Mercury has been a well known pollutant for decades mentioned as early as the 3000 years ago by the Babylonians Mercury emissions have been seen on wild ecosystems effecting the health of many inhabitants Fish mainly from poor nutrient lakes and often in very remote areas, commonly have high levels of mercury in them, and these fish are then consumed by humans 33 states have issued fish consumption advisories because of mercury contamination
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, some electrical switches Also used in dental restoration Mercury is used in many lights sources because it can have short ultra violet wave lengths that illuminate
Mercury is very toxic Acute effects- exposure to high levels of elemental mercury in humans results in central nervous system effects such as tremors, mood changes, and slowed sensory and motor nerve function Chronic effects- exposure to elemental mercury in humans also affects the CNS, with effects such as erethism (increased excitability), irritability, excessive shyness, and tremors.
Release of naturally occurring mercury from rock and soil allows mercury to seap into our water supply Burning of coal and oil that contains small amounts of mercury Release of mercury from metal smelters Incineration of materials that contain mercury, such as batteries. Inorganic mercury compounds are the most common forms of mercury found in drinking water
U.S. EPA uses a RfD of 0.1 µg/kg body weight/day as an exposure without recognized adverse effects
Mercury is naturally occuring in rocks and soil which can leak into water supplys
Mercury is a naturally occuring element there is no way to reduce it in our water supply
