Additional information

The performance of a test for bioaccumulation in aquatic species, preferably fish, is scientifically unjustified.

REACH Regulation No. 1907/2006, Annex IX, Sect. 9.3.2, Col. 2, states as follows:

“9.3.2 The study need not be conducted if:

- the substance has a low potential for bioaccumulation (for instance a log Kow <= 3) and/or a low potential to cross biological membranes, or

- direct and indirect exposure of the aquatic environment is unlikely. ”

The Log Pow of the test substance (Diflufenzopyr sodium salt) was calculated to be -0.59 at 25 °C. Therefore, the test substance was considered to have no bioaccumulation potential.
