Description of key information

Based on a read-across from an experimental GLP study performed on the analogue substance Cistus concrete according to the OECD 301F guideline, the registered substance is considered to be not readily biodegradable, because the degradation rate of the test item was 49% at day 28 (THOD-NH4). In addition, the biodegradation rate was 52% after 60 days of incubation.

Additional information

Ready biodegradability study on the registered substance was not available. However, an experimental study performed on an analogue substance (Cistus concrete) in order to assess its ready biodegradability was available. This study was performed under GLP conditions, and in compliance with OECD 301F guideline. In addition, this study has been reviewed and was considered reliable for that endpoint. Indeed, it respected the requirements of the guideline and the validity criteria were fulfilled. Therefore, it has been decided to use the result of this study for the registered substance. The read-across justification can be found in the related iuclid study record.
