Asbestos Contaminates Canadian University Labs

Asbestos Contaminates Canadian University Labs


Fear and frustration best describes emotions felt by University of Toronto college and students once they assert administration delayed notification that amphibole contaminated a number of the university’s science labs.

“The emotional expertise is actually devastating,” aforementioned physiology ANd medication prof Adria Giacca in an interview with blood count News.

Another prof, United Nations agency didn’t wish to be known, told the world and Mail: “I’ve lost confidence, and my work individuals have lost confidence…[It] perpetuates worry whenever you see mud, you currently worry. Am I about to get cancer twenty years from now?”

Asbestos is that the leading reason for carcinoma, AN incurable cancer whose symptoms don’t seem till 20-50 years once amphibole exposure.

A maintenance one that rumored losing stay over the difficulty, once sweeping the affected labs many times, aforementioned officers ought to have hep him of the potential exposure to amphibole.

Faculty and students say they'd no plan their labs were contaminated with the deadly substance till the university administration issued notification a month once check results showed amphibole mud in 3 labs.

University mistreated with Union Grievance

The union that represents teaching assistants and contract college already filed a grievance against the university, claiming the college desecrated the activity and Safety Act.

CUPE native 3902 cites reports from union members United Nations agency say they continued  to figure while not notification despite 3 documented cases of amphibole leaks within the building wherever they were operating.

College Renovation Underway

The incident comes on the heels of a $190-million renovation and nuisance abatement project across 3 campuses.

The problems occurred within the university’s St. George bioscience Building and diode to what students describe as “unusual amounts of white mud coating their work instrumentation, papers, laptops, benches and also the floor” as early as Gregorian calendar month 2016.

Farshad Azimi, a scholar student, remembers “a ton of white powder” within the hallways outside the work he's employed in as early as December. He says he thought it had one thing to try to to with the development however didn’t hear something concerning amphibole till March eight.

“What we tend to were afraid by was the very fact that this was unbroken quiet, as a result of it happened on different floors, and also the info wasn't shared,” Azimi aforementioned.

Scott Mabury, vice chairman of university operations, acknowledged that communication concerning the difficulty has been a challenge.

“I acknowledge and acknowledge [students’] concern. Our primary interest is their safety,” Mabury aforementioned.

Those exposed to the deadly microscopic fibers have sensible reason to feel unsettled.

If someone inhales amphibole fibers, tumors could type round the lodged threads and cause the event of carcinoma.

Multiple Positive Tests Results for Asbestos

Tests results on February. one showed contamination in 3 separate labs. additional analysis showed amphibole gift within the labs on February. twenty four and day. Overall, the unhealthful substance perforate 5 separate rooms.

In the aftermath, university officers discharged the old contractor once learning of 3 specific incidents wherever amphibole fibers leaked out of secured areas:

  • A worker drilled a hole in the wall leaving a pile of asbestos dust on the floor.
  • Fibers leaked from a containment area that wasn’t sealed properly.
  • Air pressure forced asbestos-containing dust out of a service shaft where workers were present.

The science building is fifty years recent. Construction comes throughout that amount used prolific amounts of floor and ceiling tiles that contain the fatal material that was publicised for its fireplace retardent properties.

University officers closed 2 labs once perennial tests showed positive results for amphibole contamination. Since then, officers issued a written statement explaining the complete bioscience building was “safe for general occupancy” supported results of over two hundred air samples taken in and round the building over the past 2 months.

University Officials Promise Complete Abatement

The school’s statement enclosed a promise for a comprehensive review to analyze the supply of amphibole contamination.

Giacca remains unconvinced  and says she needs foolproof documentation that her work is safe, citing that it tested positive for amphibole solely one or two weeks past. whereas her work has since been reopened, she maintains her disappointment over university communication concerning the contamination.

Mabury defended the university’s handling of true stating, “All needed communication was done.” He explicit  that college United Nations agency worked within the affected labs received notification and notes were placed on doors.

The university continues to watch air quality within the building, posting the results on their web site on a daily basis. Administration officers report the college has not been needed to require any longer measures supported superintendence by the Department of Labour that sent representatives to go to the positioning 3 times.

Expected Canadian Asbestos Ban Next Year

This incident comes at a vital time in Canada’s history.

Public awareness concerning the risks of amphibole is at AN all time high because the nation appearance to AN expected amphibole ban by 2018. The prohibition includes merchandise containing amphibole likewise as imports with the cancer material. The ban might be merchandise already factory-made.

Canada would be a part of fifty six different countries, together with the U.K., Germany, France, and Japan, that already placed a permanent moratorium on the verified cancer-causing mineral. whereas it’s heavily regulated within the U.S., lawmakers haven't prohibited the substance.

Erionite Exposure and Mesothelioma Cancer

Erionite Exposure and Mesothelioma Cancer

Although less well known than the mineral asbestos, erionite is that when exposing natural carcinogens in the long term and repeatedly can cause mesothelioma, lung cancer and other deadly diseases. Exposure to erionite more important to the environment. A person affected by mesothelioma from exposure to erionite usually stay near the mineral deposits in significant numbers.
Through laboratory tests on animals show that exposure to erionite has been shown to have a higher risk of developing cancer such as mesothelioma lung than other minerals that were tested included asbestos. Mesothelioma is caused by exposure to light erionite more rapidly than asbestos exposure.

Exposure to Erionite

Erionite is asbestiform is a natural mineral from guning high fibrous volcanic mineral with similar properties to asbestos. Zeolite mineral erionite is like a serpentine or amphibole asbestos. Erionite not in ijijnkan in the United States in commercial use such a wide variety of other asbestos minerals.

Usually the trace amounts of erionite have been found in other zeolite products such as water softeners or water purification systems. Nevertheless exposure to erionite more from mines other zeolite or through exposure to the natural environment. Traces of erionite in the zeolite products may cause exposure to low levels, although demikain is not known whether this product can cause mesothelioma.

If generally associated with asbestos exposure in which a person engaged in the manufacture, handling or installation of asbestos products. Then came the repeated inhalation of asbestos particles that have the potential of developing cancer mesothelioma and other asbestos cancers. However, upon exposure to erionite, the majority caused by environmental exposure associated where a person lives near or around precipitate erionite.

Known throughout the world there are deposits of erionite in Germany, New Zealand, Russia, Japan, Kenya, Turkey and Italy. In the United States most of the erionite deposits located in the West, especially in Oregon, Arizona, Nevada, California, Wyoming, North Dakota and Utah. 

The high rate of mesothelioma

A small village in Turkey named Tuzkoy have erionite exposure levels were very high for the environment and can lead to the growth of malignant mesothelioma, lung cancer and other lung diseases. With the excessive concentration of erionite deposits in the area around Tuzkoy, the exposure comes from inhaling the fibrous mineral. Erionite particles occurs naturally through the dust surrounding air.
A small portion of the villagers have been using boxes of erionite as a cooler to store food. Exposure to erionite particles can contribute to a safe stored. However, most cases of mesothelioma in Tuzkoy is mainly due to exposure to the environment than the food storage boxes.
"City of Cancer" has a fairly high rate of mortality due to pleural and peritoneal mesothelioma is caused almost seventy times that of the average annual mortality. Studies have shown that erionite deposits adjacent to the region cause.
Compared with asbestos still little is known about erionite exposure. Many health organizations around the world are aggressively studying the health effects of this mineral
As a natural carcinogens, erionite effect to someone through a process similar to asbestos. Through prolonged exposure and inhalation of breath, erionite particles settle specifically into the lung or in general into the mesothelium, the lining of internal organs. Finally erionite particles embedded trigger carcinogenesis or transformation of normal cells into cancer cells.
Moreover, the incubation period of erionite in the lungs and mesothelium similar to asbestos, ie from 10-20 years. Symptoms of mesothelioma caused by erionite also similar to asbestos such as shortness of breath, pain in the chest wall and weight loss.
Research has shown that low-level exposure to erionite levels have a higher risk of cancer than the growth of mineral asbestos exposure. Basically, it takes the number of erionite particles far smaller than asbestos to cause cancer.
Whether it is caused by erionite or asbestos, which definitely mesothelioma disease is destroyed. Since the discovery of the relationship between exposure to erionite, and the incidence of mesothelioma is high, many in the scientific and medical fields start doing in-depth research. Mineral asbestos for commercial applications has indeed been used, but the impact on the environment exposure to erionite is more deadly than at work. As in Tuzkoy, breathing the air in the surrounding environment erionite deposits can cause mesothelioma.

What are the risk factors of mesothelioma cancer?

 What are the risk factors of mesothelioma cancer?

There are several risk factors that increase the likelihood that a person's body will develop mesothelioma. The main risk factor is exposure to asbestos. Exposure to highly hazardous substances can significantly increase the chances of contracting the disease. Smoking has no direct causal connection with mesothelioma, but can significantly increase the risk and exacerbate the chances of developing the disease. Other causes of secondary factors include exposure to radiation, zeolite, simian virus 40 (SV40) and erionite. Will be discussed each of the risk factors detailed in the information link below.
factors of mesothelioma cancer
Asbestos Exposure >>
Exposure to asbestos is the main risk factors for mesothelioma. Asbestos is an insulating material consisting of a magnesium-silicate mineral fibers. Asbestos is favored by builders and contractors for many years for the low thermal conductivity and melt-resistant and resistant to burn. Because researchers have identified a further relationship between mesothelioma and asbestos exposure, asbestos material began rarely used. Prior to this study revealed, millions of Americans have suffered a serious exposure to this harmful substance asbestos.

Smoking and Mesothelioma >>

Smoking alone is not associated with mesothelioma, but smokers who are exposed to asbestos have a much higher chance of developing asbestos lung cancer (as much as 50-90 percent higher) and as much as double the risk of developing 

Secondary Risk Factors Mesothelioma

radiation >> 
Thorium dioxide (Thorotrast), a substance used in x-ray tests in the past has been reported to have relationships that cause pleural mesothelioma and peritoneal mesothelioma. Thorotrast the use has been discontinued for many years because of this discovery.

zeolite >> 

Some cases of mesothelioma in the region Anatoli in Turkey has been associated with zeolite. Silica-based minerals that are chemically similar to asbestos found in the ground there.

Simian virus 40 (SV40) >>

Some scientists have discovered simian virus 40 (SV30) in mesothelioma cells of humans and have been able to create mesothelioma in animals with virusni. The relationship between this virus and mesothelioma is still unclear. However further research is being conducted to gain clarity about the potential causes of this relationship.

Exposure to erionite >>

Erionite is a naturally occurring mineral that has properties very similar to asbestos. There are several documented cases of mesothelioma in people living near the disposal erionite.

Carbon nanotubes >>

Researchers continue to evaluate the exposure of nanotubes as a possible risk factor for mesothelioma penyabab although scientists do not yet expressed his concern in this regard.Source:

Radiation and Cancer Mesothelioma

Radiation and Cancer Mesothelioma

Within a few decades it is assumed that the only cause of mesothelioma is exposure to asbestos. While this asbestos is responsible for most cases of mesothelioma cancer. But gradually the more chances there are several other risk factors for this disease.
Atomic Radiation and Mesothelioma

Atomic Radiation and Mesothelioma

Across the world, a number of cases of mesothelioma with no causal connection has been diagnosed with asbestos. As a fact, a study of 1980 patients (McDonald and McDonald) in the US and Canada established that the number between 25 percent to 33 percent of all cases are not related to asbestos exposure. The doctor who discovered initially at a loss to explain. However, with some in-depth research and studies, some scientists and medical professionals can determine that some patients with pleural mesothelioma have other similar factors that exposure radias.

Radiation treatment, X-ray, and Mesothelioma 

Several dozen cases of mesothelioma with radiation therapy for Hodgkin's disease has been found. A 2005 study entitled "Clinical Course of Thoracic Cancers in Hodgkin's Disease Survivors" (P. Das, AK Ng, MA Stevenson, and PM Mauch) exactly establish that patients with Hodgkin's disease who were treated with radiation therapy have a higher risk of disease mesothelioma.
Specifically, this study followed 33 patients with Hodgkin hospitalized Harvard and has grown mesothelioma lung cancer small cell. Of the participating patients, 88 percent had a history of radiotherapy to the thorax as a treatment for their disease. Some patients have suffered from breast cancer in just over a year after being treated for Hodgkin's disease. Whereas other patients contracted Hodgkin mesotheliokma after more than two decades later. Like most patients with mesothelioma, most patients diagnosed with mesothelioma when it reached stage III or IV and the prognosis is very difficult. The survival rate average is only 9 months.
In some cases, peritoneal mesothelioma has also been associated with radiation therapy for breast cancer or other cancers that do to the chest area
Other studies have found a relationship between mesothelioma and thorium dioxide, which is a radioactive substance that is used in conjunction with conventional x-ray to diagnose certain conditions. Thorium dioxide is widely used from the 1920s until the 1950s

Atomic Radiation and Mesothelioma  

In 1995, the first case has been diagnosed with mesothelioma and believed to be associated with the incidence of the atomic bomb on Nagasaki. A report in this case, written by Masami Mizuki, Keiko Yukishige, Yasuharu Abe, and Tomiyasu Tsuda published in the journal Respirology in September 1997. They argue that the combination of exposure to atomic radiation and asbestos (patient worked for 2 years as a shipbuilder in a ammunition factory) was associated with an increased incidence of mesothelioma.
The doctors who wrote the study found, "If the pleural thickening or pleural effusion was found in the atomic bomb survivors, malignant mesothelioma should be considered as an option in the differential diagnosis, even though the atomic bomb attacks several decades ago."
Atomic Energy workers and Mesothelioma
It seems that there is a potential connection to the occurrence of mesothelioma in place with radiation exposure. Over the past few decades, few people currently or previously worked on atomic energy plant have been diagnosed with a rare cancer. In this case thought to be caused by constant exposure to radiation in low levels. (Ionizing radiation: A risk factor for cancer; JE Goodman et al, 2009) It is important to note is the authors concluded that given the low rate of mesothelioma in the general population as well as an increased risk of disease on individuals exposed to radiation, including those working in atomic power plants.

Relationship Between Radiation and Mesothelioma

Knowing about the relationship between radiation and mesothelioma is one of the measures for speeding up diagnosis and saved many people who have been identified as potential victims of mesothelioma. Anyone who has been exposed to radiation in any form, either regularly in the workplace or through x-ray or through therapy for other cancers chest, should always tell their doctor about medical history and history of work despite the radiation exposure occurred a few years earlier. Therefore, if the symptoms include chest pain, shortness of breath, and coughing can be determined relationship with a medical history and a history of the patient work can then be made the correct diagnosis and treatment of mesothelioma begin as soon as possible.


Smoking and Mesothelioma

Smoking and Mesothelioma

It has long been known that smoking is harmful to one's health. Smoking causes a sharp increase in cases of mesothelioma lung cancer in smokers. But smokers who had been exposed to asbestos carries higher risk of developing the disease even more serious is that malignant mesothelioma cancer that affects the lining of the lungs (pleural mesothelioma), heart (pericardial mesothelioma), or abdomen (peritoneal mesothelioma) and difficult to treat.
Smoking and Mesothelioma

Exposure to asbestos has been identified as the main cause of mesothelioma cancer. This disease occurs when a person inhales asbestos fibers are sharp and then lodged in the lungs. Smoking, according to the Centers for Disease Control can weaken the lungs and decrease the body's ability to eliminate asbestos fibers. Furthermore, cigarette smoke irritates the airways and causes them to produce more mucus which in turn block the airways in removing the fiber.
According to various studies that have been done throughout the last two decades, while this smoke alone did not cause mesothelioma. Smokers who are exposed to asbestos at risk about 50 to 84 times more likely to develop lung cancer asbestos. And experts agree the opinion that smokers are at least twice as likely to develop mesothelioma in the body.
Mesothelioma risk factor is higher for those who had suffered from a severe disease who have not Asbestosis is a disease associated with asbestos, but still manageable. With smoking one pack a day for patients with asbestosis, the higher the chance of developing aggressive cancer. Therefore, those who have suffered from asbestosis must quit smoking. According to studies conducted by the National Cancer Institute states that stopping smoking can reduce by 50 percent the risk of mesothelioma diagnosed in about five years since quitting smoking. Figures are encouraging for smokers with asbestos disease early.
Smokers who have been exposed to asbestos and have not quit smoking, it must be willing to perform a routine medical examination to determine the health of their lungs. Tests to monitor the formation of asbestos cancer mesothelioma, for example such as chest x-ray or pulmonary function test. Moreover, it may also be required simple blood test known as a test ®Mesomark the smokers who suffered exposure to asbestos to detect the presence of mesothelioma.

Mesothelioma and Virus Simian 40 (SV40)

Mesothelioma and Virus Simian 40 (SV40) 

Malignant mesothelioma has been linked to asbestos exposure. The end of this century thousands of cases of the disease found in individuals who work regularly with toxic minerals in a variety of different jobs. But nevertheless report that was released about 30 years ago by McDonald and McDonald determined that about 25-33 percent of all cases of mesothelioma cancer diagnosis does not have a definite relationship with asbestos exposure. A person who has been diagnosed with mesothelioma cancer never any contact with asbestos or asbestos-containing material.

Virus Simian 40 (SV40)

For years researchers have found some other potential causes for the cause of the growth of mesothelioma. One of mesothelioma patients may be exposed to Simian Virus 40 (SV40).

what it SV40?

SV40 is a virus that was first discovered in 1960. The virus is found in the kidney cells of rhesus monkeys. It causes kidney disease and certain cancers in the monkey population. The virus also attacks the specific tumor suppressor gene and cell death.
Simian Virus 40 to the attention of the American public when it is certain that the kidney cells of rhesus monkeys the same one used in the manufacture of polio vaccines are administered to humans. This vaccine has been used from 1958 until 1963 and was given to nearly 100 million Americans. There is a sizeable number of vaccines contaminated with Simian Virus 40 and given to humans during that time period. Although exact figures are not recorded how many doses of virus contamination is given, but an estimated 10 to 30 million doses.

SV40 and Mesothelioma

Since the discovery of Simian virus 40 in millions of doses of polio vaccine, researchers have been exploring the relationship between the virus and the development of cancer in humans. Several studies have found that SV40 is present in many people diagnosed with mesothelioma disease.

A study led by Dr. Michele Carbone mesothelioma is one of the leading specialists in the US, established that more than half (about 54%) of all cases of malignant mesothelioma cancer have been infected with SV40 (Carbone, M. "Simian virus 40 and human tumors: It is time to study mechanisms. "). But they did not find the SV40 contamination in other types of lung cancer. This reinforces the finding that there is a link between SV40 and asbestos cancer, but there is no full proof that only the SV40 might be causing mesothelioma. The doctor gave the hypothesis that exposure to asbestos or immunosuppression may also be involved in this case.

A similar study conducted in 2008 at the Cancer Research Center of Hawaii and the Department of Pathology, University of Hawaii, concluded that about 60 percent of intracardiac injected hamsters with Simian Virus 40 died from mesothelioma. However a significant role SV40 against malignant mesothelioma in humans remains debatable (Rivera et al, "The Relationship between Simian Virus 40 and Mesothelioma"). Conclusion brevity authors report: "There is sufficient evidence on the relationship between simian virus 40 alone or jointly asbestos as a trigger for malignant mesothelioma. However, it is still not enough to speculate about the contribution of simian virus 40 with the overall incidence of pleural mesothelioma (mesothelioma cavity chest)."

Additional study noted that the combination of the presence of SV40 and asbestos exposure occur very frequently in improving development opportunities mesothelioma. In a 2005 report by a number of doctors and scientists Italy (Cristaudo et al, "SV40 enhances the Risk of Malignant Mesothelioma Among People Exposed to Asbestos: A Molecular Epidemiologic Case-Control Study"), the authors hypothesize that the SV40 contributes to cancer development only as an additional factor and not a direct cause.

More importantly, the study determined that "the detection of SV40 between groups of individuals exposed to asbestos could represent a useful marker for identifying those at high risk for MM (Malignant Mesothelioma - malignant mesothelioma). Subgroup of high-risk individuals can be monitored for early detection and the possibility of curative surgical excision ".

Some doctors are constantly looking for better ways to diagnose mesothelioma at an earlier stage, karenan identify high-risk individuals such as this equates to save many lives.


Zeolites and Mesothelioma Cancer

Zeolites and Mesothelioma Cancer

Mesothelioma and asbestos exposure has long been linked hubungkankan. Since the early days of the Holy Roman Empire had noted that slaves who worked in asbestos mines have lung problems are severe and died at an early age. However, in recent decades it has become apparent that there are other potential causes for the development of a rare form of cancer.

Zeolites and Mesothelioma Cancer
A study conducted by McDonald and McDonald in 1980 showed that About a 25-33 percent of all cases of mesothelioma cancer does not have anything to do with exposure to asbestos. However, in research prefix found some other specific cause. One of them is the exposure of the zeolite.

What zeolites?

Known in scientific terms as alkali hydrated aluminum silicate. Zeolite is a mineral group that contains most of hydrated aluminum and silicon compounds. Their common names include 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 materials), textile printing materials, detergents, and as purifying water and air.
Zeolites have also been used in several areas of health, among others as a supplement to a hangover and an adjuvant therapy for various cancers (FDA did not approve of this treatment). But there is still a lack of data supporting the efficacy of the effectiveness of zeolite and no conclusion as to whether zeolite secure. As a mineral that has a systemic effect on the body, zeolite also remains unclear to this day and requires further research.

Zeolite relationship with mesothelioma  

It has become clear, however, that zeolite dust exposure is associated with an increased risk of development of malignant mesothelioma (malignant mesothelioma). Simply to say zeolites are carcinogenic when inhaled. As a matter of International Agency for Research on Cancer placing the zeolite in the list of groups 1. Categorization inidiberikan carcinogens when there is sufficient evidence regarding carcinogenicity in humans causes mesothelioma.Erionite zeolite is a form of fiber that is clearly associated with mesothelioma epidemic in villages Anatolian Plateau in Turkey. In the village local volcanic tuff filled with zeolite toxic fibers. A report on the epidemic published in the 2006 edition of March 15 Journal of the National Cancer Institute.
Doctors in Turkey initiated a study during the 23 years that followed 891 men and women living in three villages in different Turkish Cappadocia region. Villagers had been exposed to erionite. The third village used as a village controlled. During the study which started from 1979 to 2003 as many as 372 people have died. Of the deaths are known to many as 119 people stricken with mesothelioma cancer and died from the disease or complications of the disease. In the two villages where the population is exposed to the toxic mineral known deaths from pleural mesothelioma amounted to 44.5 percent. While in the third village just happened two deaths caused by mesothelioma, and even then it is known that the two of them when they are born not from the village controlled.
Data analysts, including from Harvard professors, namely Philippe Grandjean, MD, Ph.D., determines the result of mesothelioma in the two events. The village is filled with erionite occurs 200-700 cases per 100,000 people annually. In the village there are only controlled 10 cases per 100,000 people. Therefore, the conclusion is that long-term exposure to erionite is responsible for a very high incidence of the cancer cases of asbestos in certain villages of Cappadocia in the Anatolian Plateau.
After the study is completed, the authors suggest that local authorities were concentrating on ways to prevent exposure to the environment from harmful zeolite fibers in the hopes of lowering the risk population for developing the disease mesothelioma.
The precipitate natural erionite have been found in several western US states, especially Arizona, Nevada, Utah, Oregon, North Dakota, South Dakota, and Montana. A report on ereonite / zeolite in the US (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) noted that residents of the area known as the "Intermountain West" may be exposed to fibrous zeolite from wind gusts and therefore vulnerable to the development of mesothelioma. The state of North Dakota is currently conducting studies related to erionite exposure areas are known to have this vast mountain.
