- Gross pathology:
- Red liquid was found in the stomach of one decedent and red liquid was found in the intestines of another decedent. Animals sacrificed at study termination on day 14 were found to be normal at necropsy.

Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- Based on the results of the acute oral toxicity study of lithium nitrate a LD50 of 1317 (male), 1519 (female) and 1426 (Combined) mg/kg bw was derived.
- Executive summary:
Groups of five male and female Sprague-Dawley rats were orally administered lithium nitrate by a 25 % (w/v) preparation in tap water. Observations for toxicity were conducted 0.5, 1, 2, 3, 4, and 6 hours post-dosing, and daily thereafter for fourteen days. Body weights were recorded weekly and prior to necropsy. Gross necropsies were performed on all animals. All deaths occurred within 5 days of dosing. The most significant clinical signs were twitching, rolling over in cage, recumbency, loss of muscle control, squinting eyes and tremors. All signs subsided by study day 6; surviving rats remained healthy and gained weight until study termination. Red liquid was found in the stomach of one and in the intestine of another decedent. Animals sacrificed at study termination on day 14 were found to be normal at necropsy. The LD50 values determined were 1317 mg/kg in male rats, 1519 mg/kg in female rats, and 1426 mg/kg in combined sexes.
