A memorandum from the Director General of the Asbestos International Association forwarding, for information, notes on a 22 November 1984 meeting with Asbestosis Research Council doctors and a paper by Dr. A. A. Hodgson on tremolite in chrysotile. The meeting notes describe research on tremolite as a contaminant of chrysotile and its possible role in asbestos-related disease, and the efforts to develop a commercial test for tremolite content. The Hodgson paper (dated 30.10.1984) discusses the occurrence of tremolite in chrysotile and possible chemical, density, flotation and UV methods for identifying and separating it.
