Centro de Documentacion de Fundación MAPFRE - Aerosol evaluation difficulties due to particle deposition on filter holder inner walls

Notas: Sumario: The analysis of aerosol particles collected on aerosol samplers is most generally performed on the filter alone. A chemical digestion method, performed directly inside the filter cassette, avoids any external pollution or sample loss due to handling. A systematic comparison of these two methods, performed on different industrial sites, demonstrates that a sometimes significant fraction of the sampled aerosol deposits on the inner cassette walls, resulting in severe underestimation of the occupational hazard with the first method. A review of published laboratory studies clearly indicates that every particle entering the cassette is part of the sampleRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 4, August 1990 ; p. 399-403Materia / lugar / evento: Higiene industrial Contaminantes químicos Aerosoles Contaminación atmosférica Control de la contaminación Muestreador Filtros Muestreos Otros autores: Demange, M.
