Investigation of pulmonary function among employees exposed to low levels of monomeric isocyanates and solvents at an automobile finishings plant.
There have been reports in the literature of decrements in pulmonary function associated with long-term, low-level monomeric isocyanate exposure combined with solvent exposure. This cross-sectional study examines the relationship between these exposures and pulmonary function in an automobile paint and coating (finishes) plant. A job exposure matrix was developed for isocyanate and solvent exposure; years in a work task were used as a surrogate for exposure. Recent pulmonary function tests were used as the outcome variables; specifically the difference between predicted and actual FEV1 and FVC. The results of the analysis demonstrated no statistically significant relationship between combined isocyanate and solvent exposure and decline in pulmonary function. There was a statistically significant negative correlation between solvent exposure and FEV1 and FVC.
