Description of key information

Long-term exposure of fish to sodium percarbonate is not expected.

Key value for chemical safety assessment

Additional information

Long-term exposure of fish to sodium percarbonate is not expected. Due to the intended use of the substance no significant release and no direct exposure of aquatic biota to the product are expected. Furthermore, sodium percarbonate in the aquatic environment rapidly dissolves into sodium carbonate and hydrogen peroxide. Hence, the chronic toxicity of sodium percarbonate can be derived from its components. Carbonates are considered to be widely and naturally occurring in the environment and act as buffers. Hydrogen peroxide has a short half-life in natural waters due to the activity of micro-organisms and other degradation processes, and therefore long-term exposure of aquatic biota, i.a. invertebrates to hydrogen peroxide originating from anthropogenic sources is considered rather improbable. Furthermore, hydrogen peroxide is continuously formed in the environment and is ubiquitous in fresh- and seawater at natural background concentrations from some micrograms to some tens of micrograms per litre. Accordingly, fish can be considered evolutionary adapted to hydrogen peroxide in this range of concentrations. In considerations of these points, a prolonged toxicity test in fish is found not to be necessary.
