Description of key information

Read across: An experimental study on the structural analogue 2-ethylhexyl methacrylate (log Kow > 4) (Schäfers, 2006) of bioconcentration of the substance, according to OECD guideline 305 demonstrates that a rapid metabolism occurs, this depuration prevents any significant accumulation (BCF = 37).

Key value for chemical safety assessment

BCF (aquatic species):
37

Additional information

The octanol/water partition coefficient of the substances, log Kow > 4, predicts a potential for bioaccumulation.

Simple models linking BCF to log Kow would give BCF in the range of about > 1000 depending on the model and the log Kow used .

On the contrary, an experimental study (Fraunhofer, 2006) has been carried out on the structural analogue 2-ethyl hexyl methacrylate (log Kow > 4) to assess the fish bioconcentration of the substance, according to OECD guideline 305. This study demonstrates that a rapid metabolism occurs, and this depuration prevents any significant accumulation (BCF = 37).
