Description of key information
Additional information
The potential for bioaccumulation was investigated in a study using radiolabeled test substance (2007). The test substance accumulated in bluegill sunfish with a total residue kinetic bioconcentration factor of about 275.5 to 289.8 for whole fish (sum of radio labelled compounds, parent substances, metabolites and mineralization products). When exposure ceases, the residues were depurated with a half-life of about 0.42 to 0.55 days. After 14 days in uncontaminated water 100% of the mean plateau radioactivities were depurated from whole fish in both test levels. Accumulations of total residues in edible parts were less (116.9 – 153.6) than in whole fish (275.5 – 289.8). Taking into account that about 30% parent compound were detected in edible parts and about 16% parent compound in non-edible (viscera) parts after 15 days of exposure the steady-state-BCF for parent (based on whole fish, wet weight) is about 71, the steady-state-BCF for parent (normalised to 6% lipid content) is about 54. Thus, the substance to be registered has a low potential to bioaccumulate in aquatic organisms.
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.
