Description

"Cadmium oxide (CdO) may be in the form of a white amorphous powder or as red or brown crystals: it is formed when cadmium is burned or heated." [ACGIH]

Sources/Uses

Used in silver-zinc storage batteries, Teflon, phosphors, semiconductors, silver alloys, glass, nematocides, ascaricides, catalysts, electroplating, ceramic glazes, and PVC heat stabilizers; [HSDB] Combined with an alkali-metal cyanide in baths for cadmium electroplating; [Ullmann]

Comments

May cause respiratory tract irritation and pulmonary edema; May cause kidney injury; [ICSC] "Since the 1950s, reports have described emphysema due to cadmium fumes, particularly in workers exposed to cadmium oxide for long periods of time." [Christiani, p. 188] See "Cadmium."

Exposure Assessment
BEI

Cd in urine = 5 ug/g creatinine; Cd in blood = 5 ug/L; sampling time not critical; "Monitoring in blood should be preferred during the initial year of exposure and whenever changes in the degree of exposure are suspected." [ACGIH]
