in Rotogravure Printed Brochures: High Speed Emission Testing and Comparison
with Exposure Data
|Abstract = Residual
solvent in rotogravure printed brochures has given rise to complaints and
injury reports among postal workers in Denmark. A method has been developed
for a fast determination of the emission of toluene from rotogravure printed
brochures by use of the field and laboratory emission cell (FLEC). Emitted
compounds were identified by gas chromatography-mass spectrometry. Toluene
head space concentration in packs of brochures was measured by use of a
photoionization detector. The emission decay was monitored by use of the
FLEC with photoionization detection or with sampling on Tenax TA. Highly
time-resolved personal exposure measurements were performed during simulated
mail handling in a 41 m³ test chamber using a newly developed photoacoustic
detector, paralleled by personal sampling on Tenax TA. Toluene constituted
about 99 percent of the emission. Head space concentrations up to 2145
ppm were measured. The FLEC-photoionization detector measurements showed
toluene emission decay curves rapidly decreasing during the first 1 to
3 minutes. Areas under the curves correlated with FLEC-Tenax measurements.
The FLEC-photoionization detector method was repeatable and seemed to be
reproducible. Highly time-resolved personal exposure measurements during
simulated mail handling showed Frequently repeated peak exposures exceeding
the Danish occupational exposure limit. There was a fair correlation between
personal exposure measurements, toluene head space measurements, and FLEC
measurements. The FLEC-photoionization detector method yields a rapid determination
of toluene emission and is recommended for on-line production quality control.
