The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Only one study was available for this endpoint (Sato, 2007). The experiment was conducted following the test method relating to new chemical substances (Yakushokuhatsu no. 1121002, Heisei 15.11.13 Seikyoku no. 2, Kanpokihatsu no. 031121002, november 21, 2003; the latest version, 2006). Two different concentrations were tested: 0.05 and 0.5 mg/L, during 60 days.
After the pretreatment, analysis was conducted using liquid chromatography mass spectrometry (LC/MS). At the high concentration level, the variations of the bioconcentration factors consecutively measured 3 times at intervals of more than 48 hours could not be confirmed to fall within +/-20% for peaks A, B, and C. Because the concentration factors during the exposure period were all less than 100, the bioconcentration factors were deemed to reach the steady-state. The bioconcentration factors at the steady-state were =< 50 (peak A), <11 (peak B), and <22 (peak C).
At the low concentration level, all the bioconcentration factors during the exposure period were less than the detection limit. The bioconcentration factors during the exposure period were <191 (peak A), <102 (peak B), and <222 (peak C).
Based on the results of Sato (2007), the bioaccumulation potential of the test substance in fish tissues is judged to be low.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
