Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category III
- Conclusions:
- Acute inhalation toxicity in male rats was reported to be 679 ppm(4144.538 mg/m3 =4.144 mg/L).
- Executive summary:
- Acute inhalation toxicity for test chemical was studied in male rats. male rats(head only) were exposed for a single 4 hour period at a concentration of 533ppm, 644 ppm, 782 ppm, and 923 ppm. Clinical signs during and immediately after exposure included cyanosis, tremors, semi prostration, reddish brown nasal discharge, hind limb ataxia, salivation, and abnormal arched back posture. Signs observed after 24 hours included: stained perineal area, pallor, and reddish brown nasal discharge. Thus, LC 50 value was reported to be 679 ppm(4144.538 mg/m3=4.144 mg/l)
