Title Potential significance of airborne fiber dimensions measured in the U.S. refractory ceramic fiber manufacturing industry
Bibliographic information Aug. 1999, Vol.36, No.2, p.286-298. Illus. 69 ref.
Abstract To determine dimensions of airborne fibres in the U.S. refractory ceramic fibre (RCF) manufacturing industry, fibres collected through personal air sampling for employees at RCF manufacturing and processing operations were measured. Data were derived from transmission electron microscopy analyses of 118 air samples collected over a 20-year period. Characteristics of sized fibres include: diameter measurements of < 0.19 to 1.0Ám, of which 75% are less than 0.6Ám; and length ranging from < 0.6 to > 20Ám, with 68% of fibres between 2.4 and 20Ám. Exposures in RCF manufacturing include airborne fibres with dimensions (diameter < 0.1-0.4Ám, length < 10Ám) historically associated with biological effects in pleural tissues. Air sampling data and a review of studies relating fibre size to pleural effects in animals and humans support the belief that information on fibre dimensions is essential for studies with synthetic vitreous fibres.
