Bioaccumulation testing for EDTA-FeNa.3H2O is not required, as the substance has a low potential for bioaccumulation (the log Kow is <3). A 28- day BCF study in fish (Lepomis macrochirus) for EDTA-Na4 (CAS 64 -02 -8, see IUCLID section 13 for read-across justification) supports this, as this study showed that 14C-EDTA exhibited an extremely low bioaccumulation potential with a BCF between 1 and 2 (Bishop & Maki, 1980).
