HRCT/CT and associated spirometric effects of low Libby amphibole asbestos
In another study, activity-based air and surface sampling was conducted in three homes to evaluate amphibole asbestos
exposures during specific activities in attics containing VAI (Ewing et al.
As a substance of intense scientific and medical scrutiny, the use of amphibole asbestos
along with past practices and products that allowed fibres to be released into the air (like spray insulation) was blamed more so for asbestos-related illnesses.
In particular, even though the content of many materials that contain asbestos is predominantly chrysotile, such materials often contain small quantities of amphibole asbestos
impurities and even intentionally added amphiboles.
In addition to the vermiculite product, the exfoliation produced a waste material that contained up to 10% amphibole asbestos
[Minnesota Department of Health (MDH) 2005].
This fiber is not a form of asbestos but is comparable in size to amphibole asbestos
and is also biopersistent.
Internalization of Libby amphibole asbestos
and induction of oxidative stress in murine macrophages.

exposure, although there was considerable dispersion in the data.
OBJECTIVES: We sought to examine the importance of XRCC1 in protection against genotoxic effects of crocidolite and Libby amphibole asbestos
The processing, use, and transport of the ore, which was contaminated with amphibole asbestos
, led to generalized contamination of the community.
Libby amphibole asbestos
was determined to be composed of tremolite, winchite, and richterite (Meeker et al.
The Chrysotile Institute, a nonprofit organization funded by the Canadian government, maintains that chrysotile is not as toxic as amphibole asbestos
The vermiculite, mined extensively from the 1920s to 1990, was laced with toxic amphibole asbestos
, and the mining operations released asbestos into the air and contaminated the mine, processing sites, and many of the buildings and properties in town.
A vermiculite mine that operated in Libby from 1921 to 1990 exposed workers, their families, and the local environment to dangerous levels of toxic amphibole asbestos
But the construction that is transforming this once rural area has also dug up a health risk--thin needles of amphibole asbestos
, a particularly hazardous form of the mineral.
