A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).
included in analyses (age, level of education, carbohydrate-deficient
transferrin as an alcohol marker, and trait anxiety as personality
characteristic) had no major exposure impacts. LWAE or current exposure
measures were not significantly affected byrepeated-measures analyses of
main cause of variability were age and education although,
carbohydrate-deficient transferrin and trait anxiety had some impacts on
the test results.
Employees (total of 192) from 14 magazine
rotary printing plants were classified into groups of "high" (printing
area) vs "low" (end-processing) and "short" vs "long" exposure.
Attention (symbol digit substitution, switching attention, simple
reaction), memory (digit span forward and backwards, immediate and
delayed reproduction of pictures), and psychomotor functions
(steadiness, line tracing, aiming, tapping, peg board) were measured as
There was no evidence that long-term
exposure to toluene at 26 ppm for 21 years had any effects on cognitive
function. Evidence for psychological performance effects due to
long-term toluene exposure below 50 ppm could not be proved. The human
NOAEC from this study was 26 ppm (98 mg/m3).
