Mercury vapor is odorless, colorless and very toxic. Even though liquid mercury evaporates slowly, a significant amount of mercury vapor can build up indoors after mercury is spilled, and it can be dangerous to breathe these mercury vapors.
Mercury is very toxic. It is mostly known as a neurotoxin, meaning that it harms the brain and nervous system. However, mercury is also linked to kidney and liver damage and possibly cancer. Children are especially at risk because of their brains and bodies are still developing.
