Description of key information

The most sensitive data reported is a 96 hour LC50 of 1.2 μg Ag/L for Pimephales promelas (Bielmeyer et al. 2007).

Key value for chemical safety assessment

Additional information

The most sensitive 96-hour LC50 is reported by Bielmeyer et al. (2007) for fathead minnow. 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).
