Mercury Poisoning
Mercury Poisoning
In December 2011, EPA issued the first national standards for mercury pollution from power plants. MATS are the first national standards to protect American families from power plant emissions of mercury and toxic air pollution like arsenic, acid gas, nickel, selenium, and cyanide. The standards will slash emissions of these dangerous pollutants by relying on widely available, proven pollution controls that are already in use at more than half of the nation's coal-fired power plants. Read the press release | Learn more about these actions | Read the final rule (PDF).
Mercury poisoning (also known as hydrargyria or mercurialism) is a disease caused by exposure to mercury or its compounds. Mercury (chemical symbol Hg) is a heavy metal occurring in several forms, all of which can produce toxic effects in high enough doses. Its zero oxidation state Hg0 exists as vapor or as liquid metal, its mercurous state Hg+ exists as inorganic salts, and its mercuric state Hg2+ may form either inorganic salts or organ mercury compounds; the three groups vary in effects. Toxic effects include damage to the brain, kidney, and lungs. Mercury poisoning can result in several diseases, including acrodynia (pink disease), Hunter-Russell syndrome, and Minamata disease.

Symptoms of mercury poisoning typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure.

What is Gold Film Technology?
The heart of Jerome is the well-proven gold film technology. A thin gold film, in the presence of mercury vapor or hydrogen sulfide gas, undergoes an increase in electrical resistance proportional to the mass of mercury vapor or hydrogen sulfide in the sample.
When the sample button is pushed, an internal pump pulls ambient air through a scrubber filter and into the flow system. The sample air is drawn over the gold film sensor.
The instrument determines the amount of the toxic gas adsorbed and displays the measurement in micrograms per cubic meter (µg/m3) or milligrams per cubic meter (mg/m3) for mercury, and parts per million (ppm) or parts per billion (ppm) for hydrogen sulfide.
Check out our newest additions to the Home of Jerome below.
