The Increase In Mercury Consumption In Canada

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?

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

Additionally, the effect of mining rocks is clear all over the world. For instance, according to the book, ‘The Amazon Gold Rush and Environmental Mercury Contamination,” the author mentions mercury contamination of waterways in the Amazon around gold mines. The problem is the extensive effluent that is discharged into the rivers and streams. The effect on marine life can be deleterious. The importance of the Amazon area to sustain the global equilibrium in the environment has been recognized worldwide. This has been much more accentuated in the present days due to the intense debate related to global warming. Consequently, all initiatives or studies directed to a better knowledge and management of that huge environment are welcome and needed.

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.

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)

Another claim anti-vaxxers make is that vaccines contain mercury which is toxic to humans (Ross, np). Thimerosal, which was in multi-dose vaccines to prevent bacteria growth, did in fact contain traces of mercury (Ross, np) (CDC, np). However, there are two types of mercury: methylmercury and ethylmercury (CDC, np). Methylmercury, which is found in some kinds of fish, is toxic to humans in high doses, while ethylmercury is cleaned out of the body rapidly and is less likely to cause any harm, especially at low doses (CDC, np). Thimerosal contained a very low dose of ethylmercury, and studies showed it would not be toxic to humans, aside from some minor side effects such as redness or swelling after injection (CDC, np). Even so, the FDA decided to remove thimerosal from vaccines back in 2001 (Ross, np).

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]

My ocean issue is Mercury pollution in fish. Mercury pollution in fish is an issue because it causes defects in human and wildlife development and function. If mercury polluted fish is consumed by a pregnant woman or one that is breastfeeding it causes many problems for the unborn baby. According to nrdc.org “more than 75,000 babies are born each year with a greater risk of learning disabilities because of their mothers’ mercury exposure” those disibililaties include learning and Intellectual dissorders. Wildlife is affected by this as well. If birds consume the fish it become very hard for them to either care for their eggs or rarely lay eggs at

n addition to mercury becoming a natural occurrence and cannot be helped when it affected the environment, many animals, especially the fish were dying from the mercury poisoning in their habitats. “Fish at the top of the food chain and at lower depths exhibit higher levels of contamination as there is more methylmercury at those depths, and they also ingest fish that are tainted with the toxic chemical” (Ruiz, 2013).

Mercury pollution occurs from industrial sources such as mining, power plants and coal combustion centers. When mercury is released from the sources, it can travel halfway around the world before it ever enters into the waterways and contaminates the fish that we then eat. Through the trade of those fish, people in every continent are at risk for mercury pollution. Newborns are also at risk of mercury pollution due to the consummation of fish by their mothers, thousands of babies are at risk every year of impaired motor skills (“Reduce Mercury Pollution”). In order to reduce the pollutants of mercury we need to implement a policy to clean up sites already contaminated, limit the amounts discharged into the water and provide consumers on tips to reduce their exposure to it.

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.

The CTBC claims that e-waste accounts for approximately 40 percent of these three toxins that end up landfills, noting that "just 1/70th of a teaspoon of mercury can contaminate 20 acres of a lake, making the fish unfit to eat."
