Chemical warfare agents are toxic substances designed to harm or kill people, animals, or plants during armed conflict. These agents can be gases, liquids, or solids and are often classified into categories such as nerve agents, blister agents, and choking agents. They can cause severe injuries or death, depending on the type and concentration used. The use of chemical warfare agents is prohibited under international law, specifically the Chemical Weapons Convention. This treaty aims to eliminate chemical weapons and prevent their development, production, and stockpiling. Despite these efforts, some countries and groups continue to use these agents in conflicts, raising concerns about global security and public health.
