More than 10,000 Japanese living in the bay, who ate fish and shellfish contaminated with methylmercury, were afflicted by Minamata disease (Tsubaki & Irukayama, 1977). 5. Mercury's Effects on the Environment. Elemental mercury is volatile at room temperature and the vapors may represent a hazard to humans. from dental amalgams is inhaled as a vapor into the lungs, about 80% is absorbed (Joachim Mutter et al., 2010). It evaporates readily and travels long distances in the atmosphere, causing local, regional and global pollution. Environmental pollution is the contamination of the physical and biological components of the earth to such an extent that normal environmental processes are adversely affected. Water Pollution: Water pollution refers to the additional to the water of an excess of material that is harmful to humans, animals and fishes (Aboud, 2010). Mercury and methylmercury concentrations and loads in the Cache Creek watershed, California. Both acute and chronic Hg, exposures may result in human poisoning. In the inorganic form, mercury is absorbed from the gastrointestinal tract and acts to produce inflammatory reactions in the kidneys and gastrointestinal apparatus. 1998). Given steady environmental concentrations, mercury concentrations in individuals of a given fish species tend to increase with age as a result of the slow elimination of methylmercury and increased intake due to changes in trophic position that often occur as fish grow to larger sizes (i.e., the increased fish-eating and the consumption of larger prey items). (2011) J Occup Med Toxicol 6(1): 2. Collection and recycling of portable batteries: a worldwide overview compared to the Brazilian situation. Water pollution refers to the additional to the water of an excess of material that is harmful to humans, animals and fishes (Aboud, 2010).

As little as 1g can prove fatal to an adult human. Davis, B.J., Price, H.C., O’connor, R.W., et al. Consequences of Mercury Pollution Coming in Contact with Mercury People can come in contact with mercury in a number of ways. The release of processed mercury can lead to a progressive increase in the amount of atmospheric mercury, which enters the atmospheric-soil-water distribution cycles where it can remain in circulation for years. TACKLING MERCRY POLLTION IN THE E AND WORLDWIDE 6 can remain suspended in the atmosphere for up to 1 year, where it can be transported and deposited globally. The biogeochemical cycling of elemental mercury: anthropogenic influences. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing, and memory problems (Azimi & Moghaddam, 2013). There is need to ascertain mercury concentration in these waters to encourage actions that prevent the mercury-containing gray water from entering the sewer system. The most prominent effect of mercuric mercury is tubular necrosis in the kidney and after prolonged exposure glomerulonephritis can also be seen. Thermometers and sphygmomanometers contain mercury and so do many medical batteries, fluorescent lamps, and electrical switches. Saturday, A. Mercury and its Associated Impacts on Environment and Human Health: A Review. Elemental mercury exposure from the air is readily taken up through the lungs and about 74% is retained in the human body (Hursh et al., 1976). The second epidemic of severe methylmercury intoxication resulted in the hospitalization of about 7,000 people and the death of 460 individuals in rural Iraq in 1971 – 1972 (Bakir et al., 1973). 3.1 How does mercury accumulate in organisms? Anthropogenic release occurs from manifold industrial point sources and is estimated to constitute 2,320 tons of mercury emitted annually into the atmosphere (Nicola Pirrone et al., 2010). 6. Low exposure levels of mercury may affect the endocrine system in animals and people by disruption of the pituitary, thyroid, adrenal glands and pancreas (Rice et al., 2014). However, severe exposure may result in a lasting effect on brain function. Reduced fertility among dental assistants with occupational exposure to mercury has been noted (Nagpal et al., 2017). Such exposure may occur in laboratories, work places as well as in homes. iv. Studies in Hong Kong demonstrated that increased mercury levels were associated with infertility in both men and women (Dickman, Leung, & Leong, 1998). Among the most dangerous mercury compound is dimethylmercury (CH. Friberg, L., Skog, E., Wahlberg, J.E. Mercury is a non-transition metal and is an extremely rare element in the earth’s crust, having an average mass abundance of only 0.08 ppm (Sinicropi et al., 2010). Air Pollution: Metallic, or elemental mercury, is a liquid at room temperature and like any other liquid, it evaporates into the air, where it can be inhaled. The opinion of the scientific committee of the European Commission. Toxicity of organic and inorganic mercury species in differentiated human neurons and human astrocytes. There is good evidence linking mercury with menstrual disorders including abnormal bleeding, short, long, irregular cycles, and painful periods (Davis et al., 2001). 8. Mercury is in widespread use in healthcare facilities. Hormones that appear to be the most affected by mercury are insulin, estrogen, testosterone, and adrenaline. (2004) Sci Total Environ 327(1–3): 215–237. So the primary route of exposure to methylmercury (MeHg) for humans is consumption of fish (Habiba et al., 2017). Since mercury is so widely distributed in the Canadian environment, their risk is real and immediate, especially when effects such as impaired growth and reproduction, neurological damage, kidney damage, and weight loss, which occur at relatively low concentrations, are considered. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing, and memory problems (Azimi & Moghaddam, 2013). Iavicoli, I., Fontana, L., Bergamaschi, A.
