520  ‎$a‎Lung 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 rates
