Centro de Documentacion de Fundación MAPFRE - The Mineralogy and size of airborne chrysotile and rock fragments : ramifications of using the NIOSH 7400 method

Notes: Sumario: The authors were interested in determining what minerals would be included in a phase contrast optical microscopy (PCM) fiber count, how the specific minerals differ in particle size and shape, and how the use of transmission electron microscopy (TEM) afects determination of fiber exposure. They also wanted to determine if tremolite was an important constituent of airborne dust in the mine because it is widely assumed that tremolite is ubiquitous in chrysotile deposits. Estimates of tremolite asbestos contamination in crysotile mines range as high as 1.5%Related records: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 53, nº 7, July 1992 ; p. 442-447Materia / lugar / evento: Higiene industrial Contaminantes químicos Mineralogía Crisotilo Contaminación atmosférica Amianto Control de la contaminación Métodos de análisis TEM Método N.I.O.S.H.
