What was quicksilver used for in modern times

However, for safety reasons, consumer use of mercury in thermometers has become less common over the years, as digital thermometers have been introduced.

Mercury is typically found in the form of its common ore cinnabar — mercury sulfite — and can rarely be found on its own. To extract pure mercury, the ore is ground up and heated to the temperature of about 1, degrees F degrees Celsius with oxygen present in the process. Mercury vapor escapes from the ores and sulfur dioxide is removed, according to CNR. The metal is condensed and washed with nitric acid to purify it, and then distilled. Mercury can form alloys with gold, silver, zinc and cadmium, which are called amalgams.

Through those amalgams, mercury can be used to extract gold from rocks. When mercury comes into contact with gold, the gold dissolves into the mercury and then the two are separated, with the mercury being distilled off. Mercury also forms compounds with other elements. Interestingly, one of such compounds — mercury nitrate — played a role in the coining of the term "mad as a hatter.

In the 18th century people used the mercury nitrate compound to clean the pelts before they turned them into hats. Other common mercury compounds include mercuric chloride HgCl 2 — a highly poisonous salt and that was once used as a wound disinfectant. Another example is mercurous chloride Hg 2 Cl 2 , also known as calomel — an antiseptic used to kill bacteria, according to the Jefferson Lab. Both volcanoes and forest fires send mercury into the atmosphere.

Human activities, however, are responsible for much of the mercury that is released into the environment. The burning of coal, oil and wood as fuel can cause mercury to become airborne, as can burning wastes that contain mercury.

The amount of mercury deposited in a given area depends on how much mercury is released from local, regional, national, and international sources. Since mercury occurs naturally in coal and other fossil fuels, when people burn these fuels for energy, the mercury becomes airborne and goes into the atmosphere. In the United States, power plants that burn coal to create electricity are the largest source of emissions; they account for about 44 percent of all manmade mercury emissions Source: National Emissions Inventory, version 2, Technical Support Document July pp, 10 MB, About PDF ; discussion starts on page of the PDF document.

The burning of municipal and medical waste was once a major source of mercury emissions. You can view a chart showing the annual amount of emissions of mercury and mercury compounds into the air from facilities throughout the United States from to Depending on these factors, mercury in the atmosphere can be transported over a range of distances -- anywhere from a few feet from its source, to halfway around the globe -- before it is deposited in soil or water.

Mercury that remains in the air for prolonged periods of time and travels across continents is said to be in the "global cycle. One major source of mercury emissions outside of the U. The main way that people are exposed to mercury is by eating fish and shellfish that have high levels of methylmercury, a highly toxic form of mercury, in their tissues. A less common way people are exposed to mercury is breathing mercury vapor. This can happen when mercury is released from a container, or from a product or device that breaks.

If the mercury is not immediately contained or cleaned up, it can evaporate, becoming an invisible, odorless, toxic vapor. Mercury exposure at high levels can harm the brain, heart, kidneys, lungs, and immune system of people of all ages.

High levels of methylmercury in the bloodstream of babies developing in the womb and young children may harm their developing nervous systems, affecting their ability to think and learn. Learn more about health effects that can result from exposures to mercury.

Maximoff and the rest of the Avengers could only look on in shock and confusion. Quicksilver joining forces with the Avengers.
