• Mercury is a neurotoxin that can harm the developing brains of children and infants; in adults, exposure can lead to memory loss and affect fertility and blood pressure.
• Biggest emitters- o Coal fired power plants- Coal accounts for nearly 50 percent of the electricity generated in this country—and almost 50 tons of mercury emissions annually. o Cement kilns- all the cement kilns in the U.S. combined pump out roughly 23,000 pounds of mercury every year. The group released a report last July finding that, individually, some cement kilns emit nearly one and a half times more mercury than the most polluting coal-fired power plants. o Trash incinerators. Hazardous waste, medical waste, and regular garbage incinerators release 13.1 tons (or about 26,000 pounds) of mercury every year, according to statistics from the EPA. The mercury comes from common household items, such as compact fluorescent light bulbs and thermostats, and from automobile scrap.
• Studies tend to find that environmental degradation and income have an inverted U- shaped relationship, with pollution increasing with income at low levels of income and decreasing with income at high levels of income.
• Use the GEMS- global environmental monitoring system
• Past income has been a major determinant of current pollution standards.
• The metals and toxics prove difficult to remove from drinking water by standard purification procedures and also bioaccumulate in fish that are later ingested by humans. Many of these substances accumulate into the bottom sediment that is released slowly over time.
• Health hazards- irritability, depression, kidney and liver damage and birth defects
• Pollution is best controlled by government regulation that reduce effluent discharges and that ensure proper disposal of sludge from treatment of plants and toxic wastes.
• Concentrations rise with output in the…...

...Cameron Wilbert GLG 171 4/24/13 Prof Gutierrez Mercury is a toxic element that pollutes our lakes and streams in the United States and around the world. Some might ask what mercury is. It is a silvery colored element that is naturally found in air, water, soil and even rocks. It is a dense liquid of the heavy metals category of elements. It can be commonly found in thermometers, batteries, light switches and fluorescent light bulbs. Mercury pollution comes from coal burning power plants. When it is released into the air it returns to earth via rain and snow and therefore deposited into our bodies of water. Once the mercury is in our water it is transformed by bacteria and sunlight into the most toxic form of mercury; methyl-mercury. Most mercury that is in our environment can be found as a gas; Hg. When it is high in the air it converted into Hg (ii). Methyl-mercury is so dangerous because it is highly soluble and bio accumulative in the food chain. Bio accumulation is the process where organisms take up a contaminant faster than their bodies can eliminate it. As mercury moves up the food chain it bio magnifies and the contaminants concentration becomes more and more dangerous each time it grows. It enters the food chain first by small insect and animals which are then ate by smaller fish and so on, each time the methyl is passed on to the cells of the fish until they reach the predatory biggest fish in the environment. The fish at the top of the food chain; big mouth......

...Mercury Toxicity Flamesia Starks 06/16/2013 SCI/275 Mercury Toxicity is an environmental problem that most people do not know about and sometimes it is a common household item most use every day. It affects people, animals and other wildlife. Solutions that can be easy and affective if there are used the proper way. It affects humans and wildlife and can put a permanent damage to our body and earth. Mercury Toxicity One of the issues that threaten the community that I live in is Mercury Toxicity. Mercury is a natural metal found throughout the environment. The metal is liquid at room temperature and is easily combined with other metals and it also expands and contracts evenly with temperature. Once Mercury enters and circulates in and out of our atmosphere it ends up at the bottom of our oceans and other water supply. It is persistent because it does not break down, go away or degrade. Mercury is a potent neurotoxin and if put into the body can cause decreased ability to see, hear, talk and even walk. It also causes very dramatic changes to you personality and makes you irritable and confused in most cases. There are many other things it can destroy in the body such as your brain, kidney, and lungs. It only takes a small amount of this metal as in a teaspoon to contaminate over 20 aces of water. So that is it is it is important to plan and......

... Mercury - History and Naming Mercury, the planet closest to the Sun, circles the Sun faster than all the other planets in our solar system, which is why the Romans named it after the swift-footed messenger god Mercury (Space exploration, 2013). Human observers have been looking up at Mercury since at least the time of the Sumerians – the 3rd millennium BC (The planet mercury, 2013). These Greek astronomers believed even then that Mercury (and Venus) both orbited the Sun, and not the Earth. Mercury was the god of commerce, travel, and thievery in Roman mythology, hence the naming of Mercury. Slide 2 Early beliefs of Mercury Mercury was known since at least Sumerian times roughly 5,000 years ago, where it was often associated with Nabu, the god of writing (Mercury, the sun's, 2013). Mercury was also given separate names for its appearance as both a morning star and as an evening star (Mercury, the sun's, 2013). Early beliefs thought that perhaps there were two different planets. However, Greek astronomers knew that both names referred to the same planet (Mercury). Back in the nineteenth century, astronomers made very careful observations of Mercury's orbit, but they could not explain the orbit adequately using Newtonian mechanics (The planet mercury, 2013). There were discrepancies between what they observed and what was mathematics predicted. This problem would last for decades. Einstein's General Theory of Relativity correctly predicted the motions of Mercury;......

...Jaimin Modi George Triarchou Monica Balbuena Shuyuan Qiu RE: Mercury Athletic valuation and acquisition recommendations We believe that Mercury is an appropriate target for AGI since an acquisition can be an excellent growth opportunity. First, through the acquisition AGI can take the advantages of some existing synergies. Acquiring Mercury would expand AGI’s business size and consequently produce the “one plus one is greater than two” effect. This acquisition would double AGI’s revenues, increase its leverage with contract manufacturers, and also help to expand its presence with key retailers and distributors. Moreover, if negotiated well, AGI could acquire Mercury for a lower price than the actual price of Mercury; earning more than what they’ve paid. This will be discussed further in the recommendation. Secondly, acquiring Mercury is a lower risk way for AGI to increase their growth rate. Mercury has a high growth rate of revenue, which may compensate for the low growth rate of revenue for AGI. Further, since the women’s casual line is going to be closed or consolidated, the rest of the three segments of Mercury show prosperous future prediction in margins and growth. This reflects a good acquisition opportunity. Finally, acquainting Mercury is ease of integration. This is because Mercury and AGI both are the footwear industry. And the main products of Mercury are athletic and casual footwear that are similar with AGI’s products. Both of......

...Consequences of Mercury Pollution Coming in Contact with Mercury 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 mercury exposure is exponentially worse than it would be an adult. In most cases, it causes severe nervous system problems. Exposure A EU study found that “between 1.5 and 2 million children in the EU are born each year with MeHg exposures above the safe limit of 0.58µg/g and 200,000 above the WHO recommended maximum of 2.5µg/g” (Sunderland). Exposure to MeHg in these amounts affects brain development. Stunted brain development leads to a lower IQ. A low IQ lessens one’s earning power. When just looking at the European Union, the consequences are of paramount importance. In the study, Prof Philippe Grandjean explained, "If we convert the effects of MeHg on developing brains into IQ points then the benefits of controlling MeHg......

...The World Health Organization reports that “indoor air pollution from solid fuel use is responsible for almost 2 million annual deaths and 2.7% of the global burden of disease. This makes this risk factor the second biggest environmental contributor to ill health, behind unsafe water and sanitation. Acute lower respiratory infections, in particular pneumonia, continue to be the biggest killer of young children and cause more than 2 million annual deaths. (World) In many communities like Libby, Montana, woodstove heating is a large contributor to wintertime pollution. Because wood burning typically occurs in residential areas, the intake fraction of pollutants inhaled to pollutants emitted was comparable to that of traffic pollution. To address this, Libby conducted a woodstove exchange program that encouraged residents to replace older stoves with newer, cleaner burning models. In all, 90% of woodstoves were replaced or removed. Concentrations of woodstove pollutants have been reduced by 20% - 64% during the November to February period. Additionally, preliminary analysis across the four winter seasons following the exchange shows decreased reporting of childhood wheeze. (Giles) Numerous interventions have been found that reduce indoor air pollution and the associated health effects. These interventions target the source of the pollution, the living environment and the behavior of the user. For instance, the largest reductions can be realized by transitioning from solid......

...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. The people with the most risk of damage by mercury are unborn fetuses and children. Studies seem to show that the metal has the most negative effect on the developing brain, opposed to the mature adult brain. Some scientists speculate mercury could be the cause of autism, mental retardation, cerebral palsy, and Parkinson’s disease, amongst others. I don’t know how accurate or credible these studies are though. Throughout the article Wright states that no one is sure how little mercury can be ingested before the human body shows signs of poisoning. What scientists do know is the amount of mercury the human body cannot ingest. They found this out due to accidental ingestions of various people throughout the world. The article mainly focuses on two types of mercury: methylmercury, which is found in most of the fish, and other seafood’s we eat, and alloys, call......

Mercury * Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. * Mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury. * Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays fluorescent lamps and other devices, through concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favour of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments. Mercury can be found in four different forms: * Mercury metal, which is a silver-gray liquid, is harmful to humans when it is exposed into the air and consequently breathed into the lungs. * Methylmercury "may be taken into the body by eating certain saltwater and freshwater fish, especially larger fish at the top of the food chain, such as shark, swordfish, largemouth bass, and chain pickerel." * Inorganic mercury compounds can be found in batteries, over the counter drugs, ointments,......

Pollution

...Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Today, it is becoming a serious crime to pollute the air and water. ------------------------------------------------- Forms of pollution The major forms of pollution are listed below along with the particular contaminant relevant to each of them: * Air pollution:- the release of chemicals and particulates into the atmosphere. Common gaseous pollutants include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides produced by industry and motor vehicles. Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight. Particulate matter, or fine dust is characterized by their micrometre size PM10 to PM2.5. * Light pollution:- includes light trespass, over-illumination and astronomical interference. * Littering:- the criminal throwing of inappropriate man-made objects, unremoved, onto public and private properties. * Noise pollution:- which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar. * Soil contamination occurs when chemicals are released by spill or underground......

...Activities such as bathing and washing clothes near lakes, ponds or rivers add nutrients like nitrogen into the water bodies. Land Pollution These chemicals come from industrial activities and from bad waste disposal. Soil pollution may cause health risks. They include the sound of vehicles, loud speakers, etc. Noise pollution can cause ear problems or even permanent deafness. Noise Pollution Air Pollution Water Pollution Pollution Pollution Facts & Types of Pollution by Alina Bradford, Live Science Contributor   |   March 10, 2015 10:05pm ET Pollution is the process of making land, water, air or other parts of the environment dirty and unsafe or unsuitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn't need to be tangible. Things as simple as light, sound and temperature can be considered pollutants when introduced artificially into an environment.  Toxic pollution affects more than 200 million people worldwide, according to Pure Earth, a non-profit environmental organization. In some of the world’s worst polluted places, babies are born with birth defects, children have lost 30 to 40 IQ points, and life expectancy may be as low as 45 years because of cancers and other diseases.

Mercury Toxicology

...Toxicology Report: Mercury Carmen Polat Centenary College BIO110 - Principles of Environmental Science Professor Debra DeAngelis April 7th, 2016 Every day in our lives we encounter numerous toxins. While some can be avoided, others cannot. Toxins are abundant in our environment, and there is no way to escape all of them. Some of them come from spills or accidents, some from permitted pollution, and others from everyday activities that build up toxins in the environment. This paper examines how mercury contamination, found here in New Jersey, affects the people, animals, and environment of New Jersey. Mercury is a highly toxic metal element, labeled with the atomic symbol Hg. It was known to humans thousands of years ago, and is the only metal that can be found in liquid form at room temperature (Live Science, 2016). While beautiful to look at, it is best to avoid touching it, since it is extremely toxic even in very small doses. Mercury damages the immune system, nervous system, reproductive system, and alters genetic and enzyme systems, as well as causing deformities and birth defects (USGS, 2009). It has also been found to cause autoimmune problems, and high exposures will lead to death through multi-organ failure (Azevedo, 2012). This occurs not only in humans, but also in fish and other animals that are exposed to the element. It can enter the body through wounds, inhalation, and ingestion (Live Science, 2016). One of the largest problems with mercury is that......

...4050 SEPTEMBER 18, 2009 TIMOTHY A. LUEHRMAN JOEL L. HEILPRIN Mercury Athletic Footwear: Valuing the Opportunity In March 2007, John Liedtke, the head of business development for Active Gear, Inc., a privately held footwear company, was contemplating an acquisition opportunity. West Coast Fashions, Inc. (WCF), a large designer and marketer of men’s and women’s branded apparel had recently announced plans for a strategic reorganization. The plan called for a divestiture of certain non-core assets and a renewed focus on WCF’s higher-end business, business-casual, and formal-wear apparel businesses. One of the divisions WCF intended to shed was Mercury Athletic, its footwear division. Liedtke knew that acquiring Mercury would roughly double Active Gear’s revenue, increase its leverage with contract manufacturers, and expand its presence with key retailers and distributors. He also expected that Active Gear’s bankers would quickly approach the company about a possible bid for Mercury; consequently, he wanted to complete his own rough evaluation of the opportunity before hearing the bankers’ pitch. Athletic and Casual Footwear Industry Footwear was a mature, highly competitive industry marked by low growth, but fairly stable profit margins. Despite the industry’s overall stability, the performance of individual firms could be quite volatile as they vied with one another to anticipate and exploit fashion trends. The market for athletic and casual shoes......

...Active Gear’s growth. Mercury Athletic Footwear designs and distributes athletic and casual footwear dominantly to the youth market. Mercury competes in four main product lines: men’s and women’s athletic and casual footwear. Men’s athletic footwear is the leading product for Mercury Athletic. Women’s casual footwear is Mercury’s worst performing product and post-acquisition the line may be discontinued by Active Gear. The acquisition of the Mercury Athletic division has sources of potential including an increase in Active Gear’s revenue, an increase in leverage with contract manufacturers, boosting capacity utilization and expanding its presence with retailers and distributors. Upon the review of the opportunity to acquire Mercury Athletic Footwear, the results of the financial analysis below indicate Active Gear should proceed with the acquisition. Based on the Free Cash Flow Method, considering the financial projections and assumptions for Mercury Athletic, indicate the acquisition has a positive net present value of $112,778,000 [Present Value of Future Cash Flows (59,440,000) + Terminal Value ($276,921,000) – Purchase Price ($223,583,000)]. There are also possible synergies that could make the project even more financially favorable, which are discussed below in the analysis.
