Applicant's summary and conclusion
- Conclusions:
- Hydrogen peroxide released to the environment under equilibrium conditions will partition mainly into the water compartment.
- Executive summary:
The environmental distribution of hydrogen peroxide was modelled using a Level I Mackay model, which assumes partitioning at equilibrium (European Commission 2003). Similar distribution trends are seen in higher-tier environmental models. The following distribution behaviour was found for partitioning at equilibrium, i.e. environmental distribution of hydrogen peroxide predicted with a Level I Mackay model for different compartments in % of total mass: Air, 0.003; Water, 99.98; Soil, 0.01; Sediment, 0.01
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
