EXPOSURE TO ASBESTOS AND
During the past two decades, ill health resulting from exposure to asbestos has been the subject of intensive observation and research' — probably more intensive than research on any other environmental agent.2 In the most direct target organ, the lung, and in its pleural coverings, there is a wide spectrum of response after exposure; not only acute and chronic inflammatory diseases but also cancer of these organs may occur. Research has been stimulated by the belief that the more complete our understanding of the mechanisms of pathogenesis, the better will be our ability to control the continued use of this mineral in today's Complex technological world. 3
