Chrysotile Asbestos | Asbestos Lung Mesothelioma and cancer ...

According to the U.S. Bureau of Mines,there are about 100 mineral fibers that "asbestos-like"fibers,but only six of them are recorded and regulated by the U.S. government. When asbestos which,most of the time these six fibrous minerals are mentioned.

The six asbestos minerals recognized by the government are:

?Tremolite asbestos

?Actinolite asbestos,

?Anthophyllite asbestos,

?Chrysotile Asbestos,

?Amosite asbestos

?Crocidolite asbestos.

These six types are broadly classified into two groups:1} Serpentine group consisting only of chrysolite asbestos,amphibole 2} group consisting of the remaining five asbestos.

The difference between these two main groups in their physical structure,the serpentine group is composed of minerals that form a layered and curly fibers while the amphibole group of minerals that straight fibers with a chain-like structure.

1-chrysotile

These are also known as white asbestos and are made of fine,silky,flexible white fibers. Chrysotile is composed of minerals crystallized in a serpentine pattern that means it consists of crystals that are formed in sheets. It is the most common type of asbestos,accounting for about 95 percent of all asbestos used commercially in the United States. Due to the widespread use of this fiber,chrysotile accounts for the majority of asbestos-related health problems in the world.

2-Tremolite

This type of asbestos most commonly found in metamorphic rocks. The color ranges from creamy white to dark green. Tremolite asbestos has been used for industrial purposes (although not as much as chrysotile) and is identified as an ingredient in some household products,mainly talc (which is also a known carcinogen). This form of asbestos is the main type of asbestos found in the infamous vermiculite mine in Libby,Montana.

3-Actinolite asbestos

This is a relatively common mineral also found in metamorphic rocks. The color of this type of asbestos is usually green,white or gray and it is closely related to the mineral tremolite (actinolite an increased presence of iron over magnesium sulfate than tremolite). Actinolite not have a strong history of commercial or industrial use,but it can be a contaminant in asbestos products. There are non-fibrous varieties of actinolite not pose the same threats to health associated with exposure to commercially exploited forms of asbestos.

4-Anthophyllite asbestos

This type of asbestos fiber is usually identified by its brittle white fibers are made of crystals and have a chain-like appearance. This type of asbestos is a common contamination of talc. Anthophyllite asbestos Although not often used for industrial purposes,the fibers occasionally be found in natural minerals that expand with the application of heat,such as vermiculite (commonly added to the garden soil).

5-Amosite asbestos

This type of asbestos is identified by are straight,brittle fibers that are light gray to brown color. Amosite is also known as brown asbestos. In recent years,amosite was often used as an insulating material and at a given time was the second most common type of asbestos. During the past decades,the commercial production of amosite has decreased and its use as an insulating material in Many countries banned.

6-Crocidolite asbestos

These are commonly known as blue asbestos,and it is identified by its straight blue fibers. This form is considered the most dangerous form of asbestos. Crocidolite asbestos occurs naturally in places like Australia,South Africa,Bolivia,the former Soviet Union and Canada.

Chrysotile Arizona 1914 to 1945 $6.74 Chrysotile Arizona was established at the bottom of Ash Creek Canyon as an asbestos mining town around 1914. Over time,the community?s existence has been nearly forgotten. Now,through notes,letters,original pictures,and first-hand accounts of one of Chrysotile?s oldest surviving residents,the town comes alive again on the pages of this book. Readers will learn about the good times and the ba?
