Description

White, odorless solid; [NIOSH]

Sources/Uses

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]

Comments

Causes metal fume fever; [Rom, p. 404-6] See "Zinc."

IDLH (NIOSH)

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]
