Mercury-Containing Devices

Mercury is a heavy metal that can accumulate in living tissue and cause adverse health effects. When a mercury-containing device is disposed of in a solid waste landfill or incinerator, the mercury can contaminate air, soil, surface water and groundwater. Because mercury has been detected in New Hampshire’s freshwater fish, a statewide fish consumption advisory has been issued by the Department of Health and Human Services. A number of devices contain mercury and may pose a hazard to human health or the environment when improperly managed or disposed of. Examples of mercury-containing devices include:

  • Thermostats
  • Button cell batteries
  • Quick silver maze toy
  • "Pre-1990" latex paint
  • "Light up" shoes
  • Fluorescent lamps
  • Pacemaker batteries
  • Switches
  • Hearing Aide batteries
  • Thermometers
  • Contact lens solution
  • Oven flames sensor
  • Staining solutions
  • Fixing solutions
  • Manometer
  • Nasal Spray
