Clinically advanced cases of asbestosis may lead to respiratory failure. When a stethoscope is used to listen to the lungs of a person with asbestosis, they may hear inspiratory "crackles". The characteristic pulmonary function finding in asbestosis is a restrictive ventilatory defect. [ 13 ]
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.
In 1935, officials of Johns-Manville and Raybestos-Manhattan instructed the editor of Asbestos magazine to publish nothing about asbestosis. [42] In 1936, a group of asbestos companies agreed to sponsor research on the health effects of asbestos dust, but required that the companies maintain complete control over the disclosure of the results.

Asbestos, which was once common in home insulation and other products, is banned in more than 50 countries, and its use in the U.S. has been declining for decades. The only form of asbestos known ...
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 ...
However, the most famous (infamous) example is pulmonary toxicity due to asbestos. [7] Asbestos can lead to a highly dangerous (i.e., highly malignant) lung cancer called malignant pleural mesothelioma, sometimes also simply called mesothelioma. As a consequence, the use of asbestos is now completely prohibited by law in most countries.
Labrador lung (found in miners in Labrador, Canada) – mixed dust containing iron, silica and anthophyllite, a type of asbestos; Stannosis – tin oxide; Talcosis – talc; Baritosis - a benign type of pneumoconiosis caused by barium inhalation; it typically causes little or no overgrowth, hardening, and/or fibrosis. [12] Mixed-dust ...
They are indicators of asbestos exposure, and the most common asbestos-induced lesion. [3] They usually appear after 20 years or more of exposure and never degenerate into mesothelioma. They appear as fibrous plaques on the parietal pleura, usually on both sides, and at the posterior and inferior part of the chest wall as well as the diaphragm. [4]
