Although the announcement specificationplacts of Indoor Air Quality Management Act does not include printing plant,the indoor air quality of printing plants using green ink have a considerable impact on the health of workers. In this study, the use of environmentally friendly printing ink in central Taiwan was selected as investigated site. The sampling locations include: outdoor, four-color printing nearby, colored printing nearby, the air conditioner inlet, research rooms and office. Indoor air quality monitoring items include: carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (HCHO), total volatile organic compounds (TVOC), bacteria, fungi, PM10, PM2.5. The TVOCs exceeding the EPA's threshold of 0.56 ppm occurred in all monitoring sites. PM2.5 in the process zone is slightly higher than the EPA's suggested value of 35 μg /m3. The bacteria as well as fungi concentrations are lower than the recommended values. The major bacterial are Bacillus sp, Bacillus toyonensis, Staphylococcus, Micrococcus luteus. The major fungal Cladosporium, Penicillium, Mucor, Non-sporulating.
