Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Two short-term toxicity studies with Diphenyl Oxide (DPO or Dipheny Ether) were conducted with Daphnia magna following available guidelines at different laboratories. A quantitative structure-activity relationship (QSAR) model was used to estimate the acute toxicity.
Key value for chemical safety assessment
Fresh water invertebrates

- 1.96 mg/L
Additional information
One key study was identified that provided acute toxicity test results with Daphnia magna exposed to Diphenyl Oxide (DPO or Diphenyl Ether). This study was rated a Klimisch score of 1 and was considered reliable reporting a 48-hr EC50 value of 1.96 mg/L (95% confidence interval of 1.74 - 2.21 mg/L).
A supporting study was rated a Klimisch score of 1 and was considered reliable reporting a 48-hr LC50 value of 1.7 mg/L.
These results were corroborated by a quantitative structure-activity relationship (QSAR) model (ECOSAR v1.11 by U.S. Environmental Protection Agency, 2012) estimation which shows the 48-hr LC50 of 1.0 mg/L.
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.
