Additional toxicological data
Administrative data
- Endpoint:
- additional toxicological information
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- No guideline study with some deficiencies: the rat is a poor animal for the study of experimental hypercholesteremia, requiring special diets and the feeding of cholesterol and saturated fats to develop high serum levels. The data on changes in serum cholesterol with age are incomplete.

Results and discussion
Any other information on results incl. tables
Serum cholesterol levels in mature rats given zirconium (12 rats/sex tested; age of rats: 893 days):
male rats: 89.7 ± 5.6 mg/100 mL
female rats: 100.7 ± 9.0 mg/100 mL
Compared with the controls given 1.0 ppm chromium, values for males were slightly elevated in the group fed zirconium.
Female control levels were the highest of any group. Other elevated values (> 100 mg/100 mL) occurred in the group given zirconium.
The observed effects were not significant.
Changes in circulating cholesterol levels with age: Increases occurred in rats of both sexes fed zirconium.
Applicant's summary and conclusion
- Conclusions:
- Compared with the controls given 1.0 ppm chromium, values for males were slightly elevated in the group fed zirconium.
Female control levels were the highest of any group. Other elevated values (> 100 mg/100 mL) occurred in the group given zirconium.
The observed effects were not significant. Increases in circulating cholesterol levels with age occurred in rats of both sexes fed zirconium.
