hows mercury contamination connected to earth?

Most mercury contamination is connected to water. The naturally occurring mercury (Cinnabar) is probably the only way to store the metal safely. Humans have been extracting large quantities of mercury from Cinnabar since the Roman Empire. The Romans extracted more than enough for all of us forever. Since it is so much easier to find more Cinnabar and extract more mercury than it is to reclaim what has been thrown out in the trash, we continue to extract more. In the not too distant future, we may find it easier to extract mercury from cremated human bodies of those who died of mercury poisoning.

Mercury is a bioaccumulative toxin that is easily absorbed through the skin, respiratory and gastrointestinal tissues.\n\nMercury attacks the central nervous system and endocrine system and adversely affects the mouth, gums, and teeth. High exposure over long periods of time will result in brain damage and ultimately death. (The term "Mad as a hatter" is thought to relate to occupational insanity caused by exposure to mercury componds in the manufacture felt hats in the 19th century) It can pose a major health risk to the unborn fetus.\n\nHumans or animals poisoned with mercury or its compounds often manifest excessive salivation, a condition called mercurial ptyalism.\n\nMinamata disease is a form of mercury poisoning.

I believe mercury has it.

mercury has a day that last 58 of our days, so the same side is away from the sun for very long periods of time.  the same way that the earth gets cold at night and warmer during the day, the same thing happens to mercury, escept that each night last for the equivalent of 29 of our days (on average).  the fact the mercury has negligible atmosphere greatly exacerbates this effect

earth to the sun is 93 million miles and the distance from mercury to the sun is about 36 million miles. so 93-36= about 57 million miles. hope this helps.

Magnesium and trace amonts of mercury.

There are a Chemical disposal company. Safe disposal so doesn't effect earth

Spin relative to what?\n\nThe spin of the Earth about its own axis causes day and night but only because the spin is not synchronised with the orbit of the axis around the sun.  Mercury spins once on its axis for every orbit and so always has the same face to the sun.  It could be said in this case that Mercury does not spin, but that is only relative to the orbit of Mercury.\n\nImagine a frame of reference that is fixed in space like the grid lines on a map.  If a planet did not spin on its axis relative to this reference, then it would have a day/night cycle that took one orbit to complete (this would be one year for the Earth).\n\nIt is also believed that the spin of the Earth contributes to the generation of the magnetic field, so if the spinning stopped or slowed (relative to any reference) we could loose the magnetic field and thus be exposed to higher radiation levels from the sun.

No, it isn't.\nhttp://www.consumerreports.org/cro/food/fish-safety-704-fish-tuna-mercury.htm

The mean surface temperature of Mercury is 452 K (178.8 °C /353.9 °F), but it ranges from 90 K (-183.15 °C /-297.7 °F) to 700 K (426.85 °C /800 °F); by comparison, the temperature on Earth varies by only about 150 K (150 °C /270 °F). The sunlight on Mercury's surface is 6.5 times as intense as it is on Earth, with the solar constant having a value of 9.13 kW/m².

Mercury is the innermost planet in our solar system, orbiting the Sun once every 88 days. It ranges in brightness from about −2.0 to 5.5 in apparent magnitude, but is not easily seen as its greatest angular separation from the Sun (greatest elongation) is only 28.3°, meaning it is only seen in twilight. The planet remains comparatively little known: the only spacecraft to approach Mercury was Mariner 10 from 1974 to 1975, which mapped only 40%–45% of the planet's surface.\n\nPhysically, Mercury is similar in appearance to the Moon as it is heavily cratered. It has no natural satellites and no atmosphere. The planet has a large iron core which generates a magnetic field about 1% as strong as that of the Earth. Surface temperatures on Mercury range from about 90 to 700 K, with the subsolar point being the hottest and the bottoms of craters near the poles being the coldest.\n\nThe Romans named the planet after the fleet-footed messenger god Mercury, probably for its fast apparent motion in the twilight sky. The astronomical symbol for Mercury (Unicode: ☿) is a stylized version of the god's head and winged hat atop his caduceus, an ancient astrological symbol. Before the 5th century BC, Greek astronomers believed the planet to be two separate objects: one visible only at sunrise, the other only at sunset.\n\nGo to:\nhttp://en.wikipedia.org/wiki/Mercury_%28planet%29

i wouldnt worry about mercury content unless she is eating a lot of albacore tuna, usually more than 3 times a week.  what you should worry about is sashimi.  there is a condition called anisakiasis which is caused by eating undercooked/raw fish and crustaceans.  she can become very ill from this infection, but humans are not the true host for these worms, so it will usually cause severe abdominal cramping and the like.  it is dangerous for a pregnant woman because the worms have to be removed by surgery.  there are other types of worms and disease that can be contracted from eating undercooked seafood, so your best bet is to stay away.  if you eat at a reputable restaurant, there shouldnt be any worry, but you never know.

Mercury actually does have an atmosphere but the planet's small size makes it hard to retain.  It is not stable.

Price: depends on where you live, since different countries have different supply chains (or delivery fees). Probably even applies to different US states. Consult online catalogues of suppliers like Sigma-Aldrich or Merck.\n\nToxicity: mercury vapours are highly toxic and cause mercury deposits in fatty tissue and jaws. Mercury poisoning causes dementia, as in "mad as a hatter" (in the 19th century, felt was made with mercury as a curing agent, and hatters working the felt usually got mercury poisoning). Mercury salts are highly toxic (blocking vital respiration enzymes).\n\nIn short: don't use mercury "at home" if you can avoid it. There are some lab uses like polarography which use the amalgating properties of the metal in order to analyze strongly electronegative elements in watery solution, but in most other applications mercury has been replaced by other materials.

You don't mention human or animal.  Salinity will effect the speciation of the mercury present and thus the toxicity.

As far as I know mercury cannot be extracted from that
