Poison Gas

Poison gas refers to toxic chemical substances that can harm or kill living organisms when inhaled or absorbed. Historically used in warfare, such as during World War I, these gases disrupt the body's normal functions, often affecting the respiratory system. Common types include chlorine gas and mustard gas. Poison gases can cause a range of symptoms, from irritation and suffocation to severe injuries or death. Today, their use is banned in many contexts under international treaties, recognizing the devastating effects they have on human health and the environment.
