An emission inventory has been prepared to determine the nature, magnitude, and extent of the emissions of vanadium in the United States for the year 1968. The production and use of vanadium in the U.S. has been traced and charted. The consumption was 5,495 tons, exports 741 tons, and imports 652 tons. About 80% was used in the production of steel. Emissions to the atmosphere during the year totaled 19,231 tons. Emissions due to the combustion of fuel oil and coal were 17,000 tons and 1,750 tons respectively. Emissions resulting from the production of ferrovandium were 144 tons and those from the production of steel were 236 tons.
