Materials and methods
- Principles of method if other than guideline:
- BASF-Test. The study was conducted according to an internal BASF method which in principle is comparable to the OECD Guideline 401.
A test group consisting of 5 animals/sex was treated by single gavage application with an aqueous solution of the test substance. The animals were observed for mortality and for clinical symptoms of toxicity. They were weighed prior treatment and thereafter, day 3, day 7 and day 13 post-treatment. At the end of the observation period of 14 days, the surviving animals were sacrificed for the purpose of necropsy; animals that died during the observations period also were subjected to necropsy.
The LD50 value was estimated on the basis of the observed mortalities. - GLP compliance:
- no
- Limit test:
- no
