Mercury Roundup

Department of Natural Resources sponsoring mercury drop-off sites in Missouri

The amount of mercury found in the atmosphere, soil and water has increased during the last hundred years due to human activities. Mercury is emitted into the atmosphere by coal fired power plants, waste incineration and improper disposal of mercury products. Mercury poisoning attacks the central nervous system in all humans. Unborn children and children under the age of 12 are at the highest risk, because their nervous system is still developing.

The greatest risk of exposure from elemental mercury in products such as fever thermometers is improper handling and disposal of spilled mercury. To help reduce that exposure risk, the department is launching an effort to rid homes of mercury, with nearly 50 mercury drop-off locations throughout the state. The Mercury Roundup will end May 31, 2012.

Working with fire departments and county health offices throughout the state, the department is providing mercury drop-off locations in communities statewide. Any private citizen or nonprofit agency can leave mercury-containing instruments, such as thermometers, blood pressure cuffs, thermostats or switches, at any of these sites.

This program does not include compact fluorescent bulbs, or CFLs. For more information on the proper disposal of CFLs, see Household Compact Fluorescent Lamp Use and Disposal, Fact Sheet--PUB2273.

Citizens seeking to dispose of items at these sites should first secure the item in two zip top plastic bags and then place it in a crush-proof sealed container, such as a coffee can,  plastic margarine tub, or plastic beverage bottle.

Department staff will collect the dropped off items at the end of May for consolidation and transport them to Jefferson City to recycle what can be recycled and properly dispose of the rest.

A person who is uncomfortable with transporting mercury instruments, or who has large quantities of mercury, can contact the department's spill line at 573-634-2436 to arrange to have items picked up.
