Mercury barometers are generally used today due to their precision and dependability in measuring atmospheric force. On the other hand, digital and aneroid barometers are also well-liked for their portability and simplicity of use.
At the time while in the surroundings, elemental mercury is naturally reworked into methylmercury that bioaccumulates in fish and shellfish.
Quicksilver (liquid metallic mercury) is badly absorbed by ingestion and skin Speak to. Its vapor is the most dangerous variety. Animal info indicate a lot less than 0.01% of ingested mercury is absorbed throughout the intact gastrointestinal tract, nevertheless it may not be accurate for individuals with ileus.

Mercury is used in thermometers since it expands and contracts evenly with temperature modifications, which makes it appropriate for measuring temperature precisely.
Mercury was a propellant for early ion engines in electric space propulsion systems. Pros ended up mercury's higher molecular weight, very low ionization Electrical power, small dual-ionization energy, significant liquid density and liquid storability at room temperature. Down sides were issues relating to environmental effects affiliated with ground tests and worries about eventual cooling and condensation of a lot of the propellant about the spacecraft in lengthy-length functions. The initial spaceflight to implement electric propulsion was a mercury-fueled ion thruster formulated at NASA Glenn Investigation Middle and flown over the House Electric Rocket Examination "SERT-one" spacecraft released by NASA at its Wallops Flight Facility in 1964.
The term Hunter-Russell syndrome derives from a analyze of mercury poisoning between workers in a seed-packaging manufacturing unit in Norwich, England from the late 1930s who breathed methylmercury that was remaining used for a seed disinfectant and pesticide.[91]
