What are the types of mercury?

Mercury is an element and a metal that is found in air, water, and soil. It exists in three forms that have different properties, usage, and toxicity. The three forms are called elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. Elemental mercury is liquid at room temperature.

Which form of mercury is the most toxic?

The toxic effects of mercury depend on its chemical form and the route of exposure. Methylmercury [CH3Hg] is the most toxic form. It affects the immune system, alters genetic and enzyme systems, and damages the nervous system, including coordination and the senses of touch, taste, and sight.

Which mercury is harmful to humans?

Elemental (Metallic) Mercury Metallic mercury mainly causes health effects when inhaled as a vapor where it can be absorbed through the lungs. Symptoms of prolonged and/or acute exposures include: Tremors; Emotional changes (such as mood swings, irritability, nervousness, excessive shyness);

What is dimethyl mercury used for?

For example, a major use of dimethylmercury is to calibrate certain research equipment such as Nuclear Magnetic Resonance (NMR). Inorganic mercury salts reportedly can be substituted for most of these operations.

Is it OK to touch mercury?

If you touch it, a small amount may pass through your skin, but not usually enough to harm you. Mercury is most harmful when you breathe in the vapors that are released when a container is open or a spill occurs. Pregnant women, infants and young children are particularly sensitive to the harmful effects of mercury.

Can you touch liquid mercury?

If you touch it, a small amount may pass through your skin, but not usually enough to harm you. Mercury is most harmful when you breathe in the vapors that are released when a container is open or a spill occurs.

How much dimethyl mercury is toxic?

Absorption of doses as low as 0.1 mL can result in severe mercury poisoning. The risks are enhanced because of the high vapor pressure of the liquid.

What do you do if you accidentally touch mercury?

Initial treatment following exposure to spilled mercury includes washing with soap and water if mercury came into contact with the skin and getting fresh air if the vapors are inhaled.

What are the three types of mercury?

Mercury exists in three forms: elemental mercury, inorganic mercury compounds (primarily mercuric chloride), and organic mercury compounds (primarily methyl mercury).

What are some examples of mercury?

batteries

  • such as thermometers and barometers
  • electric switches and relays in equipment
  • lamps (including some types of light bulbs)
  • dental amalgam (for dental fillings)
  • skin-lightening products and other cosmetics
  • pharmaceuticals.
  • What is the most toxic form of mercury?

    Mercury has 3 forms: (1) elemental mercury, (2) inorganic salts, and (3) organic compounds. Perhaps the most deadly form of mercury is methylmercury.

    What are 5 common uses of mercury?

    Mercury is used to make thermometers, diffusion pumps, barometers, mercury vapor lamps, mercury switches, pesticides, batteries, dental preparations, antifouling paints, pigments, and catalysts. Many of the salts and organic mercury compounds are important.
