inhalation exposure test using the guinea pigs, respiratory
and lung disorder, such as nasal-septum dropsy, pulmonary
emphysema, atelectasis, hyperemia, dropsy, bleeding and
thrombosis of bronchioles are observed at the
concentration range of guidance value of Category 1 of
GHS Specific target organ toxicity (repeated exposure).
Furthermore, in the 78-week inhalation exposure test using
a cynomolgus, histological change as hyperplasia of a cell,
the wall thickening, etc. in bronchioles of lungs were
observed at the dosage (0.048 mg/L, 23.5 Hr/Day) of the
guidance value range of Category 1. From the above, it was
classified as Category 1 of GHS Specific target organ
toxicity (repeated exposure) (respiratory systems).

(Acute hazardous to the aquatic environment : Category 1
of GHS Ecotoxicity)
Reliable chronic toxicity data has not been obtained. Since
it is metal compound, the behavior in water is not known.
Because acute toxicity is category 1, chronic hazardous to
the aquatic environment was classified as "Category 1 of
GHS Ecotoxicity ".
Persistence/degradability :
No data.
Bioaccumulation :
No data.
