Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a naturally occurring, carcinogenic, fibrous silicate mineral.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 atmosphere by ...
Figure B shows lungs with asbestos-related diseases, including pleural plaque, lung cancer, asbestosis, plaque on the diaphragm, and mesothelioma. All types of asbestos fibers are known to cause serious health hazards in humans. [1][2][3] The most common diseases associated with chronic exposure to asbestos are asbestosis and mesothelioma.
Asbestosis is long-term inflammation and scarring of the lungs due to asbestos fibers. [4] Symptoms may include shortness of breath, cough, wheezing, and chest tightness. [1] Complications may include lung cancer, mesothelioma, and pulmonary heart disease. [1][9] Asbestosis is caused by breathing in asbestos fibers.
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. People who worked in jobs with high asbestos dust exposure are at the highest risk ...
Asbestiform. Asbestiform is a crystal habit. It describes a mineral that grows in a fibrous aggregate of high tensile strength, flexible, long, and thin crystals that readily separate. [1] The most common asbestiform mineral is chrysotile, commonly called "white asbestos ", a magnesium phyllosilicate part of the serpentine group.
Riebeckite. Riebeckite is a sodium -rich member of the amphibole group of silicate minerals, chemical formula Na 2 (Fe 2+3 Fe 3+2)Si 8 O 22 (OH) 2. It forms a solid solution series with magnesioriebeckite. It crystallizes in the monoclinic system, usually as long prismatic crystals showing a diamond-shaped cross section, but also in fibrous ...
Serpentine from Poland. Serpentine subgroup (part of the kaolinite -serpentine group in the category of phyllosilicates) [1] are greenish, brownish, or spotted minerals commonly found in serpentinite. They are used as a source of magnesium and asbestos, and as decorative stone. [5]
Asbestos abatement. Weathered fibrous asbestos sheeting showing loose fibres. In construction, asbestos abatement is a set of procedures designed to control the release of asbestos fibers from asbestos-containing materials. [1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when ...
