediate casualties and long-term health problems for survivors.
