Description of key information

Additional information

For aquatic bioaccumulation, several studies are available for the substance. The key study, a flow through study in rainbow trout conducted at the saturation concentration yielded a steady state BCF of 600 for the test substance and 1146 based on total radioactivity. However, other studies report BCFs of 4000 to 9000.

 

For terrestrial bioaccumulation, a number of literature sources are available. The key study is a paper by Princz et al (2014) which includes reliable test data on the substance and shows that it does not bioaccumulate in the terrestrial speciesEisenia Andrei. A number of other papers offer conflicting results on the BCF of the substance, all of which are based on theoretical modelling and not considered as reliable as validated study data. It is therefore concluded that the Princz study provides the most useful results, with a BSAF of 0.13 – 0.32 g organic carbon/g lipid in a clay soil and 0.067 – 3.5 g organic carbon/g lipid in a sandy soil. The test substance is not expected to bioaccumulate in terrestrial species.
