Air Flow: 10 liters per minute
Weight of material aerosolized: 2 g/minute
Nominal concentration of test material: 200 mg per Liter
GLP compliance:
no
Test type:
standard acute method
Limit test:
yes

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The substance demonstrated a 10% mortality rate and has been completed as a limit test at 200 mg/l The LD50 is considered to be >200 mg/l.
Executive summary:

The test sample was dosed by inhalation to 5 male and 5 female rats at a dose of 200 mg/l. Assessed over a 14 day period, 0 male and 1 female deaths occurred and the study was completed as a limit test. The LC50 is considered >200 mg/l.

 

No classification is applicable based on the results.
