Popis: The printing industry emits large quantities of volatile organic compounds (VOCs) that impact workplace and ambient air quality. Emission factors are a useful way to describe these emissions. Emission factors describe the mass release of a pollutant in terms of a process activity related to the emissions, and are useful for concentration modeling, evaluation and prioritization of engineering control efforts, and development of logical exposure assessment strategies. Three offset printing facilities of various sizes were evaluated for VOC air concentrations, ventilation characteristics, and process activities. The air concentration and ventilation data were used in mass balance models to determine the hourly VOC emission rates. Emission rates were validated with measures of bulk solvent use. Average VOC emission rates at three sites ranged from 178 to 1076 g/h. On a mass VOC emitted/area printed basis, the smallest print shop emitted up to 12 times the amount from the other sites (29 versus 3.9 an...
