Chemical weapons

Chemical weapons are substances designed to cause death or injury by releasing toxic chemicals, which can be gases, liquids, or solids that damage the human body through inhalation, skin contact, or ingestion. From a scientific perspective, these weapons exploit the principles of chemistry and toxicology, utilizing compounds like nerve agents that disrupt the nervous system or blistering agents that destroy tissue. Examples include chlorine gas used in World War I and sarin nerve agent, both of which demonstrate how chemical knowledge can be weaponized with devastating consequences.
