Description of key information

The concentration of the test substance in fish ranged from 0.37 to 1.08 µg/g (w/w) and the bioconcentration (BCF) was 2 to 5. On the basis of the BCF obtained, it is concluded that the bioaccumulation potential of the test substance in fish is low under the test condition.

Key value for chemical safety assessment

BCF (aquatic species):
5 dimensionless

Additional information

"Should read: BCF= 2 - 5"

As the test substance has a very low water solubility HCO-30 was used as solubilizer in the test system. If possible no solubilizer should be applied to the test system. But as the results for the BCF are very small and the usage of a solubilizer is increasing the concentration of the test substance in the test system, the present result can be used as a worst case displaying a very low bioaccumulation potential for the substance under environmentally relevant conditions.
