How asbestos causes the resources of mesothelioma (article)

Asbestos refers to a group of six fibrous fibers that occur naturally: chrysotile, crocidolite, amosite, anthophyllite, tremolite, and actinolite. Among these, chrysotile and asbestos are the most common asbestos.

Although asbestos fibers are microscopic in nature, they are extremely durable and fire resistant and have most chemical reactions and breakdowns. These characteristics of asbestos were the reasons that supported its use for many years in a number of different commercial and industrial capacities. The power of asbestos, together with its heat resistance, has made it a choice material in a variety of products, including, but not limited to, roofing panels, floor tiles, roof materials, cement compounds, textile products, and automotive parts. Asbestos is now regulated strictly because exposure to this toxic metal can now be directly and scientifically linked to the number of lung and respiratory conditions including mesothelioma.

More about six different types of asbestos
Amosite asbestos
Commercial production of amosite, or "brown" asbestos, has ended over the last decade, and this type of asbestos is no longer mine. However, it was simultaneously the second most common form of asbestos, and as a result, many individuals exposed it during its peak in use. Amosite was used as insulation in factories and buildings, as well as both acoustic and anti-condensation materials. Its use has been banned in most countries over the past 30 years.

Chrysotile asbestos
The most common type of asbestos, the only species still mined, chrysotile was the most widely used in the developed countries of the world. Estimates show about 90-95% of all asbestos that remains in buildings in the United States and Canada of this diversity. Because it has been widely used, it represents most of the health problems, although companies that mine mines are still witness to their safety. Chrysotile is often used in fire-resistant and insulating products and is widely used on US warships during World War II and the Korean War.

Tremolite Asbestos
As a variety of amphibole asbestos fibers, tremolite asbestos is associated with the development of malignant mesothelioma and other cancers associated with asbestos. Like other types of asbestos, asbestos often consists of tremolite of magnesium and can range from white outside to dark green in color. Tremolite is particularly common in vermiculite deposits. Vermiculite contaminated with tremolite was responsible for the deaths of hundreds of miners in Libby, Montana, who worked at the Grace Vermiculite mine.

Crocidolite Asbestos
Asbestos crocidolite represents about 4% of asbestos once used in the United States. Crocidolite occurs in packages that are naturally formed long, sharp and straight. This "blue" asbestos is harder and brittle than other types of metal and can be easily broken, releasing dangerous fibers such as a needle that is easily inhaled. Crocidolite, without a doubt, is the most deadly form of asbestos. It is often used in the manufacture of yarns and lanyards, and as a material to promote plastic materials.

Asbestos anthophyllite
Asbestos anthophyllite, also known as "brown" asbestos, is mostly composed of iron and magnesium. Its fibers are known to be long and flexible. From the Amphibole sub-category, brown asbestos can be found in many talc mines and has been associated with some respiratory disorders. Is not conclusively associated with mesothelioma as other varieties of asbestos are. Because of their scarcity, anthophyllites were not often used in consumer products, but could be found in some cement and insulating products.


Aspinus actinolite
Asbestos acetinolite is a variety of amphibole asbestos subcategory, and as such, its makeup and consistency are similar to other forms of this subgroup. Mainly made of magnesium, acethenolite is very rare and ranges in color from white to dark brown. It was not known that actinolite is used in asbestos products because of scarcity, but it is known to be present in metamorphic rocks. As with all forms of asbestos, actinolite is a known carcinogen that can cause mesothelioma cancer.

Why Is Asbestos Hazardous?
The use of asbestos declined sharply in the late 1970s when it became clear that asbestos posed a threat to human health and safety. Today, asbestos is classified as a known human carcinogen. The durability property - which made asbestos very desirable for manufacturers - is what makes asbestos hazardous. Asbestos fibers are microscopic (approximately 0.02 diameter human hair) and, therefore, are easily inhaled. Once inhaled, the fibers adhere to the respiratory tract, including lining the lungs and internal cavity tissue. As asbestos fibers are usually completely rigid, they become in the soft inner tissues of the respiratory system and can not be easily expelled or broken down by the body.
