Mercury Spills

Mercury is a toxin that can affect the human nervous system and damage the liver and kidneys. Even small amounts of spilled mercury are a health hazard, because mercury volatilizes at room temperature and people may be exposed to toxic levels through inhalation.

Spilled mercury is also a concern because it contributes to mercury pollution of the atmosphere. Mercury in rain contaminates lakes, causing significant fish contamination. Even a small amount of mercury is a concern — the atmosphere brings about one gram of mercury each year (an amount equal to the mercury contained in one fever thermometer) to a 20-acre lake.

Information on the health effects of mercury exposure is available from the National Library of Medicine.
