Mercury is a chemical element. Although it is a metal, it is a liquid at room temperature. Its chemical properties make it a useful substance for a variety of electronic devices and industrial applications, but Mercury is also highly toxic to humans. As a pollutant, mercury stays in the environment for a very long time.
Mercury is often used in everyday household objects so it is important to dispose of them properly:
Mercury is one of the primary pollutants of concern in Indiana because:
You should never put mercury in the trash. Items containing mercury should be taken to your local solid waste management district, or in Marion County, contact the ToxDrop (317) 327-2234 to safely collect and recycle Mercury.
Things to remember when disposing of objects containing mercury:
When liquid (elemental) mercury is spilled, it forms beads or droplets that can accumulate in the tiniest places. These droplets can emit vapors into the air that we cannot see or smell. Breathing mercury vapors can be very dangerous, depending on how much mercury is in the air and how long you are exposed the contaminated air. Small children and pregnant women are at highest risk for mercury poisoning, but mercury poisoning can impact anyone. The small amount of elemental mercury in fever thermometers and thermostats is not likely to cause serious health problems if it is immediately cleaned up.
Most small mercury spills, such as those from fever thermometers, can be cleaned up easily. Please follow the instructions for cleaning up a small household mercury spill [PDF]. If human contact with mercury occurs, call the Indiana Poison Center at (800) 222-1222.
If you spill more mercury than the amount in a fever thermometer, call the IDEM Spill Hotline at (888) 233-7745.
