The First Step in Dealing with Mercury Poisoning

Mercury is uniquely both a heavy metal and a liquid at room temperature. Only three other elements are liquids at room temperature. Its atomic number is 80. Other metals near it on the Periodic Chart include silver, gold, cadmium, and lead. Gold is the only one of these that is more dense. Being both a metal and liquid had made it both useful and harmful. The usefulness has been known for centuries. The harm we are only beginning to learn.

Mercury was known in ancient China and India and was found in Egyptian tombs placed there 3500 years ago. Mercury metal comes from cinnabar, or mercury sulfide. Most of the world’s supply comes from California, Texas, Spain, and Italy. It has been used for years in sphygmomanometers, thermometers, and barometers because the column of liquid can be 13 times shorter than if it were water. The problem is that mercury, mercury vapor, and all soluble salts of mercury are extremely poisonous.

This fact has not kept mercury from being used in a wide variety of ways. Street lights that give off a blue light are generally mercury vapor lights. Mercury sulfide, in the form of vermillion, is used as a paint to slow the growth of barnacles on ships. Mercury has also been used in fluorescent lights, and when they are broken indoors, they give off enough poisonous mercury vapor to be a health risk. Mercury is still used in dental amalgams and some cosmetics. When the author was a child, it was common to paint mercurochrome on a wound to keep it from being infected. All this has changed today.

Today we are much more aware of the far reaching negative effects of heavy metals on health. In fact, these metals have no known need in the body. Their presence is nearly always negative. They get into our bodies in a variety of ways. More specific for this article, the abundant use of mercury in the past has now poisoned water, land, and seas. Mercury poisoning in fish, especially tuna and swordfish, is a problem and fish must be monitored continually.

A few products that use mercury are listed here, each one posing a threat to cause mercury poisoning: air conditioner filters, battery manufacturing, burning newspapers and building materials, cosmetics, fabric softeners, fungicides, industrial waste, lumber, paints, photoengraving, psoriasis ointment, sewage disposal, suppositories, and wood preservatives.

The list of the negative effects of mercury poisoning is frightening. Here are a few: adrenal dysfunction, anorexia, brain damage, deafness, discouragement, eczema, joint pain, nerve fiber degeneration, speech disorders, etc. Metals can directly or indirectly damage DNA bringing an increase in cancer.

Symptoms like those above often include sensory impairment such as vision, hearing, or speech problems, lack of coordination, and disturbed sensation. The type of symptom and the degree of the problem will depend on the individual, the metal causing the poisoning, and the duration of the exposure.

The multitude of products that once used or presently use a form of mercury is staggering. How many of these are in landfills today leaching their poisons into the ground water? Yes, city water systems are monitored for mercury poisoning. But what are wells and springs?

This article is not designed to frighten you but to alert you to possible danger of mercury poisoning. We can’t do anything about landfill leaching into our present water sources. Neither can we do anything about decreasing the number of products using mercury in some form. But we can do whatever possible to make our drinking water safe.  If you have any doubts about your water, it is best to filter it before drinking or cooking with it. An activated charcoal filter for example promises to remove up to 95% of any mercury or other heavy metals in the water. It does this through its ability to adsorb the toxins. The investment in a good water filter will not only be worth the money, but will give the added benefit of bringing you peace of mind.
