Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The UVCB environmental assessment is driven by the assessment of the individual UVCB constituents. The environmental assessment is based on selected ‘driving constituents’. For the environment, it is considered that it is the metal ion that is the toxic driver and that this will be the dominant form in emissions to the aquatic environment (ECHA, 2008, R.7.13-2). The parent compound of each driving constituent present in refinable substances is therefore typically not considered or relevant. Environmental fate information on the individual UVCB constituents is reported in the respective summary sheets for each constituent for which a quantitative exposure and risk assessment is conducted. The information is taken from the respective constituent IUCLID dossiers. More information on the scope of assessment for each constituent can be found in the introductions to Section 4 and Section 7 of this CSR.
