- Executive summary:
Method
The test substance was tested for Acute Oral Toxicity on rats according to a method similar to the OECD Guideline 401. Five animals per sex per dose were administered by gavage with the test item at four different concentrations ( 1000, 2000, 3000 and 5000 mg/kg bw).
Observations
During the treatment and observation period the animals were housed in groups of 5 in Macrolon cages. Animals fasted overnight were treated by oral intubation. Physical condition and rate of deaths were monitored throughout the whole observation period.
During the test Sedation, Dyspnoea, Exophtalmos, Ruffled fur, Body Position (Curved) in all the concentration tested. Diarrhoea was observed at doses of 1000, 2000 and 3000 mg/kg bw. Convultions were observed at the dose of 5000 mg/kg bw.
At 1000 mg/kg bw no deaths occurred and at the maximum dose (5000 mg/kg bw) all the animals were found dead, at the other concentrations the following number of animals were found dead: 4 animals at 2000 mg/kg bw and 9 animals at 3000 mg/kg bw.
Conclusion
LD50 (male/female) = 2122 mg/kg bw
