Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond , and exceeds that of most metals. [ 12 ]
Beryllium poisoning is poisoning by the toxic effects of beryllium, or more usually its compounds. It takes two forms: Acute beryllium poisoning, usually as a result of exposure to soluble beryllium salts; Chronic beryllium disease (CBD) or berylliosis, usually as a result of long-term exposure to beryllium oxide usually caused by inhalation.
The overall prevalence of chronic beryllium disease among workers exposed to beryllium has ranged from 1–5% depending on industry and time period of study. [35] [36] [38] The general population is unlikely to develop acute or chronic beryllium disease because ambient air levels of beryllium are normally very low (<0.03 ng/m 3). [39]
