Pollution of water by barium and other chemical substances. This fact sheet is one of a series of summaries about hazardous substances and their health effects. This information is important because this substance may harm you. The effects of hazardous substances affected depending on the dose, duration, how you are exposed, personal traits and habits, and whether other chemicals are present.

Summary: Exposure to barium occurs primarily in the workplace or from drinking contaminated water. Barium swallow high levels can cause problems with liver, stomach, liver, kidneys, and other organs. This chemical has been found at least 649 of the 1416 National Priorities List sites identified by the Environmental Protection Agency.

What is barium?

Barium is a silver-white metal - silver found in nature. It occurs combined with other chemicals such as sulfur or carbon and oxygen. This combination is called a compound. Barium compounds can also be produced by industry.

Pollution of water by barium compounds which are used by oil and gas industries to make drilling mud. Drilling mud is useful to facilitate drilling through rock by keeping the drill bit lubricated. Drilling mud is also used to make paint, bricks, tiles, glass, and rubber.

Barium compounds (barium sulfate) by the doctor is sometimes used to conduct medical tests / health and to take x-rays of the abdomen.

What happens to barium when it enters the environment?

* Barium into the air during mining, refining. And barium compounds produced from burning coal and oil.
* Some barium compounds dissolve in water and can be found in the lakes, and on the river - the river.
* Barium is found in most soils and foods at low levels.
* Fish and aquatic organisms can accumulate barium.

How could I be exposed to barium?


* The level of respiration is very low in air, drinking water, and also food - the food.
* A higher respiration rate in the air and when working in industries that make or also use barium compounds.
* Drinking water from natural sources that contain high levels of barium.
* Breathing air near barium or processing plant mines.

How can barium affect my health?

Health effects of barium compounds different way and it depends on how well the compounds soluble in water. Barium compounds are not soluble in water well in general are not dangerous and is often used by physicians for the purpose of health / medical.

Pollution of water by barium compounds that dissolve well in water can cause adverse human health effects. High levels of soluble barium swallow compounds in water well over the short term has resulted in

* Difficulty in breathing
* Increased blood pressure
* Changes in heart rate
* Stomach irritation
* Swelling of the brain
* Muscle weakness
* Damage to the liver, kidneys, heart, and spleen.

We do not know the effect on the low levels of barium swallow in the long run. Animal studies have found that increased blood pressure and changes in the heart after barium swallow in a long time. We do not know the effect of barium from breathing or touching it.

How likely is barium to cause cancer

Department of Health and Human Services, the International Agency for Research on Cancer, and the Environmental Protection Agency (EPA) / Environmental Protection Agency, has not been grouped barium can cause human cancer.

Barium has not be grouped can cause cancer because there are no studies in people and two animal studies available are insufficient to determine whether the barium does not cause cancer.

Is there a medical test / health to show whether we are exposed to barium?

There are no medical tests / health routine to indicate whether you have been exposed to barium. However, doctors can measure barium in the blood, bone, urine, and feces, using highly complex equipment. Because of the complexity of the test, the test is usually done only for cases of severe barium poisoning and for medical research.

Does the central government provide recommendations to protect human health?

EPA allows 2 parts of barium per million parts of drinking water (2 ppm). EPA requires that the disposal or leakage into the environment of the 10 kilo grams or more of barium cyanide has been reported.

Occupational Safety and Health Administration (OSHA) / Occupational Safety and Health Administration, National Institute for Occupational Safety and Health (NIOSH) / National Institute for Occupational Safety and Health, and the American Conference of Governmental Industrial Hygienists (ACGIH) / American Conference of Government Industrial hygienists and has set the occupational exposure limit of 0.5 milligrams of soluble barium compounds per cubic meter of air (0.5 mg/m3) for 8-hour workday, 40-hour work week.

OSHA exposure limit for barium sulfate dust in air is 5 to 15 milligrams of barium per cubic meter of air (5-15 mg/m3)

NIOSH recommends that the current level of 50 mg/m3 is considered hazardous to life and health. This is the level of exposure of barium that may cause permanent health problems or death.

Concise dictionary

Are induced cancer: Ability to cause cancer. Ingesting: Taking food or drink into your body. Long term: Hold for one year or more. Milligrams (mg): One per thousand grams. PPM: Parts per million / parts per million. Short Term: Hold up to 14 days or less. Soluble: Also dissolve in the liquid.
