How Does Mercury Affect The Environment

With the well-being of future generations in mind, environmental concerns have begun to establish a permanent residence atop the priority ladder for a vast array of Americans. Consequently, writers and political pundits alike are seizing this opportunity to capitalize on advocating their stance on the issue. Information, representing all positions, pours in at an unrelenting and unfathomable rate. For the average American it can be an arduous process sifting through all the rhetoric in attempt to find the real truth regarding our impact as humans on the environment; one such example is Susan Brown’s article The EPA’s Mercury Problem. In this article Brown attempts to expose hypocrisy among progressives by paralleling the Environmental Protection

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

If they flood the river to make unnatural lakes, it damage the delicate wildlife. The water contains mercury poison so it affects the aquatic animals and those consuming the aquatic animals. If anyone eats it, it can cause health issues to them.

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

For instance, certain seafoods are known to have high concentrations of mercury. The same can be found inside of certain dental fillings, such as silver fillings or mercury amalgrams.

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]

Mercury is an element that can be found in our environment through air, water and soil. Being exposed to constant levels of mercury may be detrimental to one’s overall health since it can impact the nervous, digestive and immune systems of human (WHO). In 1960, the demand of Mercury (Hg) increased significantly as it was needed in many commercial and medical practices, despite its high toxicity levels (dwivedi). Thus, the increase in mercury consumption was due to industrialization. Mercury should be gaining increased medical concerns as it can impact the lives of several classes of society. In Canada, it is found that the vast majority of marine mammals contain methylmercury (MeHg) (Laird). Methylmercury is highly more lethal than Mercury

-Mercury is a persistent substance which means a number of mercury increases in concentration as you go the in the food chain, so the higher up the chain and the higher amount of mercury. This tendency is called biomagnification. For instance, plankton contains 0.00001 ppm of mercury and if you go up 5 levels to the top of the pyramid which is a shark, it contains 1 ppm of mercury. This may pose a potential health threat to those animals and humans who consume the fishes or shark.

These toxins more often than not can have fatal consequences. Mercury is definitely one of the number one most dangerously used elements in our history. The first written record of this element is credited to Aristotle Often called the element of the ancients, mercury was dated back to as far as the 15th century BCE when it was found in ceremonial cups in Egyptian Tombs (Czaika). It is known that the Romans were the first to actually mine and use this element for everyday needs. Even at these times humans were aware of the fact that the element was poisonous. They had a mine in Spain that was worked by slaves, prisoners, and other undesirables. After the mine was dry they would use it as a prison system for the workers. Most of them would die very slow and painful deaths, bringing a long end to a short life (Sloane). In ancient China, mercury was used for a variety of medical needs. From a contraceptive, to a cough serum, to a remedy for unknown sexually transmitted diseases (Kok). People would consume mercury as if it was candy. This practice also spread to India. People did not understand the harmful toxins that they were ingesting.

Whales have a distressing increase in assimilating cancer, along with getting other illnesses like nervous and digestive system problems, liver disease, contaminant-induced immunosuppression, endocrine system damage, reproductive malformations, and growth and development issues, all because of ocean pollution (Bluevoice.org). According to “The Effects of Ocean Pollution on Marine Mammals”, by Bob Bohle, it states, “...from overfishing to greenhouse gases and global warming to the introduction of toxins into the environment – has affected every square mile of ocean on the planet and strongly impacted roughly 40 percent of marine ecosystems.” This shows far ocean pollution has come. As stated before, humans are now catching the effects of ocean pollution. Toxins from plastic and mercury that end up in fish, are entering the human food chain, which are now being linked to cancers, birth defects, immune system problems, and childhood development issues (Gianna Andrews,

The chemical poisoning in water have a great impact on humans because it can cause brain damage and physical deformities in unborn fetuses. Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels. Eventually, humans are affected by this process as well. People can get diseases such as hepatitis by eating seafood that has been poisoned. Besides,

The article describes briefly how the mercury ends up in the fish we eat, how the rain grabs the mercury from the atmosphere and deposits it into the lakes and oceans. Because of the food chain, the largest of the aquatic animals will have the highest amount of mercury, whales and sharks for example. So, communities high in whale and shark consumption will show the greatest risk of mercury poisoning.

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
