EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

Effects of short-term exposure

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

Effects of long-term or repeated exposure
The substance may have effects on the liver.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in seafood.

NOTES
The substance accumulates in fat tissues and can be excreted in breast milk. Technical pentabromodiphenyl ether is a mixture of tetra-, penta-, and hexabromodiphenyl ethers.
