National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Physical and Chemical Characteristics of Airborne Fibers.

PB87234662

Publication Date	1979
Personal Author	Ayer, H. E.; Zumwalde, R. D.
Page Count	41
Abstract	The chemical and physical properties of fibers commonly found in the air were reviewed, and a definition of a fiber was developed. Fiber types discussed included organic fibers, mineral wool, fibrous glass, phytoliths, asbestos (1332214), chrysotile (12001295), crocidolite (12001284), amosite (12172735), anthophyllite (17068789), tremolite (14567738), actinolite (13768008), attapulgite (12174117), wollastonite (13983170), and other mineral fibers. Most of the organic fibers commonly found in indoor air were of animal and vegetable origin, while monofilamentous synthetic fibers were less frequently found. Airborne organic fibers may be of importance only in mills processing such materials. Amorphous fibers were found in the lungs of humans at autopsy and in air samples from urban areas. The authors recommend that controls be instituted to limit exposures to any airborne fibrous dust.
