Abstrakt: Blood toluene was measured in a group of 100 workers occupationally exposed to a mean 8-h environmental toluene concentration of 128 μg/l (34 ppm), and in a group of 269 'normal' subjects without occupational exposure to toluene. The mean blood toluene of the workers at the end of the shift and the following morning, after 16 h, was 457 and 38 μg/l, respectively. The normal subjects had a blood toluene level of 1.1 μg/l. On the basis of the highly significant correlation between blood toluene and occupational exposure, it can be calculated that environmental toluene exposure of 188 and 377 μg/l (50 and 100 ppm) gives end-of-shift blood toluene levels of 690 and 1390 μg/l, respectively. The corresponding blood toluene levels on the following morning are 50 and 100 μ/l, respectively. [ABSTRACT FROM AUTHOR]
