Zeolites and Mesothelioma Cancer
Mesothelioma and asbestos exposure has long been linked. Since the early days of the Holy Roman Empire has been noted that the slaves who worked in asbestos mines have lung problems are severe, and died at an early age. But in recent decades it has become clear that there are other potential causes for the development of a rare form of cancer.
A study conducted by McDonald and McDonald in 1980 showed that About a 25-33 per cent of all mesothelioma cancer cases have no connection whatsoever with asbestos exposure. However, the study found leading some other specific causes. One is the exposure of the zeolite.
What is zeolite?
Known in scientific terms as alkali aluminum silicate hydrate. Zeolites are a group of minerals that contain most of the hydrated aluminum and silicon compounds. Their common name among others Clinoptilolite, Erionite, Phillipsite, and Mordenite. They are found in volcanic rock and ash, and is sometimes used as an additive in animal feed. Because of their porous structure, zeolites can be used as an absorbent (absorbent material), textile printing materials, detergents, and as purifying water and air.
Zeolites have also been used in several medical fields, among others, as a supplement to get drunk and auxiliary therapy for various types of cancer (not FDA approved this treatment). But there is still a lack of data supporting the efficacy of the effectiveness of zeolite and no conclusions about whether the zeolite is safe. As a mineral that has a systemic effect on the body, Zeolite also remains unclear to date and requires further research.
Relationship zeolites with mesothelioma
It is clear that somehow the zeolite dust exposure was associated with an increased risk of developing malignant mesothelioma (malignant mesothelioma). In simple terms it can be said zeolite is carcinogenic when inhaled. As a fact, the International Agency for Research on Cancer puts zeolites in the list of Group 1 carcinogen. Inidiberikan categorization when there is sufficient evidence of carcinogenic properties in humans causes of mesothelioma.
Erionite is a form of zeolite fibers which are clearly associated with an epidemic of mesothelioma in villages in the Anatolian Plateau of Turkey. In the village the local volcanic tufa filled with toxic zeolite fibers. A report on the epidemic of 2006 published in the March 15 Journal of the National Cancer Institute.
Doctors in Turkey began the study during the 23 years that followed 891 men and women living in three villages of different regions in Turkey's Cappadocia. Residents of two villages have been exposed to erionite. The third village is used as a control village. During the study starting from 1979 until 2003 as many as 372 people have died. Of the number who died is known to as many as 119 people stricken with mesothelioma cancer and die from the disease or complications of the disease as well. In two villages where the population is exposed to the toxic mineral known deaths from pleural mesothelioma by 44.5 percent. Whereas in the third village only 2 deaths caused by mesothelioma, and even then they both know that when they are born not from a controlled villages.
Analyzer data, including from the Harvard professor Philippe Grandjean, MD, Ph.D., to determine due to mesothelioma in two events. Erionite villages filled with 200-700 cases occur per 100,000 people annually. In the village there were only 10 cases controlled every 100,000 people. Therefore, the conclusion is that long term exposure to erionite was responsible for a very high incidence of asbestos cancer cases in certain villages of Cappadocia in Anatolia Plateau.
After the study was complete, the authors suggest that local authorities were concentrating on ways to prevent exposure to hazardous environments of zeolite fibers with the hope of lowering the risk population for developing the disease mesothelioma.
Natural sediment erionite has been found in several western U.S. states, especially Arizona, Nevada, Utah, Oregon, North Dakota, South Dakota, and Montana. A report on ereonite / zeolite in the U.S. (Rom, WN, KR Casey, WT Parry, CH Mjaatvedt and F. Moatamed. 1983. Health implications of natural fibrous zeolites for the Intermountain West. Environ Res 30 (1): 1 - 8) notes that local residents are known as the "Intermountain West" may be exposed to fibrous zeolite from wind gusts and therefore susceptible to the development of mesothelioma. The state of North Dakota is currently conducting a study related to exposure to erionite areas known to have these vast mountains.
