Mercury manometer to evaluate strain Numerous historic programs built use of your peculiar Actual physical Homes of mercury, especially to be a dense liquid along with a liquid metal:
The main system of mercury toxicity involves its irreversible inhibition of selenoenzymes, such as thioredoxin reductase (IC50 = 9 nM).[53] Although it has many capabilities, thioredoxin reductase restores natural vitamins C and E, as well as a range of other significant antioxidant molecules, again into their minimized sorts, enabling them to counteract oxidative injury.[54] Considering that the price of oxygen consumption is particularly substantial in Mind tissues, manufacture of reactive oxygen species (ROS) is accentuated in these vital cells, earning them especially liable to oxidative hurt and especially dependent on the antioxidant defense supplied by selenoenzymes.
EPA workers cleanse up residential mercury spill in 2004 Mercury thermometers and mercury gentle bulbs are usually not as frequent since they used to generally be, and the amount of mercury they comprise is unlikely to be a overall health concern if dealt with thoroughly.
Though not examined quantitatively, the Actual physical Houses of liquid elemental mercury limit its absorption through intact pores and skin and in light of its pretty reduced absorption fee from the gastrointestinal tract, skin absorption would not be superior.[forty eight] Some mercury vapor is absorbed dermally, but uptake by this route is just about one% of that by inhalation.[49]
The mercury battery is actually a non-rechargeable electrochemical battery, a Most important mobile, that was typical in the midst of the twentieth century. It had been used in a wide variety of apps and was accessible in different measurements, specially button measurements.

Mercury was a propellant for early ion engines in electric powered House propulsion programs. Pros were mercury's superior molecular fat, minimal ionization Strength, reduced twin-ionization Power, superior liquid density and liquid storability at room temperature. Drawbacks were concerns pertaining to environmental effect linked to ground tests and issues about eventual cooling and condensation of a lot of the propellant within the spacecraft in very long-duration functions. The initial spaceflight to make use of electric powered propulsion was a mercury-fueled ion thruster created at NASA Glenn Research Middle and flown about the House Electrical Rocket Exam "SERT-1" spacecraft introduced by NASA at its Wallops Flight Facility in 1964.
Exposure to mercury – even compact quantities – may well result in severe medical problems, and is a threat to the event of the kid in utero and early in life.
Slovenia: The Idrija mine, A different historically important web-site, has yielded significant quantities of mercury from cinnabar deposits.
