Description of key information
The lowest reported 96 hour LC50 was 1.2 μg Ag/L for Pimephales promelas (Bielmeyer et al., 2007).
Key value for chemical safety assessment
Additional information
Data were available from several published sources on the acute toxicity of silver to freshwater fish when silver nitrate was used as the test substance. The most sensitive 96-hour LC50 is reported by Bielmeyer et al. (2007) for fathead minnow. Although some details of the method used were not reported, similar LC50 values are reported by other authors (e.g. Karen et al., 1999).
Data on the toxicity of silver to marine fish are more limited. However, the data indicate that marine fish are considerably less sensitive to silver than freshwater species. The most sensitive 96-hour LC50 for marine fish is 331 μg Ag/L for Oligocottus maculosus (Shaw et al., 1988).
