Chrysotile is a serpentine mineral belonging to the asbestiform sub-group. It is a material that is manufactured from asbestos. It can be found in Canada, South Africa, Russia and in four states in the U.S. Some controversy has been equated with the production and use of chrysotile asbestos, because it is known that is a carcinogen and the greatest contribution to breast cancer mesothelioma. In fact, due to half of reported cases of mesothelioma have been on the professional and industrial use of asbestos.
The effects of high exposure to asbestos has been recognized in South Africa in 1960. Since then, further studies and research have followed. It is estimated that about 4 people die each year from one million to mesothelioma due to asbestos exposure. Unfortunately, the number is not as accurate because mesothelioma is not easy to diagnose and is often mistaken for another disease.
What is> Mesothelioma?
Mesothelioma is a cancer that can be found in the thoracic (chest) and abdominal cavities. It affects the mesothelium, a protective lining that covers several organs in the body. Mesothelioma is often attributed to exposure to asbestos. It is rare and only affects about 2,000 people in the U.S. each year. It is found more often in men than in women.
The connection between mesothelioma andChrysotile
Chrysotile is a form of asbestos. It has caused some concern because asbestos has been shown to cause cancer in humans and is responsible for many cases of mesothelioma made. However, it can only increase the risk of mesothelioma chrysotile, if it is inhaled and taken up in very large quantities. This is because, as is rolled sheet silicate chrysotile versus other forms, the leaf amphiboles are. Because it is flexible, is less likely to chrysotilelead to cancer if taken in small quantities. It is also not embed itself in the body and can be easily removed.
The same is not true with other forms, such as asbestos, anthophyllite, tremolite, actinolite, amosite and crocidolite. If these forms of asbestos are inhaled, embeds it into the lung tissue and a source of irritation. In future, the irritated tissue cancer. Chrysotile is also different in chemical composition to other forms of asbestos, whichprobably explains to reduce some of their effectiveness.
However, chrysotile can still cause cancer tissue in the lungs to grow with prolonged exposure, but only in very high concentrations of the material. Other forms of asbestos have only a moderate exposure to the risk that increases a person to develop mesothelioma. In fact, many experts agree that asbestos forms of asbestos in the first place among those persons who are exposed to asbestos as part of their experience of sustainableProfession.
The proof of the risk of developing mesothelioma from chrysotile exposure
Although there is a weak link between chrysotile and the risk of mesothelioma, there is a risk, are exposed to tremolite is found in certain chrysotile ore. This exposure represents a potential hazard for people working in chrysotile mines.
A McDonald & McDonald mesothelioma study of chrysotile workers were conducted in 1995 revealed that more workersin certain areas of the mine who were affected. Analysis of lung tissue in post-mortem cases also showed that the workers in the field had 4-fold amount of tremolite in the lungs compared to workers in other fields. This suggests that it is not chrysotile, which causes mesothelioma, but the workers tremolite development. The study also found that the mesothelioma cases are the result of prolonged high exposures for many decades were.
Apart from tremolite,Crocidolite also significantly increases the risk of mesothelioma compared to amosite. This has been demonstrated repeatedly and in many studies.
What does the future hold for chrysotile?
All asbestiform materials are highly regulated by law in many countries including the United States and Canada. In fact, it is a significant decline in the exposure of humans to chrysotile because legislation does mandate that chrysotile fibers are at a level very low risk of being updatednegative impact on health, particularly the risk of mesothelioma. It's not the fact that chrysotile may pose serious health risks, despite industry all the time that the exposure of people are guaranteed, is reduced to a minimum. Currently, chrysotile is mined is still produced the only form of asbestos commercial.
