The fungicide/pesticide use of mercury has declined due to environmental concerns, but mercury residues persist in the environment. Emissions from coalfired power plants and hospital/municipal incinerators are significant sources of mercury pollution.

Methylmercury, the most common, organic form of mercury, occurs by methylation of inorganic Hg in aquatic biota or sediments (both freshwater and ocean sediments).

Methylmercury accumulates in aquatic animals and fish and is concentrated up the food chain reaching highest concentrations in large fish and predatory birds.

Except for fish, the human intake of dietary mercury is negligible unless the food is contaminated with one of the previously listed forms/sources. Daily ingestion of fish can result in the assimilation of 1 to 10 micrograms of mercury/day.

Depending upon the extent of cumulative mercury exposure, elevated levels of urine mercury may occur after administration of DMPS, DMSA or D-penicillamine. Blood and especially red blood cell elemental analyses are useful for assessing recent or ongoing exposure to organic (methyl) mercury.

SOURCES:

Mercury (Hg) has three forms:

Elemental (metallic)- older glass thermometers, fluorescent light bulbs, dental amalgams, folk remedies, combustion, electrical industry (switches, batteries, thermostats), solvents, wood processing

Organic (methyl mercury)- seafood, thimerosal (preservative), fungicides

Inorganic- skin lightening compounds, industrial exposure, folk medicine, lamps, photography, disinfectants

Mercury (Hg) is a heavy metal element. It exists in three forms: elemental, inorganic, and organic. All three of these forms of mercury can be toxic, causing several health problems.

Hair mercury (Hg) is an excellent indiator of exposure to methylmercury from fish. Mercury is toxic to humans and animals. Individuals vary greatly in sensitivity and tolerance to Hg burden.

Mercury is often abbreviated Hg. It may be breathed in, ingested or absorbed through the skin and is toxic. As a vapor, mercury is odorless. 

Urinary mercury testing is considered a very accurate way to assess whether or not you have been exposed to the inorganic form of the heavy metal. There is also an organic form of mercury, which can become toxic in the body but this form of mercury is best detected in a blood test sample.

A urine mercury test measures mercury excretion from the body over 24 hours, both before and after a “provocation” or “detox” compound is ingested. A provocation compound increases the excretion of a substance such as toxic metals. EDTA, DMSA, and DMPS are examples of provocation compounds. 

Mercury is an element that is found all over the earth, in soil, rocks, and water. The issue with mercury is that if humans are exposed to it, depending on the amount, route, and duration of exposure, mercury can be toxic to humans.

Chemical Found In: Mercury (Hg) is a heavy chemical element that is emitted to the air by human activities, such as manufacturing or burning coal for fuel, and from natural sources, such as volcanoes. It is deposited, via ecosystem transport, into lakes and oceans, where it bioaccumulates in fish. According to the US EPA, "nearly all methylmercury exposures in the U.S. occur through eating fish and shellfish." In addition, mercury is used in thermometers, barometers, float valves, mercury switches, and other devices where exposure can occur with device breakage. It is also found in amalgam material for dental restorations, energyefficient light bulbs, and is used in scientific research applications.

The "Mercury, Blood" marker on LabCorp's "Heavy Metals Profile I, Blood" panel is a critical diagnostic tool for assessing exposure to mercury, a heavy metal known for its toxicity. Mercury exposure can occur through various sources, such as consumption of certain types of fish and shellfish, dental amalgam fillings, industrial emissions, and occupational hazards in industries like mining or manufacturing. The blood test for mercury is particularly effective in detecting recent exposure to organic mercury, including methylmercury, the form most commonly associated with fish consumption.

Mercury, abbreviated Hg, comes in inorganic and organic forms. Both are toxic when they accumulate in the body and are associated with serious health problems.
