Centro de Documentacion de Fundación MAPFRE - Size distributions of chrysotile asbestos in a friction products factory as determined by transmission electron microscopy

Notas: Sumario: Airborne chrysotile asbestos size distributions have been measured by transmission electron microscopy from air samples taken in a factory making clutches and brake shoes. The median diameters on samples taken at the three processes were 0.08, 0.13 and 0.13 microm, and the median lengths were 0.86,1.4 and 1.5 microm. Median aspect ratios were close to 10. A few per cent of fibres were longer than 5 microm, and between a fifth and a half of these would be counted by a phase-contrast optical microscope resolving 0.3 micromRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 4, 1989 ; p. 583-590Materia / lugar / evento: Higiene industrial Contaminantes químicos Amianto TEM Microscopios Crisotilo Métodos de análisis Fibra mineral Casos prácticos Otros autores: Scott, R.M.
