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 a metal found in the environment, including in the water, air and soil. You can be exposed to mercury by breathing the vapors, through skin contact or by eating foods contaminated with mercury. Because the nervous system is highly sensitive to mercury, large amounts of mercury can damage the brain and kidneys. If you are pregnant, mercury can affect the developing fetus.
