Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- 500 mg/kg bw
- Mortality:
- One animal of step 1 (treated with the test item at a dose of 2000 mg/kg) was found dead 3 days post-dose and two animals of step 1 were found dead 5 days post-dose. All animals of the second and third step (treated with the test item at a dose of 300 mg/kg) survived until the end of the study.
- Clinical signs:
- The most relevant clinical findings in the animals treated with the test item at a dose of 2000 mg/kg bw were piloerection, diarrhoea, wasp waist, nasal discharge and body weight loss.
All animals of the second and third step (treated with the test item at a dose of
300 mg/kg) survived until the end of the study.
The most relevant clinical findings in the animals treated with the test item at a dose of 300 mg/kg bw were piloerection and slightly reduced spontaneous activity. The clinical signs were observed only on the day of administration in these animals. - Body weight:
- Throughout the 14-day observation period, the weight gain of the animals treated with the test item at a dose of 300 mg/kg bw, was within the normal range of variation for this strain.
- Gross pathology:
- Necropsy of the 2000 mg/kg group revealed bloody nose and mouth in two animals. And in one animal the stomach was filled with discoloured material (blue/black). The Jejunum, ileum with Peyers`s Patch, caecum, colon and rectum were very small and filled with liquid only.
At necropsy, no macroscopic findings were observed in any animal of the 300 mg/kg group.

Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on an LD50 cut-off of 500 mg/kg bw the substance should be classified as harmful with the criteria given in Annex VI to Commission Directive 2001/59/EC as well as in Annex I of Regulation (EC) 1272/2008.
- Executive summary:
In an acute oral toxicity study, groups (3or 6/sex) of female Wistar rats were given a single oral dose of Ashes (residues), vanadium-contg. in water at doses of 2000 or 300 mg/kg bw. Animals were then observed for 14 days.
Oral LD50 cut-off = 500 mg/kg bw. The test material is classified as harmful.
This acute oral study is classified as acceptable. It does satisfy the guideline requirement for an acute oral toxicity study OECD 423 in the rats.
