Monitoring of industrial exposure to dimethylformamide by analysis of alveolar air.
The occupational exposure to Dimethylformamide was studied by testing the environmental and alveolar air of 8 workers, at hourly intervals, during the workshift. The correlations between alveolar and environmental concentrations of Dimethylformamide turned out to be statistically significant at all the intervals studied, except at the 4th hour when the correlation was not significant. In six out of the eight workers studied, the correlation between alveolar and environmental concentrations was statistically significant. Only in two workers was the correlation not significant. On the basis of the slope of the regression line between all the data, the alveolar concentration of Dimethylformamide turned out to correspond to 27,8% of the environmental concentration.
