Description of key information

The BCF of EEA-NH4 is 5.8 in Japanese carp.

Key value for chemical safety assessment

BCF (aquatic species):
5.8 dimensionless

Additional information

A GLP-compliant OECD guideline 305 study is available (Kurume Laboratory, 2006a). Bioaccumulation of EEA-NH4 in Japanese carp (Cyprinus carpio) was tested at 2 and 20 μg/L under flow-through conditions (nominal concentrations). The BCFs of EEA-NH4 were not more than 5.8 at 2 μg/L and 0.59 at 20 μg/L. The BCFss was not calculated as the test concentrations in all test fish were below the detection limit of the substance. Because the BCFs were below 100 it was assumed that steady state was reached within 28 days.
