In 1985, ASARCO Incorporated terminated copper smelting operations and associated byproduct arsenic trioxide recovery at Tacoma, WA, although shipments of arsenic trioxide from stocks and limited production from cleanup operations continued. Imports of arsenic trioxide increased markedly as a result of increased demand for arsenical wood preservatives and the decline in domestic shipments of trioxide. Expanded world capacity more than met the increased demand for arsenic and its compounds, and prices remained unchanged throughout the year. Domestic Data Coverage.-Arsenic trioxide was produced by one U.S. company, which voluntarily reported its production to the Bureau of Mines.
