Mercury was found in Egyptian tombs that date from 1500 BC; [31] cinnabar, the most common natural source of mercury, has been in use since the Neolithic Age. [ 32 ] In China and Tibet , mercury use was thought to prolong life, heal fractures, and maintain generally good health, although it is now known that exposure to mercury vapor leads to ...
Idrija is one of the few places in the world where mercury occurs in both its elemental liquid state and as cinnabar (mercury sulfide) ore. The subterranean shaft mine entrance known as Anthony's Shaft ( Antonijev rov ) is used today for tours of the upper levels, complete with life-sized depictions of workers over the ages.
Mercury most commonly refers to: Mercury (planet), the closest planet to the Sun; Mercury (element), a chemical element; Mercury (mythology), a Roman deity;
Heritage of Mercury. Almadén and Idrija is a joint UNESCO World Heritage Site in Almadén, Castile-La Mancha, Spain, and Idrija, Slovenia. The property encompasses two mercury mining sites. In Almadén mercury has been extracted since Antiquity, while in Idrija it was first found in 1490. [1]
There are seven stable isotopes of mercury (80 Hg) with 202 Hg being the most abundant (29.86%). The longest-lived radioisotopes are 194 Hg with a half-life of 444 years, and 203 Hg with a half-life of 46.612 days. Most of the remaining 40 radioisotopes have half-lives that are less than a day.
A spacecraft has beamed back some of the best close-up photos ever of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above ...
The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). It is found either as a native metal (rare) or in cinnabar (HgS), corderoite, livingstonite and other minerals, with cinnabar being the most common ore. [69]
mercury is the third most frequently found toxic substance in waste facilities in the United States (ATSDR, 2001). Mercury is now widespread in the environment (EPA, 1997; ATSDR, 2001). The long-range atmospheric trans-port of mercury (Ebinghaus et al., 2001), and its conversion to organic forms through bio-accumulation in the aquatic
