Poison
From Simple English Wikipedia, the free encyclopedia
Poisons (or toxins) are things that can make people sick or die. "Toxic" is an adjective to describe something that is poisonous.
People may die if they eat poisons or come in contact with them. They can be liquid, powder, or gas. They can be made by people and by plants or animal's bodies. Poison bottles usually have a skull and cross-bones sign on them. Sometimes poisons have an antidote that can cure people who eat or drink them.
Four types of poisons are:
- Carcinogens, or cancer-causing poisons
- Mutagens, or mutation-causing poisons such as radiation
- Teratogens, or birth defect-causing poisons
- Pollutants
In wars, some countries use poison gas against their enemies. Poison gases such as chlorine gas and mustard gas were used in World War I. Poison gases cause serious burns to the skin, eyes, and lungs.
