Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the findings of this study, a single dermal administration of lithium nitrate did not induce mortality as well as test item related adverse effects. A LD50 of >2000 mg/kg bw was determined.
- Executive summary:
Lithium nitrate was topically applied to five Sprague-Dawley rats per sex at a dosage level of 2000 mg/kg bw. The test material was in contact with the skin under an occlusive wrap for 24 hours. Observations for toxicity were conducted 0.5, 1, 2, 3, 4, and 6 hours post-dosing, and daily thereafter for fourteen days. Dermal irritation was recorded on days 1, 3, 7 and 14. Body weights were recorded weekly. Gross necropsies were performed on all animals.
No deaths were noted. Clinical signs noted during the study included abnormal posture, exaggerated hindlimb flexion, staggered gait, abdominogenital staining, abdominal gripping, no feces, chromodacryorrhea, decreased locomotion, diarrhea and unthriftiness. All but one rat recovered by study day 2; one male displayed signs until study day 8. All rats gained weight by day 14 of the study. Irritation noted included erythema of the test sites in all rats on day 1. Desquamation, erythema and eschar were noted in some animals on days 3, 7 and 14. No gross lesions were revealed during necropsy. The LD50 determined was greater than 2000 mg/kg bw in both male and female rats. (FMC, 1999)
