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 has no value to the human body and is best thought of as poison. The effects of mercury exposure vary depending on the form and level of exposure. Acute exposure to mercury vapor can produce serious effects on the nervous system including psychotic reactions, hallucinations, suicidal tendencies and delirium.
