Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

According to Annex VII, section 9.2, Column 2 of Regulation (EC) 1907/2006 and ECHA Guidance on information requirements and CSA, Chapter R.7b – Endpoint Specific Guidance, version 1.2; November 2012, a study on ready biodegradability does not need to be conducted if the substance is inorganic.

Hence, degradation/biodegradation testing is not relevant for metals and metal compounds such as barium dichloride, which are considered as not (bio)degradable.

Furthermore, for an inorganic substance for which the chemical assessment is based on the elemental concentration (i.e., pooling all inorganic speciation forms together), biotic degradation is an irrelevant process: biotic processes may alter the speciation form of an element, but it will not eliminate the element from the sediment compartment by degradation or transformation. This elemental-based assessment (pooling all speciation forms together) can be considered as a worst-case assumption for the chemical assessment.
