Anthophyllite Asbestos
Similar to other asbestos types, anthophyllite asbestos is a mineral known to causemesothelioma cancer. However, most studies indicate the risk of developing mesothelioma from anthophyllite exposure is much less than it is from exposure to other types of asbestos.
Although it took much longer for anthophyllite to be recognized as a mesothelioma risk than it did for amosite, chrysotile and crocidolite asbestos, there is a clear connection from exposure to it and to the development of mesothelioma.
In one 1989 study, 19 cases of mesothelioma were analyzed in Finland. Of the 19 cases, six were found to be predominantly affected by anthophyllite asbestos fibers.
Another study from 1994 reported four cases of mesothelioma among 999 miners of anthophyllite. The latency period for mesothelioma development ranged from 39 to 58 years, and the length of exposures varied from 13 years to 31 years. The miners who were diagnosed also had asbestosis and were smokers or former smokers.
Uses of Anthophyllite
Anthophyllite is one of the rarest types of asbestos and does not have a long history of commercial use. The mining of this mineral began in Finland in 1890. Since then, smaller deposits were mined in the southern states of North Carolina and Georgia.
While considered to be among the noncommercial types of asbestos, anthophyllite has been used in products containing minerals such as vermiculite and talc.
Talc plays a part in anthophyllite development. When anthophyllite forms because of the presence of sustained high temperatures, talc destabilizes and falls apart. Traces of anthophyllite may be present in talc and related products such as talcum powder.
