  In Air Pollution Control Act revised in 2004, voluntary effort of small and medium-sized factories out of the regulation is a key to VOC emission reductions. Thus the development of VOC treatment devices which can be introduced by employers of small and medium-sized factories is necessary. In this study, to get information for developing effective treatment devices we conducted field surveys of VOC emissions in small-scale printing and paint factories. VOC and carbonyl compound concentrations in printing booths, painting booths, drying ovens and each duct were measured by GC/MS and HPLC. As a result, it was suggested that many kinds of VOC other than VOC components consisting of ink and paint were emitted by chemical reaction in operation processes or from solvents used in other processes. In addition, VOC concentrations and compositions varied according to the operation process. It can be concluded that treatability of various VOC is important in the case of developing effective treatment devices.
