Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
A reliable guideline-study on the chronic toxicity of hydrogen peroxide to Daphnia magna is available that resulted in a NOEC of 0.63 mg/L.
Key value for chemical safety assessment
Additional information
Data are available from the public domain on a reproduction test in Daphnia magna (Meinertz et al. 2008) conducted according to ASTM guidance (E 1193-97). Daphnids were exposed under flow-through conditions for 21 days to a range of concentrations, i.e., 0.32, 0.63, 1.25, 2.5 and 5.0 mg/L. Survival and reproduction of parent generation was not affected at concentrations up to and including 1.25 mg/L. Body length of adult water flea was statistically significantly reduced after 21 days at 0.32 mg/L compared to the control, however, the difference was so small that it is considered not biologically meaningful. Therefore, a NOEC of 0.63 mg/L is considered under the test conditions.
A further supporting long-term test with invertebrates is available from public literature addressing potential adverse effects of Fenton’s reagent (hydrogen peroxide in combination with ferrous ion) on zebra mussel Dreissena polymorpha (Klerks and Fraleigh, 1991). In the 56-day flow-through test (11 °C; pH 8.25; average concentrations hydrogen peroxide/total iron: 0.79/0.33, 1.62/0.61 and 4.47/1.53 mg/L), the NOECmortality for zebra mussel was 1.62 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.
