Editing Beryllium (section)

===Detection===
Early researchers undertook the highly hazardous practice of identifying beryllium and its various compounds from its sweet taste. A modern test for beryllium in air and on surfaces has been developed and published as an international voluntary consensus standard, ASTM D7202. The procedure uses dilute [[ammonium bifluoride]] for dissolution and fluorescence detection with beryllium bound to sulfonated hydroxybenzoquinoline, allowing up to 100 times more sensitive detection than the recommended limit for beryllium concentration in the workplace. Fluorescence increases with increasing beryllium concentration. The new procedure has been successfully tested on a variety of surfaces and is effective for the dissolution and detection of refractory beryllium oxide and siliceous beryllium in minute concentrations (ASTM D7458).<ref>{{Cite web|url=http://www.astm.org/Standards/D7458.htm|title=ASTM D7458&nbsp;–08|access-date=8 August 2009|publisher=American Society for Testing and Materials|archive-date=12 July 2010|archive-url=https://web.archive.org/web/20100712085740/http://www.astm.org/Standards/D7458.htm|url-status=live}}</ref><ref>{{Cite journal|doi=10.1520/JAI13168|title=Development of a New Fluorescence Method for the Detection of Beryllium on Surfaces|date=2005|last1=Minogue|first1 =E.
