(DFG 2006).
|
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:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
Repeated or prolonged inhalation exposure may cause asthma.
The substance may have effects on the heart,
thyroid
and
bone marrow
, resulting in cardiomyopathy, goitre and polycythemia.
This substance is possibly carcinogenic to humans.
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
Animal tests show that this substance possibly causes malformations in human babies.
