Arsenic Trioxide Production.
NIOSH 1976 Feb:220-225
Arsenic-trioxide (1327533) is a by-product, principally of copper smelting. The arsenic (7440382) is present in small percentages in copper ores and concentrates. It is volatilized, oxidized, and recovered as a dust in the several stages of smelting. The crude product is refined and marketed to be used in glassmaking or as the raw material for arsenical compounds, important in agriculture and industry. Data are given regarding the proposed standard for threshold limit values of arsenic-trioxide in the air and results of sampling yielded by attempts to correlate urinary arsenic with airborne arsenic.
