Information is provided regarding the nature, magnitude, and extent of the emissions of zinc in the United States for the year 1969. Background information concerning the basic characteristics of the zinc industry has been assembeled and included. Brief process descriptions are given; they are limited to the areas that are closely related to existing or potential atmospheric losses of the pollutant. Emissions to the atmosphere during the year were 159,922 tons. About 31 percent of the emissions resulted from the metallurgical processing of zinc, more than 30 percent from the production of iron and steel, and nearly 18 percent from the incineration of refuse. The production of zinc oxide, the wear of rubber tires, and the combustion of coal were also significant emmission sources.
