Short-term toxicity to aquatic invertebrates

Link to relevant study record(s)

Reference

Endpoint:

short-term toxicity to aquatic invertebrates

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

the study does not need to be conducted because a long-term aquatic toxicity study on invertebrates is proposed to be conducted

Description of key information

Due to the poorly water solubility and the very adsorptive behavior of the registered substance, the available experimental short-term toxicity study cannot be used to establish a trend for the aquatic toxicity of the substance. Time of exposure and preparation of acute testing are not sufficient or proven relevant. A data waiver for the short-term toxicity to aquatic invertebrates endpoint is therefore proposed due to the poorly water solubility of the substance and the testing proposal for a long-term toxicity study to aquatic invertebrates on the registered substance.
