    Exclamation Erionite warning! "New" type of asbestos may blanket ghost towns of the west

    http://openchannel.msnbc.msn.com/_ne...-known-mineral



    At the center of every mesothelioma tumor is a fiber or two of asbestos. But there are more types of "asbestos" than the average person realizes. Not all of the cancer-causing fibrous rocks are called asbestos.

    One is called erionite, and it is found in the USA.

    Nobody realized the danger until recently, when it was found that lung cancer rates skyrocketed in Turkish villages where they carved houses into erionite-laden rock. With horror, the researchers there realized that erionite is also found in the US.

    Erionite-contaminated rock may be used in the creation of dirt and gravel roads near these ghost towns. Drive with the windows up, and go through an automatic car wash before you park in your garage at home.

    .............................


    It may be worth your while to wear protective clothing and masks at some ghost town or mining sites.

    -Removing your clothes, placing them in a garbage bag and immediately laundering them upon returning home (as well as taking a shower!) may just save your life. Spraying your clothing with water before bagging them is a good idea, if possible.

    -Wear rubber boots while at the site, and bag them also before entering your vehicle. Wash them off at home.

    -Wear a dust mask at the site, and remove it last after bagging your clothes and shoes.

    -Touching erionite does not give you cancer, inhaling the particles is where the risk lies. If you touch a dusty object, do not touch your face or wipe your nose until you wash your hands.

    -At home, wear a dust mask again when you open the bag to do the laundry.

    -Don't take your dog to the site, as erionite particles can hitch a ride home on his fur.

    -Do not disturb objects at the town that may raise dust. If you can, visit on a damp day.

    What if I have already been exposed?

    It can take 40-50 years from the time of exposure until the time the cancer appears. If you have been exposed, become vigilant, and monitor yourself for the symptoms. Don't panic. While the outcome is grim for many victims, you can survive it if you catch it soon enough.

    -Inform your doctor of your exposure, so he/she can be aware that you have a significant risk of developing mesothelioma.

    Symptoms

    -They do not appear until the cancer has already developed.

    Most Common

    -Shortness of breath
    -Pleural Effusions
    (excess fluid that accumulates between the pleura, the fluid-filled space that surrounds the lungs.)
    -Chest Pain

    Less Common

    -Weight loss
    -Chronic Cough

    Here is the text of the article:

    By Myron Levin, FairWarning.org

    Mesothelioma, an exceedingly rare and lethal form of cancer, was once thought to be caused only by inhaling asbestos fibers.
    Then in the late 1970s, when astonishing rates of the disease were reported among villagers in central Turkey, studies determined that a different fibrous mineral was the culprit. Erionite was abundant in native soil and stone, and so easy to work with that villagers had used it to build homes.

    In the most devastated communities, known locally as “cancer villages,” mesothelioma rates were off the charts--responsible for 40 percent to 50 percent of all deaths.

    Animal studies showed erionite to be 100 to 800 times more carcinogenic than asbestos and, according to a scientific paper, “almost certainly the most toxic naturally occurring fibrous mineral known.”


    In the U.S., medical journals and news stories presented the Turkish epidemic as a gruesome, but distant, catastrophe. They largely omitted a key fact: Erionite deposits are present scores of sites in at least a dozen western U.S. states.
    Interviews and documents from the 1980s show there was a flicker of interest in assessing the risks in the U.S., but researchers and officials lost interest and moved on to other things.


    The result is that, after three decades, erionite remains a word most Americans—and many environmental officials--have never heard. Amid an expansion of roads, pipelines, power lines, wind and solar farms and recreation sites in remote areas of the West, erionite is unregulated, and federal agencies have failed to alert land-use officials, developers and residents of affected areas so that they might take precautions on their own.


    Uneasy about the long silence, some government officials and scientists are trying to fashion a federal response. Toward that end, a meeting planned next week at the National Institutes of Health, will bring together representatives of the Environmental Protection Agency, the National Institute for Occupational Safety and Health, the Mine Safety and Health Administration, and the U.S. Geological Survey, to discuss potential risks from erionite and other hazardous minerals.
    “We need to be cautious because there’s clear evidence of disease” from mineral fibers, said Dr. Aubrey Miller, a senior medical advisor at the National Institute of Environmental Health Sciences who will chair the meeting.

    “At a minimum, we can begin to start to educate the public and policymakers,” he told FairWarning. “I certainly don’t want to count bodies later.”
    Driving the renewed interest is fear of repeating past government failures to promptly inform the public of potential hazards.

    One case involved Libby, Montana, where asbestos contamination from a mine near the town was blamed for scores of deaths and illnesses among workers and residents. Vermiculite ore tainted by asbestos and mined from about 1920 to 1990 was given to unwary residents for use as insulation and in other building projects. When the EPA arrived on the scene in 1999, it came under scathing criticism for failing to act earlier to inform the community and launch a cleanup.
    Another was the disclosure that road crews in North Dakota, heedless of the danger, had used erionite-tainted gravel to cover hundreds of miles of unpaved roads in the western part of the state, including school bus routes, along with parking lots and recreation sites.
    Erionite is found where volcanic ash and rock have been weathered by alkaline water, Like asbestos, it is harmless until it is disturbed, and the microscopic, needle-like fibers become airborne. And like asbestos, greater and more frequent exposure generally means higher risk.

    No proof has emerged of erionite-related illnesses in North Dakota or other western states, but experts say that is less than reassuring. Mesothelioma usually takes 30 to 50 years to develop, is sometimes mistaken for other cancers, and when identified often is automatically assumed to be asbestos-related.
    In Mexico, a mesothelioma cluster has been reported in a rural area near the border of Zacatecas and Jalisco states. Medical reports say victims had no known exposure to asbestos, but lived on a plain rich in zeolites, the mineral family that includes erionite.
    When Turkish researchers in the 1970s found soaring rates of mesothelioma in the Cappadocia region, they linked it to villagers inhaling dust while farming potatoes and scallions. They soon discovered that residents were also being exposed inside their homes built with erionite-containing stones.
    Research later uncovered a genetic factor. People in the hardest-hit villages had long been shunned by horrified outsiders, leading to inbreeding and magnifying the risk for those with a genetic predisposition to the harmful effects.

    Documents reflect a brief interest in the health implications for the American West.
    In an area of north central Nevada where erionite was present in road dust, researchers from the University of Utah examined chest radiographs from a local hospital, but turned up nothing unusual. But they also published a case report describing a local road construction worker with respiratory disease whose lung biopsy showed fibrous particles “consistent with erionite” An investigation of mesothelioma “in the Intermountain region and exposure relationships would be useful,” they wrote.
    But according to two of the researchers, Dr. William Rom, currently director of the pulmonary division at the New York University School of Medicine, and Dr. Kenneth Casey, now at the University of Cincinnati College of Medicine, their request for a grant from the Institutes of Health was turned down.
    About the same time, with the Defense Department proposing to build a network of “racetracks” to shuttle nuclear MX missiles over a vast area of the Great Basin, opponents seized on the problem of erionite dust. The plan was abandoned, and interest in erionite faded, too.
    It was revived by chance after an official from the U.S. Geological Survey gave a talk at the spring banquet of the University of North Dakota geology department in 2005. He spoke of the need for geologists to be aware of naturally occurring hazards, mentioning erionite. An assistant professor named Nels Forsman piped up: “Hey, we’ve got some of that right here in North Dakota.”
    In the mid-1980s, Forsman, had done a field study in the Killdeer Mountains of western North Dakota for the state geological survey. His 1986 report noted the presence of erionite, but he knew nothing of the events in Turkey and didn’t give it much thought.

    “Nobody in our department had heard anything about it” until the banquet, Forsman told FairWarning.
    But Forsman then alerted the geological survey, which contacted the state health department, which in turn brought in the EPA. Their investigation launched in 2006 revealed that erionite-containing gravel from pits in western North Dakota had been spread over some 300 miles of unpaved roads.
    Air sampling along the gravel roadways and in vehicles, including inside school buses, revealed erionite levels similar to those in some stricken Turkish villages, though at lower concentrations than the most devastated communities. A preliminary health study that included 15 people thought to have high exposure to road gravel found two with pleural plaques, or lung scarring, consistent with inhalation of mineral fibers.

    Part II

    Though the erionite situation quickly erupted into a major story in North Dakota, it drew virtually no media attention outside the state. So complete was the blackout that last December, when Dr. Michele Carbone, a prominent mesothelioma researcher, briefed lung specialists at a national medical meeting in Chicago, it was the first they had heard of it, according to some who attended.
    In response to the discovery, the North Dakota Department of Transportation has banned the use of erionite-containing gravel on state roads. But the western part of the state is in the midst of a gigantic oil boom, bringing a massive increase in truck traffic and road dust that residents say clouds visibility and may be harming crops and human health. Last month the state industrial commission and two of the most affected counties authorized a study of the best ways to reduce road dust.
    Some agencies in other states are taking safety measures, though the efforts have been isolated and piecemeal.
    In eastern Oregon, which has large erionite beds, the state transportation department is conducting a study. The idea is to avoid being “blissfully ignorant” of the locations of erionite or other naturally occurring hazards in future construction and maintenance work, said Matthew Mabey, a research engineer with the Oregon Department of Transportation.
    Oregon Department of Geology and Mineral Industries
    Erionite in rock formations, Rome, Oregon.


    In Montana, where road building crews in the 1960s ripped the top off an erionite-bearing mountain and spread the fill along more than three miles of state highway 323, soil samples have shown erionite levels as high as 20 percent. Highway workers have been directed to use protective suits and respirators when their work involves land disturbance, such as clearing ditches and mowing vegetation.
    Erionite also occurs in rocky outcrops in parts of the Custer National Forest in southeastern Montana and western South Dakota. Forest Service officials have adopted dust control measures, including wetting down helicopter landing spots when fighting wild fires.
    In a joint report, Custer National Forest and Montana officials cited the need for a federal policy to reduce risks from erionite and naturally occurring asbestos.
    Mining is another activity without any rules on erionite exposure. No erionite has been mined in the U.S. for about 30 years, but it is sometimes mixed in with other types of zeolites that are produced at a few mines in the West. According to an EPA report in1987, a producer contacted by the agency stated that its zeolite products “can contain 10 to 30 percent erionite.”
    Most zeolites produced today are of two varieties, chabazite and clinoptilolite. With their ability to trap and filter contaminants, they have been used to purify water and to treat radioactive and other hazardous wastes.
    From its Mud Hills mine in the Mojave Desert in California, Steelhead Specialty Minerals has produced clinoptilolite for cleanup of the tsunami-stricken Fukushima nuclear plant in Japan, said its president Wallace McGregor.

    Along with others in the industry, McGregor said current operators are well aware of erionite, and take pains to avoid it. But “I wouldn’t say there isn’t a trace,” he added. It’s “maybe an overstatement that there are not traces of a little bit of this, and a little bit of that, in a zeolite deposit.”
    Carbone, who will be among those presenting at the meeting at the Institutes of Health, has called for action to prevent and detect mesothelioma cases in North Dakota and other erionite-rich areas.
    Mesothelioma is “a cancer that in most cases can be prevented,” he said in an interview. “We really have the possibility to do something…to prevent cancer in future generations.”

    Talking Warning Warning some day you will die!

    I don't mean to make light of the posts about Erionite here, which are obviously well-meaning. The thing is I live in the desert and when the wind blows here and the dust flies - or just driving down the dirt roads on a regular basis - it would be impossible to comply with all the sterilization techniques recommended in the first post. My wife and I have only been here a couple of years, and we seemed to develop an allergy to the dust, which is probably a form of natural protection. I am nearly 60 now and not real concerned about what I may or may not contract forty years from now. For those who want to take the precautions listed when visiting a ghost town that is fine, but I believe there are far more dangers in some of the chemicals we are exposed to these days, or even GMO food. On a more philosophical note, here is what the great Persian poet Omar wrote six hundred years ago: "Whether among the breakers, by the shore, or out on the open sea, we are all a wreck one day."

    Ah asbestos! The most mislabeled misused term today(in my opinion). There are multiple minerals that have an asbestosis form! Meaning fuzzy needles. The vast majority are not known to cause problems. This is where blanket statements get us trouble. Good to see the report focused on something specific, but what to do?? Lock everyone out because you MIGHT get sick? Already happened in california. Don't remember where exactly, but access to national forest forbidden because of "asbestos" form minerals. Not asbestos specifaclly just another mineral that has that form. So is that what we should expect for any other sites that are deemed "killers" by the government?? Lots of public land already being locked up for other various reasons, is this the MAJOR threat that closes more? I am not trying to discount the possible problems. Just find it kinda funny that they would tell you to "suit up" and wear respirators to go visit the great outdoors. Seems a little backwards to me. I prefer the FRESH mountain air myself!

    This warning is specifically aimed at people visiting mines and ghost towns in the areas where Zeolite mines were active. Those are just a few specific areas.

    Everybody knows you're not supposed to enter a mine, hazards like poison gasses abound, but not many people are aware that even the dust of some specific mines can be toxic. Many photos of the inside of mines end up on this forum; we all know they can be intriguing to wander into "just to take a peek". These mine-explorers I think are the most vulnerable.

    Zeolite and erionite can also be fun to carve your name into: it is soft. It is easy to scrach your name into a hillside or rock formation. Other names may already be on there, and you might want to add yours. I'm just trying to get it out there that doing things like this can be hazardous. Think about what kind of rock formation it is before you explore it and disturb it.

    If a wind storm is picking up, you might want to plan your visit to a ghost town near zeolite formations another day. Awareness may help you, and cannot hurt you.
