Description of key information

Additional information

The test substance is not supposed to be directly applied to soil and an indirect exposure to soil via sewage sludge transfer is unlikely since the substance is rapidly biodegradable. For a substance being considered as rapidly biodegradable, it can be assumed that it will be biodegraded within the STP process and as a consequence a transfer to the soil compartment is not expected. In addtion, the substance does have a very high water solubility and its physico-chemical properties do not indicate bioaccumulation and/or adsorption to soil. Due to rapid oxidation of sulphite / disulphite substances under environmental conditions (worst-case half-life of 77 h), no relevant test design and toxicity data can be generated.

Conclusively, a study on the toxicity to terrestrial organisms is not considered necessary and therefore not provided.
