| asbestos, amphibole | <chemical> A class of asbestos that includes silicates of magnesium, iron, calcium, and sodium. The fibres are generally brittle and cannot be spun, but are more resistant to chemicals and heat than asbestos, serpentine. Pharmacological action: carcinogens. (12 Dec 1998) |

| amphibole | <chemical> A common mineral embracing many varieties varying in colour and in composition. It occurs in monoclinic crystals; also massive, generally with fibrous or columnar structure. The colour varies from white to gray, green, brown, and black. It is a silicate of magnesium and calcium, with usually aluminium and iron. Some common varieties are tremolite, actinolite, asbestus, edenite, hornblende (the last name being also used as a general term for the whole species). Amphibole is a constituent of many crystalline rocks, as syenite, diorite, most varieties of trachyte, etc. See Hornblende. Origin: Gr. Doubtful, equivocal, fr. To throw round, to doubt: cf. F. Amphibole. Hauy so named the genus from the great variety of colour and composition assumed by the mineral. Source: Websters Dictionary (01 Mar 1998) |
| asbestos | <chemical> A fibrous incombustible mineral known to cause fibrosis and scarring in the lungs. Also a known carcinogenic material (can cause lung cancer, mesothelioma). (27 Sep 1997) |
| asbestos, amosite | <chemical> Asbestos, grunerite. A monoclinic amphibole form of asbestos having long fibres and a high iron content. It is used in insulation. Pharmacological action: carcinogens. Chemical name: Asbestos, grunerite (12 Dec 1998) |
| asbestos bodies | Ferruginous body's with asbestos fibres as a core; a histologic hallmark of exposure to asbestos. (05 Mar 2000) |
| asbestos corn | A granulomatous or hyperkeratotic lesion of the skin at the site of deposit of asbestos particles. Synonym: asbestos wart. (05 Mar 2000) |
| asbestos, crocidolite | <chemical> Crocidolite. A lavender, acid-resistant asbestos. Pharmacological action: carcinogens. Chemical name: Crocidolite (12 Dec 1998) |
| asbestos liner | A layer of asbestos used to line a dental casting ring so that during the heating and expansion of the investment the compression of the liner will free the investment from the restraint of the ring. (05 Mar 2000) |
| asbestos lung disease | <radiology> Pleural plaques, earliest finding, may be only evidence, parietal pleura, 15-20 yrs after exposure, calcified after ca. 30 yrs, asbestosis, interstitial lung disease, perihilar regions to lung bases, shaggy heart, no cavitation or progressive massive fibrosis as in silicosis, crocidolite (blue) form most carcinogenic, associated with: malignant pleural mesothelioma, peritoneal mesothelioma, GI-tract malignancy (12 Dec 1998) |
| asbestos, serpentine | <chemical> A type of asbestos that occurs in nature as the dihydrate of magnesium silicate. It exists in two forms: antigorite, a plated variety, and chrysotile, a fibrous variety. The latter makes up 95% of all asbestos products. Pharmacological action: carcinogens. (12 Dec 1998) |
| asbestos wart | A granulomatous or hyperkeratotic lesion of the skin at the site of deposit of asbestos particles. Synonym: asbestos wart. (05 Mar 2000) |
| amphibole asbestos |
Amphibole defines an important group of dark-colored rock-forming inosilicate minerals composed of double chain SiO4 tetrahedra linked at the vertices and generally containing ions of iron and/ or magnesium in their structures. In chemical composition and general characteristics they are very similar to the pyroxenes and, like them, fall into three series according to their system of crystallization. ...
