- Physical Description: Asbestos is a slender, fine, flaxy fiber. Long term occupational exposure to the dust can result in lung cancer. Asbestos is resistant to fire and most solvents. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used as a heat resistant material, in cement, furnace bricks, and brake linings. Source: CAMEO Chemicals

- Health Effects: Infected people develop a slow buildup of scar-like tissue in the lungs and in the membrane that surrounds the lungs, so breathing becomes difficult. Blood flow to the lung may also be decreased, and this causes the heart to enlarge. This disease is called asbestosis. Infected people have increased chances of getting two principal types of cancer: cancer of the lung tissue itself and mesothelioma, a cancer of the thin membrane that surrounds the lung and other internal organs. The cellular immune system of the patient can be depressed. Also, deletions of chromosome segments have been noted in human mesothelioma cells or cell lines. (L222) Source: Toxin and Toxin Target Database (T3DB)
- Toxicity Summary: When asbestos fibers are inhaled, many are deposited on the epithelial surface of the respiratory tree. Fibers that are retained in the lung or mesothelium for long periods of time are capable of producing chronic inflammation and fibrotic and tumorigenic effects. These effects may be mediated by direct interactions between the fiber and key cellular macromolecules, or they may be mediated by the production of reactive oxygen species and other cellular factors originating from alveolar macrophages. In addition, the physical-chemical nature of the fiber appears to be an important determinant of toxicity. It is generally agreed that exposure to amphibole fibers can produce mesothelioma, and that the potency of amphibole fibers to produce mesothelioma is greater than that of chrysotile. Asbestos fibers can adsorb to a variety of cellular macromolecules (e.g., proteins,membrane lipids, RNA, DNA). The coulombic forces between the asbestos fiber and some of these macromolecules may induce conformational changes, and these changes could affect protein function and chromosomal fidelity. Fibers found to be translocated near the nucleus can interact with the cytoskeleton and interfere with c Source: Toxin and Toxin Target Database (T3DB)
- Uses: Asbestos are used in building materials (roofing shingles, ceiling and floor tiles, paper products, and asbestos cement products), friction products (automobile clutch, brake, and transmission parts), heat-resistant fabrics, packaging, gaskets, and coatings. Some vermiculite or talc products may contain asbestos. Exposure most likely by breathing air containing asbestos fibers or by drinking asbestos fibers that are present in water.
