Mercury
What exactly is Mercury? And
what does Mercury have to do with Alice in Wonderland? Mercury is a
liquid metal and the only liquid metal. For the next question youÕre going to
have to wait until I teach you more about mercury.
Although
Mercury is a very interesting element it is very toxic and only a tiny little
drip can kill you. Karen Wetterhahn, a scientist, died of Mercury poisoning. It
all happened when she was studying the affect that heavy metals have on living
things. In August 1996 Wetterhahn was putting some Mercury into a tube, She was
wearing latex gloves but that was not enough because some how just a tiny drip
went into the gloves. She did not know until 6 months later. Then she started
to lose her balance and she was having trouble hearing and seeing. Doctors said
that she had eighty times the lethal dose of Mercury. She died on June 8,1997.
There are many
symptoms of Mercury. Some are inflammation of the mouth, gum problems or
loosening of the teeth, damaged kidneys, shaking of the muscles in the arms and
legs, depression and nervousness. A large dose of mercury does even more damage
to your health. Nausea, vomiting, diarrhea, and stomach pain are common, and
even death in only a few weeks. Kids cannot play with Mercury anymore because
it is so dangerous.
Mercury was used
before Christ so nobody really knows who discovered it. The earliest
information was from the Chinese, Hindu, Egyptians, Greeks, and Romans. They
were first to mention Mercury Cinnabar was rubbed together with vinegar into a
clay dish. This released Mercury gas, which was then turned into liquid
Mercury. People who worked in mines Found Mercury and thought it was near or
close to gold, but later they realized that it was very different from gold.
Mine workers died from exposure to mercury but the trees and plants around them
were still living and unharmed.
Mercury is a silver colored metal.
This element is the only metal that is liquid at room temperature. Mercury can
be frozen (solid) at a temperature -38.85 Celsius, and it can be boiled at
365.6 Celsius. Mercury is a good conductor of electricity. It is only a little
active. It doesnÕt react with oxygen and it doesnÕt react with air very easily.
This element reacts with some hot acids but not with most cold acids.
There are several
uses of Mercury. It is used as a disinfectant, for tanning leather, insect
spray for
Potato seedlings, in
preservation of wood, embalming fluid, textile printing, and engraving. In
florescent lamps there are Mercury vapors. There are also Mercury batteries
although they arenÕt good for the environment
Because Mercury may
escape.
Long ago in the
1800s, when Mercury wasnÕt known to be dangerous, hat makers used Mercury in
their hats. They used it to treat the felt and beaver fur that lined the hats.
Later on the Mercury started to affect the hat maker. The personalities of the
hat makers became wild. When people noticed the hat makersÕ behavior they used
the expression Ò Mad as a hatterÓ. The author Lewis Carroll made a character in
AliceÕs adventure in
Wonderland. The Hat
makers have some symptoms of Mercury poisoning.
So the next time you see that book or
movie just remember that the hat maker is ÒweirdÓ for a reason.
