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.

In Vitro Mordenite Fiber Dissolution at Acidic pH.

PB2006103436

Publication Date	2005
Personal Author	Stephenson, D.; Hoover, M. D.
Page Count	28
Abstract	Mordenite is an aluminosilicate zeolite mineral similar to asbestos. The unique structural and chemical properties make mordenite favorable to a wide variety of commercial applications ranging from waste-effluent treatment to paper production. Interest in mordenite, as an occupational inhalation hazard, arose when it was discovered that the fibrous form of the mineral exists in the subsurface of Yucca Mountain, NY, the site of a federally proposed nuclear waste repository. During preliminary geologic investigations at Yucca Mountain, workers performing dry-drilling operations were potentially being exposed to aerosols of mordenite. In addition, environmental exposures to zeolites (including mordenite) were brought to the world's attention when a reported outbreak of mesothelioma was documented in the Cappadocia region of Turkey.
