Mercury has great cocktails and probably one of my favorite old fashioned's in town but what I think sets mercury apart from other cocktail bars is the service. The bartenders/waitresses are attentive but not overbearing...
Small-scale gold refining is a major cause of air pollution from mercury. EPA helped design a low-cost mercury capture system that is simple to build and install, uses locally available materials, and reduces mercury emissions by at least 80%.
Note on Mercury and Cancer: No human data currently ties mercury exposure to cancer, but the data available are limited. In very high doses, some forms of mercury have caused increases in several types of tumors in rats and mice. When EPA published its Cancer Guidelines in 2005, the Agency concluded that environmental exposures to inorganic mercury and methylmercury are not likely to cause cancer in humans. Technical information about mercury and cancer is available in:
Exposure to methylmercury most commonly occurs when people eat kinds of fish and shellfish that have high levels of methylmercury in their tissues. Almost all people have at least small amounts of methylmercury in their bodies, reflecting the widespread presence of methylmercury in the environment. U.S. Centers for Disease Control and Prevention (CDC) data show that most people have blood mercury levels below levels associated with possible health effects. Methylmercury, however, is a powerful neurotoxin, and people exposed to high levels may experience adverse health effects. If you are concerned about your exposure to methylmercury, you should consult your physician.
Exposures to metallic mercury most often occur when metallic mercury is spilled, or when products that contain metallic mercury break, so that mercury is exposed to the air. If you are concerned about your exposure to metallic mercury, you should consult your physician.
Some people who drink water containing inorganic mercury substantially in excess of the maximum contaminant level (MCL)maximum contaminant level (MCL)The highest level of a contaminant that EPA allows in drinking water. MCLs ensure that drinking water does not pose either a short-term or long-term health risk. EPA sets MCLs at levels that are economically and technologically feasible. Some states set MCLs which are more strict than EPA's. for many years could experience kidney damage. If you are concerned about an exposure to inorganic mercury, you should consult your physician.
Eating contaminated fish is the number one cause of mercury exposure in America. Mercury is spewed into the air from coal-burning power plants and factories. That pollution can travel halfway around the world and then settle into lakes, rivers, and oceans, where it is absorbed or ingested by small organisms and then starts working its way up the food chain, its concentration rising with each step. Big predatory fish, like sharks or tuna, can have especially high concentrations in their bodies.
If you have concerns about your mercury consumption, ask your physician for a blood mercury test. Women with a high blood mercury level who are planning to start a family may decide to postpone pregnancy for a few months until that level drops.
Although the liquid mercury in fever thermometers is less toxic than the form of mercury found in fish, inhaling it can still cause damage to the lungs, kidneys, and brain. In some cities, you may be able to exchange your old mercury thermometer for a free digital replacement. Household hazardous waste collection facilities and many pharmacies also collect and safely dispose of mercury thermometers.
If a mercury thermometer breaks, make sure that children do not touch the liquid mercury or inhale its vapors. Carefully sweep the little silver balls of mercury into a disposable plastic container and seal the container shut. Then take the container to your local household hazardous waste collection facility. Do not flush the mercury down the toilet, vacuum it, or throw it in the garbage can.
The most popular alternative to mercury fillings is composite, or porcelain, fillings. However, these fillings contain the hormone-disrupting chemical bisphenol A, or BPA. Gold fillings appear to be the safest alternative but are considerably more expensive. Discuss the benefits and drawbacks of each option with your dentist.
In late 1990s, NRDC and others successfully pressed for the removal of thimerosal, a preservative that contains ethyl mercury, from childhood vaccines to limit mercury exposure. The flu vaccine is the only routine childhood vaccine that still sometimes includes thimerosal, but parents can request a mercury-free version. Some of the combined diphtheria and tetanus vaccines may contain trace residues of thimerosal, but the amounts are extremely small.
Summary: Mercury combines with other elements, such as chlorine, sulfur, or oxygen, to form inorganic mercury compounds or "salts", which are usually white powders or crystals. Mercury also combines with carbon to make organic mercury compounds. The most common one, methylmercury, is produced mainly by microscopic organisms in the water and soil. More mercury in the environment can increase the amounts of methylmercury that these small organisms make.
Metallic Mercury is a dense liquid that vaporizes easily at room temperature. Metallic mercury is not easily absorbed into unbroken skin. However, it vaporizes, even at room temperature. The higher the temperature, the more vapors are released. Mercury vapors are colorless and odorless, though they can be seen with the aid of an ultraviolet light. Metallic mercury is used to produce chlorine gas and caustic soda, and is also used in thermometers, dental fillings, and batteries. Mercury salts are sometimes used in skin lightening creams and as antiseptic creams and ointments.
Action Levelspdf icon[579 KB] - Guidance for action levels in the instance of elemental or metallic mercury releases or spills. The action level guidelines are based on the ATSDR Chronic Minimal Risk Level and the EPA Reference Concentration.
Mercury is a naturally-occurring chemical that exists in several forms, metallic (elemental), organic and inorganic. Most health concerns focus on methylmercury in fish, and on metallic mercury, which has been used in many products in the past. Elemental mercury is a shiny, silver-gray liquid metal that scatters into droplets when spilled. At room temperature, liquid mercury will vaporize (evaporate) into air. Mercury vapor cannot be seen or smelled. Common items containing elemental mercury include: thermometers, thermostats, blood pressure units, barometers, gas pressure regulators, florescent light bulbs, and antiques.
Metallic mercury is also called elemental mercury, quicksilver, or simply mercury. It is a shiny, silver-colored metal that is liquid at room temperature. Because mercury has unique properties, it has been widely used in industrial processes, scientific instruments, consumer products, medicine, dentistry, and certain ethnic practices.
Exposure to mercury is a health concern. Exposure to mercury can occur by breathing in mercury vapors, eating or swallowing foods or water contaminated with mercury, or having skin contact with mercury droplets or beads. The route of exposure that poses the greatest risk of health effects is inhalation of mercury vapor. Exposure to mercury can be measured in biological samples.
Mercury is also a concern for the environment. It does not degrade and is not destroyed by burning. In its various forms, mercury cycles through the environment, and some forms accumulate in the food chain (for example, as methylmercury in fish). Mercury's toxicity, persistence and widespread use make proper disposal and recycling essential.
When mercury spills, it must be cleaned up quickly and completely to minimize exposure to toxic mercury vapors. Mercury can be measured in environmental samples. Wastes that contain mercury, or are contaminated by mercury, are regulated and must be disposed of as hazardous waste. Some mercury spills must be reported.
The Department works to prevent mercury pollution. The Partnership to Reduce Mercury in Schools targeted mercury removal in schools. A packet of nine brochures was developed to help school personnel identify mercury sources and reduce or remove the risk of a mercury spill.
Mercury exposure is an environmental reportable condition in Colorado under Regulation 6 CCR 1009-7. All laboratories must report all blood and urine test results where mercury levels exceed 0.5 μg/dL (or 5 μg/L) for blood and 20 μg/L for urine, within 30 days of the test.
Mercury can harm the central nervous system and kidneys.
Mercury builds up in the tissue of fish, which people and animals then eat. There is no way to remove or reduce mercury once it's in fish, even through cooking. Fetuses and young children are at highest risk of health effects from eating mercury in fish, so they, pregnant people, and breastfeeding women have to be especially careful.
Although human exposure to mercury occurs most frequently through eating contaminated fish, there are other ways to be exposed to mercury. People have been exposed by inhaling mercury vapors from broken fluorescent lamps, gas regulators, and home fever thermometers. Rarely, people are exposed by swallowing mercury.
Recent studies suggest that human activity contributes 50 to 70% of the mercury in the environment globally (Office of Air Quality and Standards Report to Congress, 1997). Once it enters the environment, it circulates in and out of the atmosphere until it ends up in the bottoms of lakes and oceans where it is transformed by bacteria into a form that can accumulate in fish tissue.
