A study of volatile organic compound (VOC) emission patterns in a printshop was conducted. Industrial monitoring was performed by air sampling for 16 specific VOCs or classes of VOCs in a print shop containing four offset sheetfed presses and three spirit duplicators used for imprinting letterheads on stationery and envelopes. Work activities were monitored and ventilation rates were measured. Total VOCs and 13 hydrocarbons in the air samples and cleaning solvents were analyzed by gas chromatography. The data were used to calculate VOC emission rates and emission factors. VOC emission rates across all work activities varied from 160 to 1,100 grams per hour (g/hr), mean 470g/hr. The emission rates correlated well with the concentrations of total VOCs, hexane (110543), toluene (108883), and other aromatic hydrocarbons containing nine carbon atoms which were derived from estimated solvent usage and measured solvent compositions. The highest emission rates were associated with press cleaning. VOC emission factors ranged up to 51 grams per work activity. The largest values were also associated with press cleaning. Based on the data obtained in this study, the authors conclude that a small print shop is likely to release 1 to 2 tons of VOCs per year into the environment. These releases represent a significant contribution to pollution by hazardous agents such as toluene, benzene, and ozone precursors.
