Body burden profiles of single and mixed solvent exposures
The dynamics of inhaled solvents have not been studied extensively for exposure conditions involving combinations of chemical agents. An ongoing laboratory study examining psychomotor performance effects on human volunteers exposed to spray paint agents offered an opportunity to gather data on the body burden profiles produced by the inhalation of two solvents alone and in combination. Breath and blood samples were collected from 70 male and female subjects who were randomly assigned to four treatment conditions: chemical placebo, 250 ppm acetone, 200 ppm methyl ethyl ketone, or 125 ppm acetone/100 ppm methyl ethyl ketone. The exposures lasted for four hours. No interaction between the two solvents affecting uptake or elimination was noted. There were no significant differences between the uptake and elimination in males and females. The results are discussed in relation to physiological simulation modeling of the exposure.
