Mercury Poisoning

Mercury is one of the most poisonous, naturally occurring substances on earth. It is so harmful that even a single atom of mercury in the body can do loads of harm. The World Health Organization claims that there is no safe level of mercury in the body. Mercury poisoning directly or indirectly can cause a number of chronic health problems. In this article, we shall see the ill effects of mercury poisoning, by covering most of the mercury poisoning symptoms.

Causes of Mercury Poisoning
Mercury poisoning from fish is one of the most common causes of mercury poisoning in humans as well as animals. Mercury poisoning from tuna, swordfish, etc. pose a greater risk as compared to smaller fish species. Studies have shown risk of mercury poisoning from sushi made from fishes like shark, swordfish, blue fin tuna is very high. Therefore, one should avoid these high-end fishes and stick to two helpings of fish or shellfish per week. Exposure to mercury can also occur through breathing air contaminated with mercury vapors, eating foods that contain mercury residues, mercury amalgam dental restorations, bio-accumulation of mercury in soil, water and air. Stationary combustion of coal also leads to mercury saturation in atmosphere. Gold production, non ferrous metal production, waster disposal, cement production, caustic soda, pig iron, steel, mercury production, etc. all add to mercury concentration in water, soil and air. Even hair bleaching products are known to cause classic signs and symptoms of mercury poisoning.

Mercury Poisoning Symptoms
There are a number of mercury poisoning symptoms that affects many organs and systems in the body. The following table will cover a list of chronic mercury poisoning symptoms affecting various organs and systems of the body.

Mercury Poisoning Treatment
Mercury poisoning treatment includes identification of the source of poisoning. After identification of the source, one needs to begin decontamination of the clothes, skin and eyes as needed. In case of medical therapy, the patient is put on immediate chelation therapy. The chelation therapy is used in case of acute inorganic mercury poisoning. The FDA approved chelating agent that can even be used in children is Dimercaptosuccinic acid (DMSA). Other chelation agents include 2,3-dimercapto-1-propanesulfonic acid (DMPS), D-penicillamine (DPCN), or dimercaprol (BAL). One should keep in mind chelation therapy can prove to be fatal, like EDTA used for treatment of mercury poising lead to death of a 5 year old autistic boy in August 2005.

This was some information on causes and effects of mercury poisoning. The prognosis of mercury poisoning shows this condition is partially or fully reversible. This can only be achieved if the source of poisoning is totally removed. However, an extensive mercury exposure can lead to irreversible damage especially in fetus, infants, children and pregnant women. Hope this article has helped cover some useful information related to mercury poisoning and helped you know more about its health consequences.
