Metals, Inorganic Compounds
White, odorless solid; [NIOSH]
Used in pigments, rubber, and electronic devices; Zinc oxide is produced when zinc is heated to its boiling point (907 degrees C); [ACGIH] Nanoparticle applications include sunscreen and fungicide for personal care products, UV nanolasers, biocide in food packaging, additive to rubber and ceramics for abrasion resistance, and additive to automobiles, furniture, and fabrics to protect from sun damage; [HSDB]
Causes metal fume fever; [Rom, p. 404-6] See "Zinc."

Exposure Assessment

Skin Designation (ACGIH)
Insufficient data
2 mg/m3 (respirable fraction)
10 mg/m3, respirable fraction
5 mg/m3(fume and respirable fraction), 15 mg/m3(total dust)
0.1 mg/m3 (respirable fraction), 2 mg/m3 (inhalable fraction) [fume and solids]
500 mg/m3
Excerpts from Documentation for IDLHs
Human data: Workers exposed to zinc concentrations between 320 to 580 mg/m3 for 1­3 hours have experienced nausea on the job, and chills, shortness of breath, and severe chest pains 2 to 12 hours later [Hammond 1944]. Two men exposed to about 600 mg/m3 for 10.5 to 12 minutes experienced headaches, chills, and fever with cough and a decrease in vital capacity which persisted for 15 hours after exposure [Sturgis and Thompson 1927].
Lethal Concentration
LC50 (mouse) = 2,500 mg/m3
Explanatory Notes
Zinc melting point = 786 degrees F;
Half Life
For zinc, whole body: 162-500 days; [TDR, p. 1245]
