An early scientific analyze of mercury poisoning was in 1923–1926 because of the German inorganic chemist, Alfred Inventory, who himself turned poisoned, together with his colleagues, by breathing mercury vapor which was becoming produced by his laboratory products—diffusion pumps, float valves, and manometers—all of which contained mercury, as well as from mercury that were accidentally spilt and remained in cracks during the linoleum ground covering.

The SERT-1 flight was followed up from the SERT-two flight in 1970. Mercury and caesium had been favored propellants for ion engines right until Hughes Exploration Laboratory carried out experiments finding xenon fuel to be an appropriate substitution. Xenon is currently the popular propellant for ion engines, as it has a superior molecular weight, little if any reactivity as a consequence of its noble fuel mother nature, and substantial liquid density below delicate cryogenic storage.[117][118]
Mercury is usually a pure element from the earth, with a median abundance of somewhere around 0.05 mg/kg from the earth’s crust, with sizeable area versions. Mercury ores which have been mined typically consist of about a single p.c mercury, Even though the strata mined in Spain normally contain as much as twelve-fourteen % mercury. While about twenty five principal mercury minerals are identified, just about the only real deposits which were harvested for the extraction of mercury are cinnabar.
