Any other information on results incl. tables

Nasal hemorrhage, sluggish locomotion and ruffled, unkempt coats were noted at 250 mg/kg. At dosage level of 500 mg/kg, 630 mg/kg and 800 mg/kg, the animals were lethargic with ruffled, unkempt coats. Spasmodic movements were noted. Within on hour, all animals were in a fetal position. Lacrimation, ocular and nasal hemorrhage were noted. Convulsions began approximately two hours after dosing. The animals dosed at 1000 mg/kg and 2000 mg/kg showed the same toxicity as at 800 mg/kg. All animals died within 2 -4 hours after incubation.

Applicant's summary and conclusion

Interpretation of results:
Toxicity Category IV
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
LD50 value of the test item is 725 mg/kg (male albino rats), therefore the test item will be classified as acute toxic; category 4; oral, H302.
Executive summary:

The study was performed 1976, before GLP- and OECD-testing guidelines were available and in force.

In this assay toxicity was recorded . LD50 value of the test item is 725 mg/kg (male albino rats), therefore the test item will be classified as

acute toxic; category 4; oral, H302 according to GHS/CLP classification criteria.
