THE IMPACT OF DIGITAL PRINTING MACHINES ON INDOOR AIR QUALITY

Abstract

The objective of the study is to evaluate the indoor air quality in digital printing facility during the three working weeks (120 hours). For that purpose, mass concentrations of suspended particulate matter of diameter less than 10 μm (PM10) were monitored in addition to single-color and four-color digital machines. The cumulative mass concentrations values of PM10 for single-color digital machine were in the range from 1.36 to 9.90 μg/m3, and they are almost 1.4 and 2.2 times higher compared to the same values for the four-color machine (0.97 4.44 μg/m3). The obtained results could be useful for the risk assessment of indoor exposure to suspended PM10 particles, and for the creation of printing indoor air quality guidelines of the Republic of Serbia.
