Key value for chemical safety assessment
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 plants is not considered necessary and therefore not provided.
Reaction mass of bis(2-hydroxyethanaminium) sulfite and 2-(methylamino)ethanol - oxosulfane oxide (1:1) is soluble in water and soil moisture and dissociates to 2 -(methylamino)ethanol, (2- hydroxyethyl)ammonium and sulphite ions.
In a publication by Bergmann and Eckert (1990) the effect of one of the dissociation products 2-aminoethanol (CAS 141-43-5) on the growth and development of barley and rye was investigated. The applied use rates resulted in a promotion of basal stem growth and an increased grain yield. In another publication by Bergmann et al. published in 1991 the effect of 2 -aminoethanol on the grain yield of barly, rye and wheat was evaluated. Again 2 -aminoethanol had a stimulating effect on grain production. Adverse effects due to the exposure to 2 -aminoethanol were not described.
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.
