Demand for arsenic trioxide increased markedly during 1984 as a result of increased use of arsenical wood preservatives and increased use of arsenicals in agriculture. The increase in agricultural demand was due to a return to production of land with-held from cotton planting under an agriculture program for acreage diversion for some 1983 crops. Supplies of arsenic trioxide were more than adequate to meet increased demand, and prices either declined from, or remained at, the low 1983 levels. In June, ASARCO Incorporated announced plans to close its Tacoma, WA, smelter by mid-1985. Domestic Data Coverage.-Refined arsenic trioxide was produced by two U.S. companies. The major producer voluntarily reported its production to the Bureau of Mines, but to prevent disclosure of proprietary data, the production data have been withheld.
