Though not researched quantitatively, the Bodily Homes of liquid elemental mercury limit its absorption as a result of intact pores and skin As well as in light-weight of its really reduced absorption level from the gastrointestinal tract, pores and skin absorption would not be high.[48] Some mercury vapor is absorbed dermally, but uptake by this route is just about 1% of that by inhalation.[forty nine]

Mercury was a propellant for early ion engines in electric powered space propulsion techniques. Pros were being mercury's large molecular weight, small ionization Electrical power, low dual-ionization energy, large liquid density and liquid storability at room temperature. Down sides were concerns relating to environmental effects related to ground screening and considerations about eventual cooling and condensation of some of the propellant over the spacecraft in lengthy-period operations. The first spaceflight to employ electrical propulsion was a mercury-fueled ion thruster created at NASA Glenn Investigation Center and flown to the Room Electric Rocket Examination "SERT-1" spacecraft released by NASA at its Wallops Flight Facility in 1964.
