Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Column 2 of REACH Annex VIII, the short-term studies for aquatic toxicity to invertebrates which is usually required in Section 9.1.1 do not need to be conducted for substances if there are mitigating factors indicating that aquatic toxicity is unlikely to occur such as if the substance is highly insoluble in water.
The water solubility of the test material was investigated in accordance with the standardised guidelines OECD 105, EU Method A6 and OPPTS 830.7840 under GLP conditions. It proved difficult to obtain a solution of the test material for water solubility testing. Under the conditions of this study, the water solubility of the dissolved material was < 0.000728 mg/L. The substance is therefore considered highly insoluble in water and testing on the short-term toxicity to invertebrates does not therefore need to be conducted.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
