Title = Toluene 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 m 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.
