Description of key information

The test substance (N-Butyl-TAD) has a low potential for bioaccumulation, as the logKow is below 3.

Key value for chemical safety assessment

Additional information

In accordance with Regulation (EC) 1907/2006, column 2 of Annex IX, section 9.3.2, a bioaccumulation study need not be conducted if the substance has a low potential for bioaccumulation (e.g. Log Kow <3). The log Kow of the test substance has been estimated to be 2.88 by QSAR calculation. Hence, it can be concluded that the potential for bioaccumulation is low and no further testing is required.
