Description of key information

Bioaccumulation was tested in fish  (Cyprinus carpio) exposed for 28 days to the test material at concentrations of 0.5 and 0.05 mg/L in a flow through system. Regular concentration control analysis of the test media showed that the test material concentrations were maintained at 92 % of the nominal values, throughout the exposure period and that the test material was present in dissolved form, thus proving steady state exposure conditions. No signs of toxicity were observed throughout the study. Steady state BCFs of 56 and 15 were determined. Due to the low bioaccumulation potential, no depuration phase was required.
The steady state BCF values were at 56 and 15 The test item showed no relevant bioaccumulation (BCF < 2000).

Key value for chemical safety assessment

BCF (aquatic species):
