Mercury is a metal. Research related physicians and medical specialists: While this is still part of the teratological evaluation procedures today, the field of Teratology is moving to a more About 3% of newborns have a "major physical anomaly", meaning a physical anomaly that has cosmetic or functional significance.Causes of teratogenesis can broadly be classified as: Approximately 4 to 5 percent of birth defects are caused by exposure to a teratogen. Drugs known to be capable of acting as teratogens include, but are by no means limited to, ACE inhibitors like benazepril (brand name: … Liquid metallic mercury is hardly absorbed from the gastrointestinal tract. Mercury vapor (inorganic) is produced by the burning of fossil fuel, or by volcanic eruption, and is dispersed widely in the atmosphere. ): Molnar, R. E., 2001, Theropod paleopathology: a literature survey: In: Mesozoic Vertebrate Life, edited by Tanke, D. H., and Carpenter, K., Indiana University Press, p. 337-363. It is often thought of as the study of human congenital abnormalities, but it is broader than that, taking into account other non-birth developmental stages, including puberty; and other organisms, including plants. Klaassen (ed. It also can cause hearing and vision problems. Teratogens may cause a birth defect in the child. Elemental (inorganic) mercury is found in thermometers and dental amalgams. Home medical testing related to Mercury -- Teratogenic Agent: Teratology is the study of abnormalities of physiological development. Fossils bearing evidence of congenital deformity are scientifically significant because they can help scientists infer the evolutionary history of life's developmental processes. Or a teratogen may halt the pregnancy outright. "Teratogenesis" redirects here. Inorganic mercury is also poorly absorbed, i.e., around 2% of ingested mercuric bryotoxicity in experimental animals, but only a few elements (e.g., mercury, lead, etc.) Natural emissions of mercury into the air and water occur from volcanic eruptions, through weathering of rocks, degassing of the earth’s crust and evaporation of water. The likelihood and severity of defects may be affected by the stage of pregnancy that the exposure occurred at. For the Revocation extended play, see Rogers, J.M., Kavlock, R.J. (1996). These effects can result in a baby being born with a birth defect. Read about other experiences, ask a question about Mercury -- Teratogenic Agent, or answer someone else's question, on our message boards: Studies designed to test the teratogenic potential of environmental agents use animal model systems (e.g., rat, mouse, rabbit, dog, and monkey). Women who consume methylmercury during pregnancy can bear children who have neurological issues because methylmercury has toxic effects on the nervous system during embryonic development. Methylmercury (MeHg) is an organic form of mercury that can damage the developing brains of human fetuses. Copyright © 2014 Health Grades Inc. All rights reserved. The classes of teratogens include radiation, maternal infections, chemicals, and drugs.. Mercury -- Teratogenic Agent: There is strong evidence to indicate that exposure to Mercury during pregnancy may have a teratogenic effect on the fetus.

Last Update: 13 August, 2015 (5:07) These may include growth retardation, delayed mental development or other cong… Teratogen: Any agent that can disturb the development of an embryo or fetus. Rare types of diseases and disorders in related medical categories: Early teratologists exposed pregnant animals to environmental agents and observed the fetuses for gross visceral and skeletal abnormalities. If you come in contact with high levels of mercury during pregnancy, it can cause real problems for you and your baby. for medical facilities in specialties related to Mercury -- Teratogenic Agent: A teratogen is a substance that can cause birth defects. Mercury is toxic to human health, posing a particular threat to the development of the child in utero and early in life. Other doctor, physician and specialist research services: Mercury (Hg) is a major teratogen, considered one of the most toxic substances on earth and a serious global pollutant. Research quality ratings and patient safety measures Commonly undiagnosed diseases in related medical categories: Mercury is a naturally occurring substance that exists in a variety of chemical forms. There are billions of potential teratogens, but only a few agents are proven to have teratogenic effects. Evidence for congenital deformities found in the fossil record is studied by paleopathologists, specialists in ancient disease and injury. are known to be human teratogens. "Developmental toxicology". The related term developmental toxicity includes all manifestations of abnormal development that are caused by environmental insult.

In C.D. Mercury can damage many parts of your body, including your lungs, kidneys and nervous system (that includes the brain, spinal cord and nerves).
