EXPOSURE & HEALTH EFFECTS
Routes of exposure Exposure mainly occurs via inhalation. Effects of short-term exposure	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged inhalation may cause asbestosis (fibrosis of the lungs), pleural plaques, thickening and effusions. This substance is carcinogenic to humans. This substance causes cancer of the lung, mesothelioma, cancer of the larynx, and cancer of the ovary in humans. There is limited evidence that this substance causes colorectal cancer or cancer of the pharynx or stomach.
