Description of key information

In accordance with column 2 of REACH Annex IX, the aquatic / sediment bioaccumulation study (required in section 9.3.2) does not need to be conducted as the substance is expected to have a low potential for bioaccumulation because it has a low octanol water partition coefficient (log Kow <3).

A supporting QSAR reported BCF and BAF values between 0.9639 - 0.9936 L/kg wet weight (including biotransformation rate estimates) and 1.013 -1.015 L/kg wet weight (assuming a biotransformation rate of zero).

Key value for chemical safety assessment

BCF (aquatic species):
1.015 L/kg ww

Additional information

The BCF and BAF values were estimated by the Arnot-Gobas BCF and BAF Methods in the following QSAR:
