Inorganic mercury compounds are formed when mercury combines with other elements, such as sulfur or oxygen, to form compounds or salts. However, some people are exposed to high levels of mercury, including acute exposure (exposure occurring over a short period of time, often less than a day). Health effects of methyl mercury poisoning have been observed and documented from studies performed on the people affected by the Japan and Iraq incidents. The lower 95% confidence limit of this estimate was 58 µg/L. Health & Safety in the Home, Workplace & Outdoors, Clinical Guidelines, Standards & Quality of Care, All Health Care Professionals & Patient Safety, Addressing the Opioid Epidemic in New York State, Learn About the Dangers of "Synthetic Marijuana", Help Increasing the Text Size in Your Web Browser. All humans are exposed to some level of mercury. Infants born to women who were poisoned with methylmercury had developmental abnormalities and cerebral palsy. But these limits are set for methyl mercury primarily from fish, not for ethyl mercury from vaccines. Inorganic mercury compounds are used in some industrial processes and in the making of other chemicals. If you are concerned for your health or your family's as a result of a potential exposure to mercury, get in touch with your health care provider. Most had blood mercury levels … Share this article via email. Saving Lives, Protecting People, What You Need to Know About Mercury in Fish and Shellfish, Centers for Disease Control and Prevention, Section 2: Biomonitoring helps to shape policies that affect our health, Section 3: Biomonitoring teaches us about nutrition, Section 4: Biomonitoring helps us respond to health emergencies, Section 5: Learn more about biomonitoring, Dioxins, Furans and Dioxin-Like Polychlorinated Biphenyls, NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol), Organophosphorus Insecticides: Dialkyl Phosphate Metabolites, Per- and Polyfluorinated Substances (PFAS), Polybrominated Diphenyl Ethers (PBDEs) and Polybrominated Biphenyls (PBBs), U.S. Department of Health & Human Services. Inorganic mercury is mercury combined with other chemical elements such as chlorine, sulfur or oxygen. Exposure to methylmercury is of particular concern for children and unborn babies because their nervous systems are still developing and may be more vulnerable. Very high mercury vapor concentrations can quickly cause severe lung damage. However, studies have shown that amounts of mercury greater than 85 micrograms per liter (µg/L) pose harm. When it comes to mercury levels in our bodies, a normal whole blood mercury level is considered to be between zero and nine nanograms per milliliter (ng/mL). Centers for Disease Control and Prevention. Ethylmercury (etHg) is derived from the metabolism of thimerosal (o-carboxyphenyl-thio-ethyl-sodium salt), which is the most widely used form of organic mercury. blood - 5 ng/mL (nanograms per milliliter). Mercury serves no role in the human body, so technically there shouldn't be any mercury in your bloodstream. Vapors may be present in such workplaces as dental offices, smelting operations, and locations where mercury has been spilled or released. EPA has found mercury in water to potentially cause kidney damage from … Symptoms of long-term high level methylmercury exposure include disturbances in vision, hearing and speech, as well as tingling and numbness in fingers and toes, lack of coordination and muscle weakness. Maximum levels must be set for certain contaminants in order to protect public health. CDC scientists found measureable mercury in most of the participants. For most people, an elevated blood mercury level is associated with eating fish and other seafood containing organic mercury. Methylmercury consumed by the mother can enter her fetus and can also be passed on in breast milk to nursing infants. Contaminant levels must be kept as low as can reasonably be achieved following recommended good working practices. Organic Mercury: People may be exposed when they eat fish or shellfish contaminated with methylmercury. Methyl mercury is absorbed through the digestive tract and distributed throughout the body. Biomonitoring data can also help scientists plan and conduct research about exposure and health effects. Many of these advisories are for fish with elevated mercury levels. A common form of organic mercury is methylmercury which is produced by microorganisms in water and soil, and which accumulates in fish. However blood and urine mercury levels don't necessarily relate to the mercury load in your body tissues or severity of clinical symptoms. Thimerosal and phenylmercuric acetate are other types of organic mercury compounds made in small amounts for use as preservatives. This information is available by calling 518-402-7800 or by visiting the NYSDOH website. Its lipid-soluble property allows for easy passage through the alveoli into the bloodstream and red blood cells (RBCs). Mercury is a naturally occurring metal that combines with other elements to form inorganic mercury compounds. This methylmercury production has been primarily attributed to anaerobic bacteria in the sediment. All blood mercury levels for persons in the. In the same 2003–2004 NHANES, CDC scientists measured mercury in the urine of 2,538 participants aged six years and older. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Most people are exposed to low levels of mercury, often through chronic exposure (continuous or intermittent long term contact). Biomonitoring studies on levels of mercury provide physicians and public health officials with reference values so that they can determine whether people have been exposed to higher levels of mercury than are found in the general population. Inorganic Mercury: People may be exposed if they work where inorganic mercury compounds are used. Mercury levels at or above these values do not mean that you will develop adverse health effects. Information and advice, particularly for marketplace fish such as tuna, swordfish, and shark is available by calling the federal Food and Drug Administration consumer food safety hotline (1-800-FDA-4010) or by visiting their website. Rome, 27 June 2003 - Experts convened by the UN Food and Agriculture Organization (FAO) and the World Health Organization (WHO) recently announced agreement on recommendations regarding safe intake levels for a variety of different chemicals occurring in food, including cadmium and methylmercury, the most toxic form of mercury. In the body, elemental mercury can be converted to inorganic mercury. Elemental mercury is a silvery, odorless liquid that evaporates slowly at room temperature, becoming a vapor.
