Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- Male: 2000 mg/kg bw; Number of animals: 5; Number of deaths: 0
Female: 2000 mg/kg bw; Number of animals: 5; Number of deaths: 0 - Clinical signs:
- other: Signs of toxicity related to dose levels: No treatment related effects were observed. All animals gained weight during the 14-day observation period. Some animals showed a slight dip in body weight on postdosing day 3.
- Gross pathology:
- Effects on organs:
No gross abnormalities were observed. - Other findings:
- Signs of toxicity (local):
Males: slight erythema.
Females: slight to moderate erythema, slight or moderate
encrustations and very slight or slight oedema during the
first week after exposure.
