Notas: Sumario: The purpose of the present study was to create a synthetic work situation under semilaboratory conditions by combining one grinding period and two MMA (manual metal arc) welding periods and subsequently comparing these results with measurements and fume concentrations during welding shop. Also, a comparison between background and breathing zone fume concentration during regular welding was investigated. Finally, it was of interest to observe the duty cycles of pure welding and of pure grindingRegistros relacionados: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 53, nº 5, May 1992 ; p. 290-297Materia / lugar / evento: Higiene industrial Contaminantes químicos Humos tóxicos Polvo Partículas ambientales Soldadura Muestreos Otros autores: Karlsen, Jan T.
