| Research Abstract |
To investigate the relationship among stationary monitoring and personal monitoring in workplaces using solvent mixture (survey 1) and single toluene (survey 2), three sets of air samples were taken. A first set of samples (WP) was taken at many points equally distributed in the workplace to get an average value by A sampling. A second set (PW) was obtained from places proximity of the workers, a third set (BZ) was secured from the breathing zone of the workers. In both surveys, close correlation were found among the concentrations for each air sampling, i.e. there was a close relationship when comparing (PW) to (BZ) and (WP) to (BZ). In survey 2, there was also a close relationship of the concentration of toluene in the air of (BZ) or (WP) with the concentration of toluene and hippuric acid in the urine of the workers. The results suggest that the concentration of solvents in the places proximity of workers is a useful indicator of the amount of exposure to workers who remained same place most of their working time.
