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 when dispersed.
Effects of Short-Term Exposure:
May cause mechanical irritation.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
lungs
and
central nervous system
, resulting in increased susceptibility to bronchitis, pneumonitis and neurologic, neuropsychiatric disorders (manganism).
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
