Abstract
In an earlier cross-sectional study 47 formaldehyde glueing workers and 20 non-exposed control subjects were examined. In a follow-up study, five years later, 13 subjects had been transferred to other jobs whereas 21 were still occupationally exposed to formaldehyde. The results indicate a slow progress of lung function impairment in excess of the one due to normal ageing, at an average exposure to formaldehyde of 0.4 - 0.5 mg/m3 of air. The progress was significant for the FEV75-25 variables. These values returned to normal among non-smokers during a four-week vacation but remained unchanged among the smokers. A dose-effect relationship was found between exposure to formaldehyde and decrease in lung function among smokers.
