EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol 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 or when dispersed, especially if powdered. 

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. 

NOTES
