What are the types of asbestos fibers?
Asbestos Lung Cancer.
There are two major groups of asbestos fibers,:
  • - amphiboles
  • - chrysotile fibers.

Chrysotile (white asbestos), also called "Serpentine" fibers, are long and curled. The amphiboles, long straight fibers (including actinolite, amosite, anthrophyllite, crocidolite, and tremolite) are much more likely to cause cancer of the lining of the lung (mesothelioma) and scarring of the lining of the lung (pleural fibrosis). Either group of fibers can cause disease of the lung, such as asbestosis.

The risk of developing asbestos-related lung cancer varies between fiber types. Studies of groups of patients exposed chrysotile fibers show only a moderate increase in risk. On the other hand, exposure to amphibole fibers or to both types of fibers increases the risk of asbestos lung cancer by two fold. Although the Occupational Safety and Health Administration (OSHA) has a standard for workplace exposure to asbestos (0.2 fibers/milliliter of air), there is debate over what constitutes a safe level of exposure. While some believe asbestos-related disease is a "threshold phenomenon," which requires a certain level of exposure for disease to occur, others believe there is no safe level of asbestos.

In most buildings, asbestos does not become airborne. However, surfaces that are damaged or disturbed can cause asbestos to become inhalable. High concentrations can occur after cutting, sanding, or remodeling asbestos- containing materials.

Reducing asbestos exposure involves either the removal or sealing of asbestos-containing materials. Inexperienced attempts to remove asbestos can release dangerous levels of the fibers.
