Diagnosis of elemental or inorganic mercury poisoning entails figuring out the heritage of exposure, Bodily conclusions, and an elevated physique burden of mercury. Although whole-blood mercury concentrations are typically below 6 μg/L, eating plans full of fish can lead to blood mercury concentrations increased than two hundred μg/L; It's not that practical to measure these degrees for suspected situations of elemental or inorganic poisoning because of mercury's small 50 percent-daily life while in the blood.
By far the most critical situations of mercury poisoning influence youngsters and fetuses of pregnant people today and other people who breastfeed (chestfeed) and consume massive amounts of fish with superior mercury material.
Thermometers containing mercury have been invented while in the early 18th century by Daniel Gabriel Fahrenheit, although earlier attempts at creating temperature-measuring devices filled with quicksilver had been described during the 1650s.[eighty three]: 23 Fahrenheit's mercury thermometer was determined by an earlier design and style that used Liquor rather then mercury; the mercury thermometer was significantly a lot more accurate than Those people making use of Liquor.
Resulting from its Actual physical properties and relative chemical inertness, liquid mercury is absorbed extremely poorly by intact skin along with the gastrointestinal tract.[132] Mercury vapor is the first hazard of elemental mercury. Because of this, containers of mercury are securely sealed to stop spills and evaporation.
