Abstract A literature review and source tests were performed in order to accurately characterize emissions from hot-dip galvanizing processes. Particulate emission data from seventeen source tests on hot-dip galvanizing plants were considered relevant in developing an emission factor for galvanizing kettles. There was no significant difference between kettle emissions and emissions from control devices. Considering both kettle and control device emissions as one data base, two types of emission factors were calculated: (1) An emission factor based on process weight, equal to 0.26 kg/metric ton galvanized product (o = 0.28), or assuming 8% zinc by weight in the galvanized product, 3.3 kg/metric ton zinc used (o = 3.5). (2) An emission factor based on the hours of kettle operation, equal to 0.51 kg/hr per kettle (o = 0.44). Using the derived emission factors, the total amount of particulate emissions produced by hot-dip galvanizing operations in the United States is estimated to be approximately 1,600 metric tons per year.
