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 10 animals/sex was treated by single gavage with an aqueous suspension of the test substance. The animals were observed for mortality and for clinical symptoms of toxicity. They were weighed prior to treatment only. At the end of the observation period of 14 days, the surviving animals were sacrificed for the purpose of necropsy.
