- Dose descriptor:
- LD50
- Effect level:
- 4 100 mg/kg bw
- Based on:
- test mat.
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- 939 mg/kg bw
- Based on:
- element
- Remarks:
- Zr
- Mortality:
- The rats showed a progressive depression and decrease in activity until death occurred. The toxicity was considerably greater when sodium zirconyl sulfate was administered intraperitoneally (compared to oral gavage).
- Clinical signs:
- No characteristic physiologic changes were observed.
- Body weight:
- No characteristic physiologic changes were observed.
- Gross pathology:
- No characteristic gross pathologic changes were observed.
Applicant's summary and conclusion
- Conclusions:
- The acute LD50 value via the intraperitoneal route in rats is 4100 mg/kg bw for sodium zirconyl sulfate.
