What is asbestos? Question 7

Asbestos is a naturally occurring group of minerals that have been mined and used in different industries since the late 1800s. 

It is an extremely poor conductor of heat and does not conduct electricity, and therefore it has been widely used as an insulator. The flexible asbestos fibers are woven after being separated into thin threads. 

The fibers tend to break easily, and the dust that is formed from them breaking can float in the air and stick to clothes. The fibers can also be inhaled or swallowed and can result in serious health problems, including asbestosis, lung cancer, and mesothelioma.

There are six types of asbestos: amosite, crocidolitenthophyllite, actinolite, tremolite, and chrysotile. The first five types are called amphibole asbestos, and they all have needlelike fibers. 

Chrysotile has a different texture, composition, and behavior than amphibole asbestos. Although some findings suggest that amphibole asbestos is more cancer causing than chrysotile, the topic remains controversial.  

Recently, other types of mined minerals have been found to be associated with asbestos, including vermiculite and taconite. Vermiculite has been used in insulation, and recently there has been great concern that it can be associated with mesothelioma. 

Vermiculite is also mixed into soil to lighten it and make it more porous, for gardening. Vermiculite mining was performed in Libby, Montana, and the number of mesothelioma cases reported in that community has increased significantly. Moreover, many homes across the nation have used vermiculite for insulation.
