How Does Mercury Affect The Body

Mercury is a heavy metal with serious side effects like heart problems, digestive imbalance, loss of memory, breathing problems, ADD, depression, etc.

3. The EPA “safe dose” for mercury is 1,100 ppb (parts per billion) for women in their child-bearing years, as mercury levels above this value may impair neurological development in the fetus. Which

If mercury biomagnifies, in which of the organisms would you expect to find the highest mercury levels in a lake with mercury contamination?

An element on the Periodic Table called mercury was used in various ways, and this element proved to be both fatal, yet beneficial at the same time. According to an article, “The Mad Hatter Syndrome: mercury and biological toxicity”, by Leigh Erin Connealy, M.D., the author stated, “A mercury solution was commonly used during the process of turning fur into felt, which caused the hatters to breathe in the fumes of this highly toxic metal, a situation exacerbated by the poor ventilation in most of the workshops,” (Connealy). These hatters eventually developed a disease called mad hatter disease. If the people had known that mercury was a lethal element, they would have had safety regulations or substituted mercury with another safe element to make the hats. Also, according to the same article, French dentists in the late 1800s mixed mercury with silver to bond the amalgams at room temperature. These dentists had a lack of knowledge concerning the health effects of mercury inside a person. The mercury inside these patients’ mouths put them at an exceedingly high risk of mad hatter disease. This lack of knowledge caused society to be at high risk of spreading

Mercury is another toxic pollutant that may be found in the tailings and in the surface and ground water supplies of the Silver Bow Creek area. While mercury is

Wrangell-St Elias is one in four Alaskan national parks that tested positive for mercury. In some cases the levels exceeded the State of Alaska’s human consumption levels of mercury for women and children. The test was part of a multi-year U.S. geological survey and study of fish in high elevation lakes and streams. Mercury was found in all fish and can be harmful to other fish, wildlife, humans etc. The mercury was found in fish in Copper, Tanada, and Summit Lakes. Consuming high amounts of mercury can damage developing brains in babies and

While liquid gold may be a modern allegory for something desirable, there is another liquid metal that is quite the opposite of desirable. Mercury is an unusual metal in that in its standard elemental form it is a liquid. Due to the increase in industry over the last 100 years, Mercury levels have risen, which cause serious damage to humans.

Hat manufacturers once used a bright orange mercury wash to separate fur from pelts, and the common hatters who dredged around in the steamy vats, like the mad one in Alice in Wonderland, gradually lost their hair and wits. Eventually, I realized how poisonous mercury is. That explained why Dr. Rush’s Bilious Pills purged the bowels so well: the body will rid itself of any poison, mercury included. And as toxic as swallowing mercury is, its fumes are worse. They fray the “wires” in the central nervous system and burn holes in the brain, much as advanced Alzheimer’s disease does.

Once monkeys exposed to the mercury or after the injection of Hg, some of the infants was sacrificed in days 2, 4, 7, or 28 in order to exam the brain of the monkeys (Burbacher). Based on our result, the brain weights at sacrifice and brain-to-body weight showed no difference. Also, no serious medical complications were observed in any of the monkeys when they were examined. In addition the weights of infant monkeys during the study showed no significant differences in the weight gain across the three groups the average weight gain during the first 23 days of life was 13 g. In concluding, this research shows that there is no link between the mercury and autism.

Karen Nelson, Neuroepidemiology Branch, National Institute of Neurological Disorders and Stroke; and Margaret Bauman, Children’s Neurology Service, Harvard Medical School conducted a study on neuropathology of mercury toxicity. Nelson and Bauman asserted ethylmercury lacks the active transport mechanism across the blood-brain barrier that other found available to methylmercury however; they provided no evidence to support this assertion. The L system is the major transport

As already stated, many other locations around the world are affected by mercury poisoning and contamination. For example, Canada and Japan have an extensive history of mercury poisoning, including neurologic symptoms and contaminated fish. These studies have has been documented since the 1950’s in these locations. In fact, the contamination became so problematic the Ontario health department formed a task force on organic mercury in 1972. Further, recent protesting throughout Toronto has asked for Canada to address the contamination of mercury. Findings revealed levels of mercury exceeding those of international standards and included the highest recorded mercury contamination among in the western part of the world. (CITE 6)

Once released into the environment, mercury is free to be taken up by plants and animals but is not toxic unless transformed through bacterial or chemical processes into its organic form, the most famous of which is methylmercury [6], [8], [10] Methylmercury impacts several critical organ systems and particularly toxic to the development of the fetus [11]. It also bioaccumulates in living organisms, which leads to higher levels of methylmercury with each increasing trophic level [10], [12], [13]

The health hazards for humans who come in contact with contaminants from exposure to polluted water can have long term effects on the body causing possible organ failure and death. Contaminants and chemicals such lead and mercury can bring about many minor illnesses ranging from nausea, lung irritation, skin rash, vomiting, and dizziness, to the major diseases that include cancer, liver and kidney damage, disorders of the nervous system, damage to the immune system, birth defects and even death.

The article “Our Preferred Poison” in the March 2005 issue of Discover magazine brings up the issue dealing with mercury poisoning. The author, Karen Wright, writes, “Mercury is unimaginably toxic and dangerous. A single drop on a human hand can be irreversibly fatal. A single drop in a large lake can make all the fish in it unsafe to eat.” This was the opening statement in the article which first grabbed my attention, because I had not thought mercury to be such a deadly substance. After all, it is used in thermometers, so I hadn’t thought it to be as fatally toxic as Wright claims it to be.

People can come in contact with mercury in a number of ways. There is increased risk of mercury exposure in the dental, health and chemical industries. People are also at risk of consuming an unsafe amount of mercury if they eat certain things in excess amounts, such as more than 6 ounces of albacore tuna per week, or over 12 ounces of fish like shrimp, canned tuna, salmon, pollock or catfish. Exposure to mercury can cause brain damage, kidney damage, lung damage and various digestive system problems (McCoy). Perhaps the person most vulnerable to mercury poisoning is the pregnant woman and her unborn fetus. Trauma caused to infants and children as a result of
