“…Individual crystals sometimes show areas that display marked longitudinal etching, and produce flexible fibres apparently bordered by solution surfaces, as well as areas which produce more irregular fragments. The same process was also observed in alterations of clinopyroxene to amphibole (Germine, 1981).…”

“…chrysotile and the amphiboles. Rutile (TiO2) , which is chemically and crystallographically dissimilar to these minerals, occurs in leathery masses of flexible fibres at Franklin, New Jersey (Germine, 1985;Puffer et al, 1987). Flexible fibrous masses are composed of crystals which typically range from 0.07 to 0.10/xm.…”

Quantitative measurement of relative flexibility have been made on amphibole fibres based on calculation of bending strain of maximally bent fibre segments. Enhanced flexibility was found to be an inverse function of fibre diameter. Asbestos is therefore a morphological entity. These conclusions are supported by consistent observations of fibre diameter/flexibility relationships in amphiboles, serpentine, and rutile. Flexibility may arise from growth of thin crystals (primary flexibility), or from crystal diameter reduction (secondary flexibility). Mechanisms for secondary flexibility in amphiboles include splitting and solution along cleavage planes. Gross morphological characteristics are a poor indicator of microscopic habit, since coarsely fibrous minerals such as picrolite antigorite may not be fibrous after particle width reduction, and secondary asbestiform fibres are often derived from minerals with a non-fibrous morphology on gross examination.

“…While asbestos contamination may not be a universal problem in all water supplies, there have been a number of reports of asbestos in the groundwater and the surface waters of several locations (12,13). Although one report indicates that run-off water from asphalt shingles containing asbestos as a binder did not appear to contribute substantially to asbestos fibers found in cistern waters (13), a second report found concentrations as high as 500 million fibers/L in cisterns supplied with run-off water from asbestos cement shingle roofs (10).…”

This report is an assessment of all available literature that pertains to the potential risk of cancer associated with ingestion of asbestos. It was compiled by a working group to assist policy makers in the Department of Health and Human Services determine if adequate information was available for a definitive risk assessment on this potential problem and evaluate if the weight of evidence was sufficient to prioritize this issue for new policy recommendations. The work group considered the basis for concern over this problem, the body of toxicology experiments, the individual epidemiologic studies which have attempted to investigate this issue, and the articles that discuss components of risk assessment pertaining to the ingestion of asbestos. In the report, the work group concluded: 1) that no direct, definitive risk assessment can be conducted at this time; 2) that further epidemiologic investigations will be very costly and only possess sufficient statistical power to detect relatively large excesses in cancers related to asbestos ingestion; and 3) that probably the most pertinent toxicologic experiments relate to resolving the differences in how inhaled asbestos, which is eventually swallowed, is biologically processed by humans, compared to how ingested asbestos is processed. The work group believes that the cancer risk associated with asbestos ingestion should not be perceived as one of the most pressing potential public health hazards facing the nation. However, the work group does not believe that information was sufficient to assess the level of cancer risks associated with the ingestion and therefore, this potential hazard should not be discounted, and ingestion exposure to asbestos should be eliminated whenever possible.
