Mesothelioma lung cancer is usually associated with asbestos exposure. In fact there are many other risk factors that cause mesothelioma cancer. One of them is the erionite. Erionite is a naturally occurring fibrous mineral that belongs to a group of minerals called zeolites. Zeolites are hydrated aluminosilicates of the alkaline and alkaline-earth metals.
Erionite was used in the past as a noble metal-impregnated catalyst in a hydrocarbon-cracking process. It was studied for use in fertilizers and to control odors in livestock production, because of its ability to selectively adsorb molecules from air or liquids. In many countries erionite blocks were used (and may be are still used) as building material or in stucco pastes and whitewash.
Erionite was mentioned for the first time as a mesothelioma lung cancer risk factor in 1975, when Turkish government presented a study that uncovered a high incidence of a rare malignant mesothelioma in lung tissues of people in certain small villages in the Cappadocia area in Turkey’s central mountainous region. In two small villages the mesothelioma lung cancer accounted for 43% of the deaths during 23 years period of study. Erionite fibers were found in biopsies of lungs of the mesothelioma cancer afflicted people. Comparing this to a 9.7% rate of death from this disease among asbestos insulation installers shows how anomalous this condition was.
Further studies showed erionite causes similar diseases in laboratory animals. When researchers at Mt. Sinai Hospital injected rats with the same dosage of erionite that they used for asbestos, the rats didn’t live long enough to get mesothelioma cancer. At a much-reduced dose, the rats did get cancer. Erionite is probably the most toxic known mineral - a milligram of fibers in the lungs is lethal.
Today erionite is considered so hazardous that the EPA requires any one who intends to manufacture, import or process any article containing erionite to notify the E.P.A. 90 days in advance. This gives the EPA a chance to review, limit or prohibit that activity. Read the rest of article here..

Erionite is no longer mined or marketed for commercial purposes. Although other natural zeolites have many commercial uses (pet litter, soil conditioners, animal feed, waste-water treatment, gas absorbents, etc.) So potential occupational exposure to erionite occurs during the production and mining of other zeolites.
And there are questions:
Are there other mineralogical hazards like erionite and asbestos?
Should we expected mesothelioma lung cancer increases not only from asbestos exposure after another 20 - 30 years?
Asbestos exposure is by far one of the most common causes of mesothelioma. Over 50% of the patients have a history of asbestos exposure. This exposure could occur while directly handling the fibrous material, or it could occur through just environmental exposure.
There are numerous documented cases where patients contracted the disease due to living close to the asbestos mines or by coming in contact with asbestos when some of the fibers became airborne. Persons most commonly afflicted include shipyard workers, construction workers, automobile mechanics (particularly those working on brake linings), insulation workers, pipe and heater installation and flooring workers and roofers.
Also, for those who have had asbestos exposure and who smoke, the risk becomes exaggerated. Studies show that asbestos workers who also smoke are 55 times more likely to die of mesothelioma than nonsmokers without asbestos exposure.
Erionite
Erionite is a mineral that has a long, thin rod-like amphiboles structure. Exposure to this mineral has been associated with increased incidence of mesothelioma. Erionite exposure has a high mortality rate due to mesothelioma in Anatolia, Turkey.
Exposure to asbestos is the primary cause for malignant mesothelioma in most patients. If you or a loved one has been exposed to asbestos, then you are at risk. There is no minimum level of exposure that is deemed safe. Insure that during your routine health care, you advise your doctor of previous asbestos exposure, particularly if you experience any chest pressure, shortness of breath, chest pain or coughing. While these symptoms do not indicate the presence of the disease, they are the most common symptoms and should be further investigated if you have had asbestos exposure.
Thousands of people die of the mesothelioma. The asbestos fibers into the air to cause this deadly disease. The fibers remain in the air, and when they are in the lungs, which cause the disease.
Almost everyone is today by asbestos without protection, but the risk is different from one person to another. It is not necessary, if you are the least exposure to the level of development of this disease is less, as the characteristic of the disease is very strange. But it is quite clear that those who asbestos over a long period of time have a greater chance of this disease.
If the nature of your work with asbestos mining or milling, shipbuilding professionals who work on the insulation, etc., then you are in a big risk for this dangerous disease, mesothelioma. The seats are hard, affected by this disease are dangererous in the Cappadocia region of Turkey, because there are many workers in the construction, which in this area live. Many people in the United States have also against this disease.
Even the genetics plays a role. Because of a few people who come into contact with asbestos for years not against this disease. The genetic factors have helped the disease to resist.
Stay on the distance of asbestos mines and not of products in connection with asbestos, if you want to be.
