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.
The most dangerous form of mercury is monomethylmercury, which living things such as fish and humans canât easily get rid of, so it accumulates to high, toxic levels in their tissues. However, other forms of mercury also can cause problems, if exposure to it is prolonged or frequent.
