| - Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, and other scientific apparatus, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alcohol-filled, digital, or thermistor-based instruments.
- Mercury (symbol Hg) is a chemical element, a transition metal with atomic number 80 on the periodic table.
- Mercury is used to make light-bulbs, which is why they need to be recycled properly and not simply thrown in the bin, especially in areas where domestic waste is incinerated. The best incinerators can remove 50% of heavy metals from their smoke plume so light-bulbs that are thrown out are a major source of mercury pollution.
- Exposure to mercury had a negative effect on many species, as well as robots. A canister of mercury was used to corrode and disable a Gold Assassin who was on board a Roman sailing vessel. (COMIC: Golden Slumbers) Mercury poisoning was a common complaint among sailors. Amy Ivans, a passenger of the Lankester, was being poisoned with small doses of mercury, administered by De Requin.

- Mercury is a chemical element with the symbol Hg and atomic number 80 on the periodic table. It is a heavy metal that is liquid under standard temperature and pressure. The remaining debris of the Caretaker's array contained mercury, hydrogen, helium, and argon.

- Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is mostly obtained by reduction from cinnabar. Cinnabar is highly toxic by ingestion or inhalation of the dust. Mercury poisoning can also result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury.

| - Exposure to mercury had a negative effect on many species, as well as robots. A canister of mercury was used to corrode and disable a Gold Assassin who was on board a Roman sailing vessel. (COMIC: Golden Slumbers) Mercury poisoning was a common complaint among sailors. Amy Ivans, a passenger of the Lankester, was being poisoned with small doses of mercury, administered by De Requin. (AUDIO: Cryptobiosis) Many devices required mercury to function. For example, on Go-Ray, the First Doctor, John and Gillian acquired mercury to repair a cardium reactor. (COMIC: Enter: The Go-Ray) The First Doctor falsely claimed that his TARDIS' fluid link had run out of mercury as a ruse to explore the Dalek City. (TV: The Daleks) The Second Doctor visited the Panjistri homeworld to stock up on mercury. (PROSE: Timewyrm: Apocalypse) Later, the mercury in the fluid links evaporated, forcing the Doctor and Jamie McCrimmon to evacuate the TARDIS. The Doctor acquired more mercury on Space Station W3. (TV: The Wheel in Space) The Fourth Doctor acquired some needed mercury in 1931 Chicago, unknowingly defeating 's plans by doing so. (PROSE: The Duke of Dominoes) The Eighth Doctor visited a podule orbiting Jupiter in search of mercury for his TARDIS' fluid links. (PROSE: To the Slaughter) The planet Vulcan had mercury swamps on its surface. (TV: The Power of the Daleks) Skaro had geysers of mercury. The Dalek Emperor attempted to kill Zeg near one of them. (COMIC: Duel of the Daleks) The Acteon Galaxy had asteroids made of mercury. (AUDIO: Neverland) The Eighth Doctor visited Rontan 9 during the Last Great Time War in search of mercury to repair his TARDIS' fluid links. (PROSE: Natural Regression)

Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, and other devices though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alcohol-filled, galinstan-filled, digital, or thermistor-based instruments. It remains in use in scientific research applications and in amalgam material for dental restoration. It is used in lighting: electricity passed through mercury vapor in a phosphor tube produces short-wave ultraviolet light which then causes the phosphor to fluoresce, making visible light.
