It is believed that only 55% of Mercury has been mapped, however, that 55% has yielded a number of interesting finds, there are three significant geological features on Mercury, these are: smooth plains, intercrater plains and rugged highlands. The smooth plains resemble Lunar Maria, that is, large dark basaltic plains formed by ancient volcanic eruption, found on the Earth’s moon. The Intercrater Plains are impact craters, pocked with a number of smaller craters, which cover 70% of the examined

concentration of mercury in surface water samples of Onondaga Lake in 1992 (NYSDEC/TAMS, 2002) Maximum Mean Minimum Unit Methylmercury dissolved 9.2 1.2 3.9E-02 ng/L- dis Methylmercury total 12 2 0.1 ng/L Mercury dissolved 11 3.4 0.6 ng/L- dis Mercury total 59 9.0 1.3 ng/L Different forms of mercury has been detected in Onondaga Lake including elemental mercury, monomethyl and dimethyl mercury. Mean concentration of the compounds as well as reactive mercury and total mercury has been measured

Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50 percent of the compound, is used to bind the metals together and to provide a strong, hard, durable filling. After years of research, mercury has been found to be the only element that will bind these metals together in such a way that can be easily manipulated into a tooth cavity. Is mercury in dental amalgam safe? Mercury in dental amalgam is not poisonous. When mercury is combined with other materials

acid rain and the acidification of sensitive lakes and soils in the oil sands region.Mercury is of particular concern in the northern rivers of Alberta. At the regional level mercury, is primarily emitted from coal power generation plants near Edmonton and in lesser amounts from the oil sands operations (NREI 2002). Mercury can travel long distances through the atmosphere and is eventually deposited in aquatic environments, where it can be toxic to aquatic organisms

Mercury fillings should not be used in modern day dentistry. Euan MacInnes - Inverness Royal Academy - Persuasive Everyone had an irrational fear of the dentist when they were younger. Everyone experienced that characteristic feeling of butterflies while waiting in the cream waiting room with the navy blue seats. We sat there for what felt like hours, waiting to be examined by the demon in the white coat. But what you really should have been worrying about was not the whizzing drill or the

largest source of U.S. mercury emissions to the air. Once mercury from the air reaches water, microorganisms can change it into methyl mercury, a highly toxic form that builds up in fish which is how people are primarily exposed to mercury by eating the contaminated fish. In the year 2011, the United States Environmental Protection Agency (EPA) signed a rule to reduce emissions of toxic air pollutants, specifically Mercury, from coal fired power plants. The resulting Mercury and Air Toxic Standards

1932 Minamata Sewage containing mercury was released by Chisso's chemicals works into Minimata Bay in Japan. The mercury gathered in sea creatures, causing mercury poisoning in the population. 1952 Minamata Syndrome In 1952, the first incidents of mercury poisoning occurred in the population of Minimata Bay in Japan, caused by eating fish contaminated with mercury, bringing over 500 fatalities. Since then, Japan has had the severest environmental

Mercury may have a moon appearance from the outside, but with the planet’s unique components, gravity, size, orbit, and position in the Solar System, the planet may beg to differ. This paper will demonstrate knowledge to the reader of the physical components of the planet Mercury, its position in the Solar System, and how NASA studies this distant planet. How can you explore or study a planet, so close to Earth, yet too close to the Sun? How many Mercury days are considered an Earth day? How does
