Toxic Mercury

  • Naturally occurring element, present as a contaminant in fossil fuels. 

  • Used by people for centuries.  Mercury is liquid at room temperature, dense, electrically conductive, and toxic.

  • Uses take advantage of many forms of mercury: liquid metal, salts, gas, and amalgams which are chemical combinations with other metals.

  • Mercury as a pollutant travels far and wide on wind and water currents. 

  • Accumulates in the environment in fish, wildlife, and humans.

  • Causes nerve damage, respiratory problems and birth defects.

  • Resulted in fish consumption advisories for all inland Wisconsin lakes and streams.

Thermometer Programs

Disposal of fever thermometers by the public is VOLUNTARY.  There is no requirement that people must remove them from their homes.  This is a good idea, but it is not required.  Bring your old mercury thermometers, and other mercury devices, into Clean Sweep for disposal.

Dane County Partners

Mercury is a very mobile pollutant that is present in many different waste streams.  Therefore, several cooperative efforts have been undertaken in Madison and Dane County to promote the use of alternative mercury-free products and the proper handling and disposal of mercury-containing devices.  The local mercury partners include: Madison Metropolitan Sewerage District, Dane County Public Works and Health Departments, City of Madison Public Works and Health Departments, DNR, Wisconsin Dental Association, medical facilities, universities, and secondary schools.
