Description of key information

Additional information

There are many studies available which do not report sufficient information for BCF values to be calculated, and in many cases the tests were of short duration, and steady state was not achieved during the test. The available reliable studies suggest low BCF values for fish, although studies into the accumulation by molluscs, such as Hedouin et al. (2006), indicate the potential for higher BAF values for these organisms.

The study selected as key for assessment of this endpoint is Baudin et al. (1993) in which carp were exposed to approximately 0.2 ug/L. A steady state concentration in fish was achieved after 30 days, and a BCF value of 70 was calculated for the whole fish on a wet weight basis.

No relevant and reliable studies were available for the bioaccumulation of silver in terrestrial organisms.
