Mercury

Mercury Many studies have been performed to acquire specified effects of the toxic metal, Mercury, contaminating our ecosystems. Mercury is a toxic metal that can be fatal to human-beings and animals. Over the past years, many researchers have sampled water and different fishes to examine the concentrations of inorganic mercury. It has been studied that Mercury gets into the environment multiple ways. “Globally, approximately 6600 metric tons of Hg are emitted to the atmosphere annually, with 33% go to 36% attributed to direct anthropogenic emissions (3).” There are two ways that mercury can be deposited into the environment, such as wet deposition (associated with rain and snow) and dry deposition (cloud and fog deposition) (3). In this…

Mercury Claiming the life of Karen Wetterhahn, this chemical element has been proven mesmerizing but also fatally dangerous. Today I will be talking about the physical and chemical properties of Mercury, How the properties of mercury are useful in society, and the harmful effects mercury has to the human and environment. Mercury has 5 main physical properties including color, luster, conductivity, surface tension, and density. The chemical properties of Mercury include toxicity, oxidation,…

The chemical Mercury, symbolized as Hg, is an element most prominently found as a solid metal throughout Earth’s surface. It is a naturally occurring element found in Earth’s soil, water and air. To name a few examples of how Mercury is created, there are forest fires and volcanic eruptions whose combustion creates Mercury. In addition, humans also create Mercury through incinerators used in power plants. Mercury is known to be very poisonous to humans and affects many organisms ranging from…

The severity of Mercury exposure is linked to the dose that is being exposed, the age of the individual, the length and the route of the exposure (“Mercury and health” 2016). The mother who is previously exposed to a high level of Mercury can pass it on and affect the fetus during pregnancy causing impairments to the development of their brain and nervous system (“Mercury and health” 2016). It was reported that the fetus is five to ten times more sensitive to the toxicity of Mercury than the…

Mercury is the nearest planet to the sun. As such, it circles around the sun faster than all the other planets that’s why Romans named it after their swift-footed messenger god. The Sumerians also knew about Mercury since at least 5,000 years ago. It was often……………….(akin, related, connect , joint) with Nabu, the god of writing. Mercury was also given separate names for its looks as both are morning star and as an evening star. Greek astronomers knew, however, that the two names…

neurotransmitter in brain. Recent study suggests that prenatal mercury exposure is associated with increased risk for ADHD. Methylmercury has been reported in many studies that they produce mutagenic and carcinogenic effects as well. Methyl mercury produced renal carcinomas in mice, after had given 15 mg/kg in their diets for one year. Several substances have been found that has ability to modify the effect of the chronic toxicity of methyl mercury as selenium, which has antagonist effect and…

According to the World Health Organization, mercury and lead are two of the top hazardous chemicals of public health concern. Exposure to these toxicants results in serious damage in human bodies, especially young children. If human consume food or drinks that are contaminated with mercury or lead in their diet, they will cause neurological, physical, and behavioral effects, which are irreversible. The degree of severity depends on the amount of hazards in bodies (“Lead”, 2017 & “Mercury”,…

chemicals such as arsenic are toxic even in the smallest amounts. Mercury is a natural element that occurs throughout our environment and solar system. It has unique properties (i.e liquid metal at room temperature) and can be found in very small concentrations in many rocks and is the main component of the mineral cinnabar. Natural background levels can be detected in soils, living organisms, air, and water around the world. Mercury is still used today in a wide variety of products and…

Reference Ecosystem for Arimawhai Point, Great Mercury Island Introduction When a company, community, trust or private land owner plan on creating a reserve on a degraded landscape they must consider using a reference ecosystem when in the process of planning how to create the reserve. A reference ecosystem is another ecosystem that has the same features as the planned ecosystem this can include temperature, average amount of rainfall, soil type/geology, vegetation type. Reference ecosystems…

Background information on the area affected by the disaster: The diseases were first identified in the city of Minamata, Japan in 1956 which is Kumamoto Prefecture in the island of Kyushu and next it was at Niigata City, Niigata Prefecture, Japan. Minamata diseases are a neurological syndrome that results from pollution and environmental contamination. Types of ecosystems: Mercury contamination occurs through aquatic ecosystems in this case of Minamata Japan. Inorganic waste, like mercury,…
