Section: ArticlesTitle: Occupational exposure and analysis of microcrystalline cristobalite in mullite operations / Marija Janko... [et al.]Notes: Sumario: Three analytical methods currently used for crystalline free silica determination in occupational exposure samples were evaluated for their applicability to ceramic materials containing synthetic mullite. X-ray powder diffraction is the only method that can be used with sufficient precision and potentially adequate accuracy for occupational exposure monitoringRelated records: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 50, nº 9, September 1989 ; p. 460-465Materia / lugar / evento: Higiene industrialContaminantes químicosPolvo de síliceCerámicaRiesgo laboralControl de contaminantesMuestreosMétodos analíticosOtros autores: Janko, Marija Secondary titles: Título: American Industrial Hygiene Association journal Other categories: 872Rights: In Copyright (InC)
