Bioaccumulation: aquatic / sediment 


In a dietary study according to OECD TG 305 under flow-through conditions with Oncorhynchus mykiss the lipid normalized BMF was calculated to be 0.1218. The half-life (DT 50) for elimination of BMDBM during the depuration phase was 3.83 days. The growth corrected rate constant K2 for depuration was calculated to be 0.1811. In compliance with the guidance document to OECD TG 305 (2nd draft, 2016) the kinetic BMF value obtained from the OECD 305 study was translated into BCF values by using the excel spreadsheet published by OECD (version 2, as provided on 10 December 2020). Based on the experimental data and current guidance the BCF of the test item is considered to be in the range between 2000 and 3000. An in-depth assessment on the bioaccumulation potential of the substance is attached to IUCLID section 13.2.
