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.
Some elemental and chemical forms of mercury (vapor, methylmercury, inorganic mercury) are more toxic than other forms. The human fetus and medically compromised people (for example, patients with lung or kidney problems) are the most susceptible to the toxic effects of mercury.
