Biodegradation in water and sediment: simulation tests

Description of key information
A Final Decision letter (CCH-D-2114412576-50-01-F) was received for this substance on 09 July 2018 which requested further information on the PBT properties of the Block 10 Aldehyde consituents in this substance. As a first step Abietal was chosen to represent the Aldehyde Block 10 consituents and a ready biodegradation study was comissioned and depending on the outcome of that study the requirement for further testing for Persistence, Bioaccumulation and Toxicity would not be required.
The results show that Abietal meets the criteria in the OECD 301B to be labelled readily biodegradable e.g. at least 60% biodegradation in 28 days. Meeting the 10-day window was not a requirement according to both the ECHA Final Decision Letter and OECD guidance documents.
The test item is non-persistent, and satisfies the criteria to be labelled readily biodegradable based on the results obtained in the second experiment.
Therefore, no further work on the persistence of DTO or its consituents is required.
Key value for chemical safety assessment
Additional information
Biodegradation of DTO as a whole substance in sediments
In accordance with Column 2 of REACH Annex IX, the biodegradation in water and sediment study (required in Sections 9.2.1.2 and 9.2.1.4) does not need to be conducted as the substance is readily biodegradable. Identification of degradation products (required in Section 9.2.3) is also not necessary.
Biodegradation of DTO constituents in sediments
No measured sediment biodegradation data are available for constituents of DTO. An exposure assessment (Section 9) using EUSES 2.1.1 has been performed. The modelhas a very cautious approach to the estimation of biodegradation rate in the environment which is based on the TGD requirements. However, the rates are wholly unrealistic of what can reasonably be expected for naturally-occurring substances of high intrinsic degradability,and so a sediment half-life of 30 days has been set for all constituent blocks of DTO. The significance of that decision is considered in Section 9 of the CSR.
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.
