摘要

Information is provided regarding rhe nature,magnitude,and extent of the emissions of selenium in the United States for the year 1969. Background information concerning the basic characteristics of the selenium industry has been assembled and included. Brief 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 986tons. The emissions that resulted from the combustion of coal were about 65percent of total emissions,and those due to the manufacture of glass were nearly 21percent. Emissions from metallurgical processing of nonferrous metals and the burning of fuel oil were 9percent and 7percent respectively,while all other emissions were less than one percent of the total.
