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.
