Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
Bioaccumulation: aquatic / sediment
No measured data regarding bioccumulation is available. However, the bioconcentration factor (BCF) of the test substance can be determined by the computer program BCFBAFWIN v3.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). Furthermore, the whole body primary biotransformation rate estimation for fish was calculated with the notation that the bio half-life normalized to 10 g fish at 15 °C. It is possible to predict the apparent metabolism half-life in fish for three different trophic levels (lower, mid and upper). Using the regression-based estimate (traditional method) a BCF of 3.16 L/kg wet-wt was calculated. Using the Arnot-Gobas method, which is based on the mechanistic first principles, the BCF results in a value of 0.90 L/kg wet-wt. The whole body primary biotransformation rate estimate for fish gives a half-life of 0.004869 days, whereby the rate constant (kM) for 10 g fish is designed as 125/day. This is taken into account to predict the apparent metabolism half-life in fish for the substance. For the lower trophic level a BCF of 0.9410 L/kg wet-wt is calculated, whereas for the mid trophic level the BCF will result in 0.9323 L/kg wet-wt and the higher trophic level gives a value of 0.8937 L/kg wet-wt. The metal compounds (Na, K, Li) were removed for its calculation procedure. This procedure is regarded as a scientifically accepted calculation method and can be considered as reliable with restrictions. Furthermore, it can be used for the chemical safety assessment.

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.
