| Abstract |
This study investigated whether traditional vapour sampling measures provide reliable estimates of inhalation exposure during spray painting of automobiles. Xylene and toluene were tested as representative solvents. Measured air concentrations of xylene averaged about 2ppm at base-coat paint applications and less than 1ppm at clear coat applications. Toluene concentrations averaged about 0.1ppm for both processes. Comparisons of different samplers showed that droplets produced during the spraying of both base coat and clear coat operations retain liquid solvent when the droplets reach the breathing zone of workers. The fraction of airborne solvent represented by the droplets is influenced by both the solvent vapour pressure in the mixture and the original droplet size. For the solvents and processes tested here droplets contained up to 50% of airborne solvent. The use of prefiltered charcoal sorbent tubes is recommended for monitoring worker exposure to solvents in spray application processes. |
