Description of key information
Bioaccumulation study conducted in accordance with "Test method for new chemical substances" determined in Regulation Number 392 (1974).
Key value for chemical safety assessment
- BCF (aquatic species):
- 2 dimensionless
Additional information
The experimentally-determined log Kow of 0.05 is substantially below the criterion of log Kow ˂ 3 at which bioaccumulation testing is not indicated, as described in Regulation (EC) No.1907/2006, Annex IX, Column 2. In addition, the bioaccumulation study of the substance in carp indicated that bioconcentration is not of concern; the BCF value ≤ 2 from the low concentration test and BCF≤ 0.7 from the high concentration test are each substantially below the definitive criteria for both bioaccumulative (> 2,000 L/kg) and very bioaccumulative (>5,000 L/kg). Therefore, bioaccumulation is not expected in the aquatic compartment.
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.
