Short-term toxicity to fish

Administrative data

Endpoint:

short-term toxicity to fish

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is highly insoluble in water, hence indicating that aquatic toxicity is unlikely to occur

Cross-reference

Reason / purpose for cross-reference:

reference to other study

Reference
