1 462 mg/m³ air
Exp. duration:
4 h
Remarks on result:
other: mg/m³ calculated as mg/m³ = ppm *(MW/24.45)=ppm*(143.01/24.45)=250*143.01/24.45=1462 mg/m³

Applicant's summary and conclusion

Interpretation of results:
Toxicity Category II
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
4 h LD50 inhalation is about 1.46 mg/L (250 ppm)
Executive summary:

"Exposure of rats to 250 ppm for 4 hours caused death in about half the animals (Carpenter et al. 1949)." (cited in ATSDR 1989, page 14)

This is equivalent to 1.462 mg/L.
