HEALTH - Toxic Exposure: Mercury

Dubbed “quicksilver” by Aristotle,[1] mercury is a heavy metal with unusual physical characteristics, such as a low melting point,[2] that make it suitable for a variety of uses. It can be found in countless modern-day products, from thermometers and fluorescent light bulbs to dental fillings. Unfortunately, this unique metal is toxic to humans, and exposure can lead to neurological damage, coma, and death.[3] In fact, it is estimated that each year over 60,000 U.S. children are born at risk for learning and other disabilities as a result of prenatal methyl mercury exposure.[4] The dangers of mercury poisoning have not always been acknowledged. In fact, mercury has been used historically as a medication. The Lewis and Clark expedition used mercury products to treat syphilis, gonorrhea, and constipation.[5] Mercury is no longer used in this way, but mercury exposure is still a widespread concern, as its presence in polluted air and even seafood threaten public health.
