• Description:
  Printing operations are a significant source of uncontrolled volatile organic compound (VOC) emissions. These emissions are a potential health hazard in the workplace and to the environment. Describing emissions in terms of an emission factor has the advantage of removing the effects of the surrounding airspace and therefore is a tool to predict emissions under a variety of operating conditions. Industrial hygiene surveys were done at three different sized offset lithography printing shops. Air pollutant concentrations, ventilation,and process variables were measured. Mass balance models were used to determine VOC emission rates. Process variables and the emission rates were correlated to develop emission factors. Total VOC concentrations at the three sites ranged from $<$1 to 178 $\rm mg/m\sp3.$ The smallest shop had the highest concentrations. Specific hazardous organic compound concentrations were generally low.Benzene, however, was measured at levels approaching and exceeding the action limit. VOC emission rates ranged from 0 to 2,530 g/hr. The modelled emission rates agreed with measures of bulk solvent use. The use of solvent for press cleaning operations was found to be the most significant determinant of VOC emissions. The emission factors for manual press cleaning in the three shops ranged from 25.0 to 66.0 g VOC emitted per cleaning event. Similar presses in different shops had similar emission factors.
