EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of dust or fume, through the eyes and through the skin.

Effects of short-term exposure
Inhalation of fumes may cause metal fume fever. The effects may be delayed.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly , especially for fume.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
TLV: 4 mg/m³, as TWA; 10 mg/m³ as STEL

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

NOTES
No specific CAS number is indicated for ZnO nanoparticles. See ICSC 0208.
