Centro de Documentacion de Fundación MAPFRE - Follow-up study on the lung retention of welding fumes among shipyard welders

Notas: Sumario: Lung retention and clearance of welding fumes were followed during the years 1976-1982 among 48 shipyard arc welders. The subjects were divided into four groups according to their average exposure time, which varied from 3 to 49 yr. The amount of lung-retained dust was estimated using magnetopneumography. The results indicate that the average clearance rate was 20% per yr. The individual clearances varied between 10 and 30% per yr. Improvements in hygiene in the shipyard were clearly seen in the changes of lung retention ratesRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 4, 1983 ; p. 449-452Materia / lugar / evento: Higiene industrial Contaminantes químicos Humos tóxicos Soldadura por arco Enfermedades profesionales Enfermedades pulmonares Astilleros Otros autores: Kalliomäki, Pirkko-Liisa
