Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
and
by ingestion.
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 Short-Term Exposure:
The substance may cause effects on the
thyroid
.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
thyroid
, resulting in goitrogenic effects.
