Mercury in thermometers
In modern thermometers, mercury has been replaced with a safer alloy. Mercury is only found in old thermometers.
The mercury used in old thermometers is metallic (elemental) mercury which is not readily absorbed when ingested or through the skin. Treatment is not required.
Mercury from a broken thermometer vaporises in a couple of days into the room air and is absorbed when the vapour is inhaled. However, the amounts are typically small and not likely to be toxic.
Deliver the mercury from a broken thermometer in a tightly sealed container to your pharmacy to be disposed of as hazardous waste. Collect the mercury into a dustpan with a broom, for example. Vacuuming is not recommended as it might contribute to the vaporisation of the mercury.
