Mercury Poisoning And Contamination 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

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

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

The Wabigoon – English River in Ontario has been contaminated with mercury for about 40 years now and the government has not approached this issue that affects most of the people of Grassy Narrows First Nation. A majority of the community has mercury poisoning, which could be fatal. Additionally, residents are forced to continue to consume contaminated food. In the 1970s, the government let the river to naturally recover itself and said that it would be better than any attempts to clean it, however, it has only gotten worse. Now, the government says that they do not want to attempt to clean the water until they are completely sure that it will not make the situation worse. Recently, scientists have suggested several solutions that have been successful in the past, but it is still unknown as to when the government will clean the water.

The gold boom of the past decade brought with it unintended consequences- severe health problems for Columbian families from mercury poisoning. Enticed by profit but unable to compete with the industrial mining operations brought in by Western entrepreneurs, some two million artisanal gold miners illegal produced two hundred thousand kilograms of gold per year using mercury to harvest the gold from alluvial deposits, as they are unable to afford industrial production methods (which use cyanide,

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

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.

Mercury is categorized as a nephrotoxin and neurotoxin. Mercury is commonly found in fluorescent light bulbs, electronics, fungicides, and medical equipment [2]. The main focus of this study in mercury is due to the large segments of the population commonly exposed to dental amalgams [3], vaccines [4], seafood [5-7], and formation of the global pollutant, such as geologic deposits of mercury released into the atmosphere.

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

To identify if MeHg has a risk to the environment, is to take the problem of high amounts of MeHg in a persons blood and asses it. MeHg is absorbed through the gastrointestinal tract, causing mercury distribution throughout the body through the blood brain. The two main analysis are blood, urine and hair. The hair samples reflect long term exposure, which helps the scientist know if the mercury was inorganic or elemental. While the blood test is to determine the elevated levels of MeHg exposure from fish consumption. Urine testing allows for both testing of inorganic and elemental exposures. low urine mercury test (5 μg/L) or hair (>1 μg/g) to accurately determine the exposure from seafood consumption. (Module 1993) These techniques provide information for the healthcare practitioner, allowing them to assess the

The article brings up many concerns dealing with mercury poisoning, a lot of things I had do idea existed. It almost scared me a little, maybe that’s what the author had intended when writing

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."
