Q. The other day I had a fever and was taking my temperature. When I was shaking my thermometer, the bottom broke off and it spilled down the sink drain. I was too sick to do anything about it that day.
Today, I am feeling better and when I searched the Web for ideas about disposal I got freaked out. What should I do about the mercury that went down the drain?
A. This is a serious situation because liquid mercury from a thermometer can release mercury vapors that are toxic. They can also get into wastewater and cause dangerous pollution.
The mercury is probably caught in the U-shaped trap under the sink. A plumber could help you clean out the trap into a bucket. If you opt to do this yourself, though, be sure to wear disposable latex gloves. After removing the trap, empty the contents into a bucket. Carefully pour off as much water as you can and then use an eyedropper to pick up the mercury. Put it into a zip-top sealable plastic bag. Seal the eyedropper in a separate bag and take both to a hazardous waste collection site.
Your experience underscores the importance of eliminating all mercury-containing thermometers. Instead, consider a digital thermometer. One new device is the Temple Touch Thermometer. It provides a digital readout in 6 seconds. This is especially convenient for parents with young children since it does not require rectal or oral placement.
