Chrysotile Asbestos and Mesothelioma
نویسنده
چکیده
Assuming an average latency of 42 years, the authors predict that incidence rates will peak in 2009 and that diagnoses will peak in 2014. However, they caution that ongoing use of chrysotile asbestos (which has been implicated but not conclusively established as a cause of mesothelioma) and the release of asbestos fibers from older buildings during demolition or reno vation may slow the projected decline.

Mesothelioma from chrysotile asbestos: update.
PURPOSE There are different mineral classes of asbestos, including serpentines and amphiboles. Chrysotile is the main type of serpentine and by far the most frequently used type of asbestos (about 95% of world production and use). There has been continuing controversy over the capability of chrysotile asbestos to cause pleural and peritoneal mesothelioma. This review is to help clarify the issu...
متن کاملAsbestos fibers contributing to the induction of human malignant mesothelioma.
UNLABELLED To elucidate the features of the asbestos fibers contributing to the induction of human malignant mesothelioma, we used high-resolution analytical electron microscopy to determine the type, number, and dimensions of asbestos fibers in lung and mesothelial tissues in 168 cases of mesothelioma. RESULTS 1. Asbestos fibers were present in almost all of the lung and mesothelial tissues ...
متن کاملThe risk of mesothelioma from exposure to chrysotile asbestos.
PURPOSE OF REVIEW This review assesses the risk of developing diffuse malignant mesothelioma of the pleura from exposures to chrysotile fibers and contrasts it with the known risk of amphibole asbestos. RECENT FINDINGS Although a rare cancer, the mortality rates of pleural mesothelioma continue to be significantly elevated because of past occupational exposures to airborne asbestos fibers. Ne...
متن کاملMesothelioma and asbestos.
The current state of knowledge concerning mesothelioma risk estimates is reviewed. Estimates of the risk of mesothelioma exist for the commercial asbestos fiber types chrysotile, amosite and crocidolite. Data also exist on which to assess risks for winchite (sodic tremolite) and anthophyllite asbestos. Uncertainty in estimates is primarily related to limitations in measurements of exposure. Dif...
متن کاملMalignant mesothelioma among employees of a Connecticut factory that manufactured friction materials using chrysotile asbestos.
There is ongoing argument about the potency of chrysotile asbestos to cause malignant mesothelioma. Risk assessment for chrysotile is influenced by the alleged absence of mesotheliomas among workers at the Raybestos Manhattan friction products plant in Connecticut, a plant that essentially used only chrysotile asbestos. Regrettably, the statement that there is an absence of mesothelioma deaths ...
متن کاملChrysotile as a cause of mesothelioma: an assessment based on epidemiology.
There has been a longstanding debate about the potential contribution of chrysotile asbestos fibers to mesothelioma risk. The failure to resolve this debate has hampered decisive risk communication in the aftermath of the collapse of the World Trade Center towers and has influenced judgments about bans on asbestos use. A firm understanding of any health risks associated with natural chrysotile ...
