Mercury A Danger To Older Adults And Young Children

July 27, 2007

The Office of Services to the Aging (OSA) is bringing recognition to a hidden, mostly unrecognized and sometimes lethal danger to older adults and their grandchildren: mercury.

"Older adults need to be educated on the risks and dangers mercury can pose to not only themselves, but to any young children that may be visiting or residing within their home," said Sharon Gire, OSA Director. "A broken thermometer can pose enough of a risk if not handled properly."

Mercury is a powerful neurotoxin, which destroys nerves or nervous tissue, and can be found in many places in the home. A small amount of mercury, about a gram, is found in auto hood lights and street lights, as well as in fever thermometers and older devices used for measuring blood pressure in the home. Furnace thermostats can contain three or four times that amount. Some antiques, such as pendulum clocks, mirrors, and barometers can also contain large amounts of mercury. Individuals may also store bottles or jars of mercury that were saved from work or for hobbies.

Small spills, such as from a broken thermometer, can be managed but can also be dangerous if not handled quickly and appropriately. Larger spills (from two tablespoons to one pound) require professional assistance and can be costly.

Signs of mercury poisoning can include chest tightness, fever, weakness, upset stomach, swollen gums, nerve damage, personality changes, decreased vision or hearing, high blood pressure, and kidney damage. Once exposed to air, mercury vapors cannot be seen, smelled, or tasted. It is especially harmful to the brain development of children under six years of age and pregnant women.

Items suspected of containing mercury should be sealed within two plastic bags. Your local health department should be contacted for directions on safe disposal.

For more information about mercury or and the clean-up of mercury spills, please call your local county health department or call (800) MI-TOXIC.
