- Executive summary:
The test material was administered to male and female rats as single oral gavage at dose levels of 316, 215, 147, and 100 mg/kg bw. Animals were observed for 14 days. Clinical findings consisted in dyspnea, apathia, prone position, ataxia, piloerection, exsiccosis, bad general condition, and diarrhea; females showed in addition: atony, tremor, convulions, cyanosis, and paresis. Red discolored faeces, urine and skin were observed during the first two days after treatment.
The following mortality was observed:
316 mg/kg: all animals within 2 days
215 mg/kg: 2 males within 3 days, 3 females withinf 2 days
147 mg/kg: 1 male within 2 days; all females within 2 days
100 mg/kg: no deaths
The bodyweight in surviving animals developed normally. No abnormal findings were detected at necropsy.
The LD50 for the test material was about 150 mg/kg bw after single oral gavage in aqueous CMC suspension.
