How You Can Keep Mercury from Rising
Avoid Buying Products with Mercury
Most products have a mercury-free alternative:
- Fluorescent bulbs — All fluorescent bulbs contain mercury. Some brands may contain less, and may be
marked with green endcaps or labeled low-mercury. Fluorescents are still a good choice for reducing mercury in the environment, because their use saves
energy. Coal-fired power plants release a lot more mercury into the environment than broken fluorescent bulbs. Recycle fluorescent bulbs by bringing them to a hazardous waste collection site.
- Thermometers — Most thermometers sold locally are mercury-free. Choices include digital, alcohol
(usually a red liquid), solar, and card thermometers. Not sure if your thermometer contains mercury? Look for the SILVER mercury inside - not red,
blue, or purple. (Digital thermometers do not contain liquid mercury.) See More Information below for results of the 2003 Thurston County Thermometer exchange.
- Thermostats — The older, round thermostats have a mercury switch inside. You can replace them with a programmable, electric thermostat, which does not contain mercury.
- Dental fillings — The amalgam used for dental fillings can contain 50% mercury, 25% silver, and 25% a mixture of copper, zinc, and tin. Ask your dentist about alternatives.
Dispose of Mercury Products Responsibly
Take unwanted household products containing mercury to
HazoHouse at the Thurston County Waste and Recovery Center. HazoHouse is open Friday, Saturday, Sunday, and Monday. This service is free to households,
but businesses must register and pay a fee (call 360-867-2491). Do not break fluorescent bulbs*; transport them in their original boxes if possible. Place
thermometers in their original containers, too, or in two zip-lock plastic bags.
*If a fluorescent bulb is broken, clean up carefully, place in double plastic bags (or equivalent), and discard in trash as solid waste.
Learn to Clean Up Mercury Spills
Avoid breathing vapors or touching broken materials.
Do not vacuum or sweep.
- Open windows to vent vapors for at least 15 minutes.
- Use stiff paper or cardboard to pick up large pieces.
- Use duct tape to pick up small pieces and powder.
- Wipe the area clean with a damp paper towel or wet wipe.
- Place all materials in a sealed container.
- Wash your hands.
- Dispose of at
HazoHouse — not in your trash. When you change a bulb, cover the flooring with a sheet of plastic.
Follow Fish consumption Advisories
People are often exposed to mercury by eating contaminated fish.
The mercury in fish has been converted to methylmercury, which is more toxic than the element found in household products. Unborn children are most at risk from methylmercury poisoning.
The Washington State Department of Health (DOH) has issued fish consumption advisories for Lake Whatcom, Eagle Harbor, Lake Roosevelt, and Sinclair Inlet
due to mercury contamination. None of these sites are in Thurston County. Budd Inlet does have a warning not to harvest seafood due to creosote and other chemicals.
When DOH issues a statewide fish advisory.
This advisory warns women of childbearing age and children under six not to eat any shark, swordfish, tilefish, king mackerel, or tuna steak due to mercury
contamination. Guidelines for the amount of canned tuna that women of childbearing age and children under six can safely eat are based on how much a
person weighs. For example, a 135 pound young woman should eat less than one 6 ounce can of tuna per week, and a five year old child who weighs about 45 pounds should eat no more than two tablespoons of canned tuna per week.
For more information on fish advisories, see the WA State Dept of Health, Fish Facts for Nutritious Health, or call 877-485-7316.
Earth Week 2007 Mercury Campaign — A campaign encouraging residents to bring in their mercury for disposal during Earth Week, brought in over 50 pounds of mercury in just 8 days!
Thermometer Exchange — Thurston County held a two-week mercury thermometer exchange in February 2003. Over 3,000 residents
brought in nearly 4,000 mercury thermometers and exchanged them for mercury-free, solar thermometers. This amounts to 4 pounds of mercury that will
be kept out of our trash and homes, where they are the most likely sources of mercury spills.
