Abstract

The objective of this research is to study the relationship between the amount of paper and the amount of benzene released from the laser printer while printing. The benzene were collected by the Coconut Shell Charcoal Tube and analyzed by Gas Chromatography/ Flame Ionization Detector (GC/FID), The results of the study showed that the benzene concentration released from the printer during printing (30 samples) was in the range of 0.0467 - 0.0506 micrograms per cubic meter. The benzene concentration emitted from the laser printer does not exceed the standard value (allow to receive 25 ppm). The resulted of the relationship between the paper and the benzene concentration released from the laser printer while printing documents It is found that the amount of paper and the benzene concentration released from the laser printer were relate at very high level at the .01 Significance level. Considering that as the amount of paper increases, the benzene concentration also increases.
