Description of key information

No significant adsorption of sodium perborate as well as its hydrolysis products in soil and the aquatic compartments is to be expected.

Key value for chemical safety assessment

Additional information

Studies on the environmental distribution behaviour of sodium perborate are not available. From the physico-chemical properties and the use pattern of sodium perborate it is obvious that the by far most important target compartment for the anthropogenic releases is the hydrosphere. From the ionic structure of the substances a significant volatilization from water is not to be expected. Due to the intended decomposition during use and the degradation in the aquatic environment an assessment of the adsorption behaviour should be derived from the data on the degradation products.
