Centro de Documentación de Fundación MAPFRE - Variability of particle size-specific fractions of personal coal mine dust exposures

Notas: Sumario: This study estimated the ratio of the tracheo-bronchial dust fraction to the fraction collected by a respirable dust sampler for a variety of job classifications found in conventional, continous, and logwall coal mining sections. The ratios could then be applied in epidemiologic studies to existing respirable dust measurements to estimate thoracic mass concentrations for evaluation of the relative importance of the respirable and thoracic dust fractions to obstructive lung disease. Data collected include particle size distributions from four U.S. underground coal mines using eight-stage personal cascade impactorsRegistros relacionados: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 56, nº 3, March 1995 ; p. 243-250Materia / lugar / evento: Higiene industrial Minería Carbón Polvo Enfermedades pulmonares Vías respiratorias Evaluación higiénica Otros autores: Seixas, Noah S.
