Health effects of synthetic vitreous fibers

Abstract

This article reviews the terminology and manufacturing process for synthetic vitreous fibers. The in vitro and in vivo animal experimental data that correlate fiber toxicity with dose, dimensions, and durability are summarized. Occupational exposure data are presented as well as the potential irritant effects of synthetic vitreous fibers. The ongoing human morbidity and mortality studies are summarized along with current occupational exposure standards. The discussion correlates physical properties related to fiber toxicity and the types of synthetic vitreous fibers.
