Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
At the start of the experiments and after 16 days the lengths of daphnids exposed to the test compound were measured. The NOEC on growth is defined as the highest concentration which did not result in a significant reduction in growth at P<0.001 (student's t-test).
GLP compliance:
no
