Materials and methods

Principles of method if other than guideline:

BASF test: Four groups of 5 mice per dose were treated intraperitoneally with preparations of the test substance in suitable vehicle. Group-wise documentation of clinical signs was performed over the 7-day study period. Body weight was determined before the start of the study only, as it was needed for determination of dose. The clinical signs and findings were reported in summary form. On the basis of the observed lethality, the LD50 value was estimated or determined using a graphical evaluation of the dose response curve on probability paper.
