Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are many studies in the literature relevant to the bioaccumulation of silver. However, many of these studies do not report sufficient information for BCF values to be calculated. In addition, many of the data were obtained from studies of short duration which did not achieve steady-state conditions. The available reliable studies suggest low BCF values for fish, although studies of the accumulation of silver by molluscs, such as Hedouin et al. (2006), indicate the potential for higher BAF values for these organisms.
As data on bioaccumulation for fish are preferentially selected for this information requirement under REACH, the key study selected for this endpoint is Baudin et al. (1993) in which carp were exposed to silver in water for a six-week period, followed by a depuration phase. A steady state concentration in fish was achieved after 30 days exposure and a BCF value of 70 was calculated for the whole fish on a wet weight basis.
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.
