Abstract
The possibility that traditional vapor sampling measures provided reliable estimates of inhalation exposure during spray painting operations for automobiles was investigated. In spray booths where base coat paint and clear coat finish were applied to automobile bodies, measurements were made of aerosol vapor and droplets. Charcoal sorbent tubes (CSTs) diffusion monitors, and glass fiber filters followed by CSTs were used for measurement. Measured air concentrations of xylene (1330207) averaged about 2 parts per million (ppm) at base coat and less than 1ppm at clear coat application sites. For both processes toluene (108883) concentrations averaged about 0.1ppm. When toluene and xylene concentrations were determined using the diffusion monitors, the measurements exceeded those made by the other samplers. The apparent increase in sampling rate was attributed to membrane damage caused by the solvents. The authors note that the fraction of airborne solvent represented by the droplets will be influenced by both the solvent vapor pressure in the mixture and the original droplet size. Droplets in the solvents and processes tested here contained up to 50% of airborne solvent. The authors recommend that prefiltered CSTs be used for monitoring worker exposure to solvents in applications similar to spray painting.
