The animals that died on day 3 and 4 showed ataxia at 24 hours followed by prostration and death. The surviving animals showed progressive drying and cracking, developing into shedding of skin and continuing up to end of the 14 days. Based on the results, an LD50 of 5000 mg/kg bw was obtained in the acute dermal toxicity study with rabbits. Based on the results, the substance is acutely toxic at 5000 mg/kg bw.

Additional information

Acute oral toxicity:

In an acute oral toxicity study performed equivalent to OECD 401 guideline, one group of 10 rats were orally exposed to Fleuramone. The rats were observed for signs of toxicity and clinical signs for a period of 14 days. No deaths occurred and no clinical signs were observed. Based on the results, an LD50 of >5000 mg/kg bw was obtained in the acute oral toxicity study with rats. Based on this result, the substance is not acute harmful.

Acute inhalation:

Acute inhalation is predicted based on the acute oral toxicity in accordance with the CLP guidance document (2015, 3.1.3.3.4.page 255). The acute inhalation is predicted to be > 13000 mg/m3 and the saturated vapour pressure is 54 mg/m3. This means that the acute inhalation concentration cannot be reached and therefore no acute inhalation is anticipated.

Acute dermal toxicity:

In an acute dermal toxicity study performed equivalent to OECD 402 guideline, one group of 6 rabbits were dermally exposed to 5000 mg/ kg bw of Fleuramone. The rabbits were observed for signs of toxicity and clinical signs for a period of 14 days. One animal died on day 3 and two animals died on day 4. The animals that died on day 3 and 4 showed ataxia at 24 hours followed by prostration and death. The surviving animals showed progressive drying and cracking, developing into shedding of skin and continuing up to end of the 14 days. Based on the results, an LD50 of 5000 mg/kg bw was obtained in the acute dermal toxicity study with rabbits.

Justification for classification or non-classification

The substance does not have to be classified for acute toxicity by the oral, inhalation and dermal route according to Regulation (EC) No. 1272/2008 and its updates.
