Introduction

Background

Pneumoconiosis is the general term for lung disease caused by inhalation and deposition of mineral dust.

Pneumoconiosis caused by asbestos inhalation is called asbestosis. The word asbestos is derived from Greek and means inextinguishable, and asbestos is a group of naturally occurring, heat-resistant fibrous silicates. Asbestos fibers are long and thin (length-to-diameter ratio >3) and may be either curved or straight. The curved fibers are called serpentine (chrysotile is the prime example), and the straight fibers are amphiboles. Several different types of amphiboles (ie, amosite, anthophyllite, tremolite, actinolite, crocidolite) have been recognized. Chrysotile is by far the most common type of asbestos fiber produced in the world and accounts for virtually all asbestos used commercially in the United States.

Production and use of asbestos increased greatly between 1877 and 1967. In the 1930s and 1940s, scientists recognized a causal link between asbestos exposure and asbestosis. In the 1950s and 1960s, researchers established asbestos as a predisposing factor for bronchogenic carcinoma and malignant mesothelioma.
