Exposure to asbestos fibers has been known as health risk of the early 1900s. Several epidemiological studies involving exposure to asbestos with the development of lesions such as asbestos bodies in sputum, pleural plaques, diffuse thickening of the pleura, asbestosis, lung cancer and throat, gastrointestinal tumors, and diffuse mesothelioma of pleura and peritoneum.
In the documented presence of asbestos fibers in water and food concerns in relation to promoting the impact of possible long-term and still unknown exposure of the population of these fibers. Although many authorities consider brief or transient exposure to asbestos fibers as a dreamer and probably a risk factor, some epidemiologists claim that there is no risk threshold. Cases of mesothelioma have been found only in people whose exposure was breathing the air through ventilation systems. Other cases are very minimal (3 months or less) direct exposure.Commercial asbestos mining Wittenoom, Western Australia, occurred between 1945 and 1966. A group study of miners employed at the mine by announcing that the deaths occurred within the first 10 years after crocidolite exposure, 85 deaths related to mesothelioma had occurred by 1985. By 1994, reported 539 deaths due to mesothelioma were reported in Western Australia
