Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The bioaccumulation potential of silatrizole was investigated in a GLP-compliant test conducted in accordance with OECD Guideline 305. Under the test conditions, the bluegill sunfish (Lepomis macrochirus) showed a negligible bioconcentration of silatrizole of about 10 at concentration of 2 µg/l (low dose) and 20 µg/l (high dose). Analyses of radioactivity in the organic phase of the exposure water showed almost exclusively parent item at both dose levels during the entire exposure period. Taking into account the actual concentration of the test item in the exposure water of 1.40 and 16.28 µg/l, the average parent BCF value in whole fish amounted to 11 ± 5. When based on lipid content, the overall lipid BCF amounted to 160 ± 78.

Additional information
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.
