Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
The amount and length of an individual's exposure to asbestos are the primary factors that determine the level of risk. The longer one is exposed to the substance, the higher their risk of developing lung damage. Families of exposed workers can be affected because asbestos fibers from clothing and hair can end up in the home.
This fracture process can keep occurring and one larger asbestos fiber can ultimately become the source of hundreds of much thinner and smaller fibers. When fibers or asbestos structures from asbestos containing materials (ACM) become airborne, the process is called primary release.
WASHINGTON (AP) — Cosmetic companies would have to take extra steps to ensure that any products containing talc are free of asbestos under a federal rule proposed Thursday. The proposal from the Food and Drug Administration and mandated by Congress is intended to reassure consumers about the safety of makeup, baby powder and other personal ...
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
A ferruginous body is a histopathologic finding in interstitial lung disease suggestive of significant asbestos exposure . Asbestos exposure is associated with occupations such as shipbuilding, roofing, plumbing, and construction. They appear as small brown nodules in the septum of the alveolus.
Asbestos is a naturally occurring group of silicate minerals that can readily be separated into thin strong fibres that are flexible, heat resistant and chemically inert. [6] Within the United Kingdom and elsewhere in the world, asbestos was used extensively as a building material from the 1950s to the 1980s. [7]
