Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- BCF (aquatic species):
- 85 L/kg ww
Additional information
A study was conducted to determine the uptake and elimination test material and its degradation products by bluegill sunfish (Lepomis sp.) exposed to constant levels of test material under conditions as described in Section 163.62-11(d), 163.165-3 and 163.165-4 E.P.A. proposed guidelines. The fish were exposed to either 0.50 ppm or 0.05 ppm test material in constantly flowing water and sacrificed at time intervals up to 30 days. Following this period, the remaining fish were placed in flow-through chambers without chemical and depurated for 14 days.
The bioconcentration factor (BCF) of the test material at the 0.05 ppm and 0.5 ppm treatment level was <85. Total 14C BCF's of 230 and 50 were determined for whole fish at 0.05 ppm and 0.5 ppm, respectively.
It is concluded that the potential for the test material, or its metabolites, to bioconcentrate in living organisms is minimal.
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.
