碩士 === 弘光科技大學 === 職業安全與防災研究所 === 99 === Abstract This research to the board, the PP delivers and transfer paper in three different labor environment of printed material, raw material samples for sample analysis of air samples, the raw material sample of the material labor homework environment to carry on the sample analysis, with activate carbon take care of(100/50 mgs) for sample lie the quality, the carbon disulfide conduct and actions takes off to attach, the instrument carries on the analysis with the Spelco WAX tube column(1.0 μ ms of the 30 m × 0.53 mm ×) for the Aglient 6890 GC-FID. The sample, the printing ink sample and the melting agent sample layer diagram carries on the ratio on the air to, To study a variety of printed material the use of volatile solvents and inks to the hazards of substances in the air, according to labour actually harm species exposed class. Study the result detection to aim at the former research in measures of the bane thing is in the version and the PP delivering steeping plank, analyze to find to did not have the Methyl ethyl ketone , is differently printed the material in the melting agent used because the printing ink vaporizes the speed the dissimilarity, the ketone melting agent increased also would be different, among them, the Cyclohexanone of the wreath allows the density as 25 ppm, the Isophorone allows the density as 5 ppm, all is all the high risk bane material, and often neglect these two kinds of bane thing the examination in the business unit. The printing ink solvent taste dispersed at the scene to sample is very thick, the harmful thing representing the scene is a bit high in thickness in the air, the real data finds, the harmful things are not tall in thickness in the air after measuring. Among them the sense of smell of materials such as ketone,etc. is worth being all very low sensitively and awarely for Ethylene glycol monoethyl ether acetate, the Cyclohexanone and Isophorone, will lead to the fact the labourer has uncomfortable phenomena to take place in the homework of scene. Screen printing in the work course, it should belong to and wash a edition of work that the solvent exposes the most serious work, secondly put treating the universe things on the semi-manufactured goods shelf engaged in the place, should set up the effective some discharger, reduce and expose in labourer's harmful environment.
