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 nuisance-causing 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 blood. This may result in anaemia.

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

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to algae and aquatic plants. 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
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties.
