Mercury Thermometers

Mercury has been used in glass thermometers since the 1700s.   A typical home “fever thermometer” contains between 0.5 and 3 grams of elemental mercury.  When a thermometer breaks, the mercury inside enters the environment.  Depending on the ambient temperature, some of the mercury will volatilize.  In it’s vapor form, mercury easily enters the body where it accumulates.

Digital thermometers are accurate and safer alternatives to mercury thermometers.  In 2000, San Francisco banned the sale of mercury thermometers at retail stores within City limits.  Use RecycleWhere to find a safe disposal option for old mercury thermometers.
